Even at 320, I could probably tell you the difference between mp3 and lossless or mp3 and AAC almost every time. I've re-ripped CDs in AAC for my iPod and found that even on the earbuds that came with it (I'm pretty sure I got one of the better production runs,) music sounds a lot clearer and not muffled.

I had a friend who claimed that there was no audible difference between 320 mp3 and lossless. His rationale was that some computer magazine had sent out CDs with music in different bit rates and had readers compare them, and based on the results they declared that there were no audible differences. So to spite him, I had him set up a blind test for me that I aced with ease. I'm apparently very sensitive to the information that the mp3 codec strips out. I also agree that AAC is a far superior codec and, at least with earbuds or computer speakers, doesn't bother me at all.

Time to clarify this; it's $5k per cable.

I wandered around CES with an electrical engineer/audiophile once. It was very entertaining. He would look at the opened components on display and show me the actual audio path through the component. Then he'd point to other parts of the design, like a large bank of capacitors, and explain how they were a waste and could have no effect on the sound. We even visited a few cable manufacturers. He'd just shake his head and walk back out.

Gromit posted:

I'm of the opinion that $5k per component is a ridiculous sum to spend, and the law of diminishing returns kills you way before this price point.

I guess this is what I'm really asking. I'm sure that my tipping point for the law of diminishing returns is higher than most people here. The system I currently dream of owning (but will never be able to afford) would put me back about $35,000, and that's only for 2-channel digital. That's way beyond the tipping point, though, which I would peg at probably about $2000 per electronic component, and about $5000 for speakers.

What you're saying doesn't make sense to me. If you want an accurate reproduction of an instrument, the response curve of the microphone used to record said instrument should be flat and the response curve of the speakers you are listening to should also be flat. Why would you try to have the speakers emulate the response curve of your ear? That's irrelevant.

No, that's not what he's saying. The digital calibration shown was used to create a perfectly flat response at the listening position. Even a perfectly flat speaker response will not create a perfectly flat in-room response, thanks to boundary reinforcement, beaming, room modes, and other things. While digital calibration of bass frequencies to correct in-room response makes sense to some degree (and we could argue for days about how far it should be taken), doing so for the entire spectrum can create an incredibly harsh and unnatural sound.

The graph is just to show that a perfectly flat in-room response won't sound flat or natural.

It just seemed strange to read that interview where he seems to be saying that he'll spend whatever it takes to most accurately reproduce the experience of a theater, when top of the line theater projection and sound would be a maybe a 5th the price he's already paid if you had them spec'ed for 150-200 seat auditorium (it would be much cheaper for a smaller space). Hell, you could build a pimped out IMAX theater for less than he spent.

If you're going for absolute top-of-the-line, it's easy to blow past the $1,00,000 mark on a dedicated home theater, especially if you factor in design and construction. The goal is not to reproduce the theater experience, it's to outperform it in every way imaginable. If you have the money, it's worth paying to have it done right, since simple errors can really spoil the final result.

This guy definitely seems to miss the mark in a lot of regards, but I can respect the fun he's had getting to where he is. He literally has every product produced by one company over the last few years, and can easily swap pieces. I would have a ball toying with this, even though my choices in terms of which companies would definitely be different.

This would be sort of difficult though, as no home projection system or TV comes close to the resolution of a 35mm or even a digital projector (let alone an IMAX projector) that you would find at a theater.

A true cost-no-object home theater would use the exact same digital projection system you would see in the theater, with modifications made to make it suitable for home use. And the 2k standard used in the many (most?) theaters is only 2048 x 1080, which is only a negligible difference. This is set to change within the next year or two, as digital projection moves to 4k (some films are already being released and played at this resolution, but it's not particularly common).

So how much better does the million dollar ultimate audiophile system sound, assuming you spent the money on things that matter and not $5,000 HDMI cables or something?

Compared to your local movie theater? The difference is night and day. Commercial theaters are full of design compromises that seriously affect sound quality, but are almost necessary in a commercial venture. It's entirely within the realm of possibility for a commercial theater to have equivalent sound quality, but to do so in so large a space would be prohibitively expensive.

What would be fun, and what I have unfortunately not had the opportunity to do, is to compare the sound of some of these top-end theaters to the mixing rooms where the soundtracks were created. That would yield a lot more insight into the value of the home theater than a comparison to your local cineplex.

Be careful now, you're moving from audiophile madness to something which might be called science.

The home theater guys tend to be much more grounded in reality, mostly because the focus is on video, and video has objective standards that you can match -- standards that were created to assure that the produced picture matches the original intent. You don't really have the same thing for audio, especially 2-channel.

That's very true, but at least they're looking at the best-polished turd imaginable, right? This next year should be a really interesting one to watch in terms of price/performance, though. Runco's new LED-based DLP, for example, is apparently nothing short of amazing, albeit somewhat limited in terms of brightness and therefore screen size. Some very knowledgeable industry insiders have said it has the most film-like picture of any projector they've seen, regardless of price. It retails for only $15-18,000.

Sincerely, this is all bullshit. Even if these "effects" were all real, their impact in the final sound heard by a human would be absolutely 0.

Some of them are bullshit, yes. A lot of them are not. Speaker spikes can make a measurable and audible difference. Preamplifiers (and more specifically volume controls) can have a very measurable and audible effect. Speaker technologies obviously have a massive effect on final sound quality. Almost anything involving the physical playback of vinyl can have a measurable and audible sound difference. That video didn't just focus on fringe tweaks.

I'm not much into speakers, but I personally enjoy some good headphones.

A lot of the expense of high-end audio involves soundstaging, imaging, and room interactions, which ultimately are all intertwined, and are avoided by using headphones.

quote:

Amplifiers do make a difference.

You're going to need to be more specific here. Are you speaking about just an amplifier, or are you talking about an amplifier paired with some form of volume control? If it involves a volume control, of course you can hear a difference -- volume control is perhaps the most difficult part of the analog electronic chain to get right. If you're dealing with mismatched impedances, of course you're hearing a difference. If you're switching between solid state and tubes, you may be hearing a difference. But, assuming that the electronics are properly matched and capable of driving the speaker load without distorting, changing the amplifier should make the most negligible difference in sound quality. The difference, arguably, should be inaudible.

quote:

Any other fancy crap that isn't the headphone, the amp or the source (which doesn't make much difference if you have an amp, keep in mind) is complete and absolute bullshit. Unless there's a very specific function you need for something really relevant, these trinkets to improve the sound quality, "bring the details", "enrich your experience" or "reduce the micro-vibrations and the noise level from the omicron rays coming from the outer space" are absurd and I'm amazed people buy them.

Yes, some of it is bullshit, and a lot of it is not. The bags of marbles that sit on your components? Obviously laughable. Other things are not. Once again, using headphones eliminates a lot of these problems, but eliminates aspects of the presentation as well.

I've attended a good number of audio shows and I know a lot of audiophiles. I have a friend who owns a pair of Wilson Audio Alexandrias, which retail at well over $100,000. I don't know a single one who purchases expensive equipment merely because it is expensive. On the other hand, I have talked to many high-end dealers, though, who have said they have clients who come in wanting a new home theater, and the only requirement is that it be better than the one their friends just had put in. What I'm trying to say is that the people who purchase these things as 'jewelry' are generally not enthusiasts, or audiophiles for that matter.

Anyway, moving away from esoteric tweaks and into things that make a discernible difference in sound quality, here's a two-part interview with my favorite speaker designer, Richard Vandersteen, in which he discusses his new $45,000 pair of speakers. Richard is well-known for his adherence to a cost plus system for pricing his speakers, simply meaning that the retail price directly reflects the cost of building the speaker, and I've been told by a few dealers that the margins on his speakers are lower than the industry average. It's an interesting read for anyone who wants to see the kind of thought that goes into audio design.

There are 2 amps on the floor behind the speaker, and the speakers there have built-in amplifiers for their subwoofers. On the left side is the line stage with dual mono power supplies. On the right is the phono preamplifier, also with dual mono power supplies. The electronics are all from Aesthetix, and the turntable is from Clearaudio.

From the end of Part 1, speaking about the new midrange driver:

quote:

The only real problem with our resulting cones is the cost. The cones for the midrange driver cost something like $2000 a pair, which is basically an order of magnitude more than what otherwise-available, top-quality midrange drivers cost, with all subcomponents included.

That's not even for the full driver, just the cone. Place a 40% profit margin on that for the manufacturer and you come out at about $3300. Place a 40% margin on that for the dealer and you're up to about $5500 just for the midrange cones.

Well, here's the inside of the actual line stage box:



It's a true dual mono design, down to separate volume controls and power inputs for each channel. This is normally sold with a single power supply for both channels, but yes, dual power supplies are available. I make no claims as to whether this makes any audible or measurable difference, but placing the power supply (and more specifically, the transformer) as far from possible from the audio path is a good thing to do. An easy way to do this is to use a second box, like you see here.

I don't really care what people spend their money on, but it is crazy to claim that a custom $150,000 turntable is better than a technic 1200 ($300) for the sole reason that it reproduces the audio more accurately, as it is not the best way to do that.

A can't be better than B, because C is superior. That's faulty logic if I've ever heard it. While we're at it, CDs are poo poo because they're only 16-bit/44.1kHz. Anything short of 24/96 is obviously inferior, so why purchase a CD?

And yes, the $150,000 turntable is a luxury item. Nobody would ever claim otherwise. The system there represents a cost-no-object attempt at putting together the best sound possible, and anybody who attempts that understands that they'll be paying exorbitant amounts of money for very incremental improvements in sound quality. If they can afford it, and that's what they want to do with their money, then who cares?

And I'm not even get into the analog vs. digital debate. I currently don't own a turntable because I don't have the space to store records, but as soon as I do I plan to purchase one. Regardless of sound quality, I find playing vinyl to be a more enjoyable experience. There's more satisfaction (for me, at least) in setting a record, turning on a motor, and playing a record than there is in hitting the play button on a remote.

I think it fair, though, to suggest that buyers of these are after the bragging rights rather than the output?

First, I really wish that I did know his precise costs, because it would be fun to see precisely where the money goes. The audio world has plenty of gear with prices that in no way match their materials costs-- Lamm Industries and Wavac are two that come to mind-- but I see no reason to believe that this speaker isn't priced by the same cost plus method.

I also haven't had the chance to listen to the speaker in question, so I can't honestly comment on its value, but I have spent a considerable amount of time listening to the next model down, the 5A. It currently retails for $16,900, and if I could I would purchase a pair. Yes, this is already way past the tipping point of diminishing returns, and I freely admit that, but I personally see enough value in it that I would consider spending that much money.

Now, back to the quoted question. Yes, some buyers purchase ultra-expensive gear for bragging rights. Some purchase it because they're wealthy enough that they purchase the best of everything and just happen to want a stereo. Others purchase it because they want the best sound possible. I really don't think that many people purchase based on bragging rights. First, who are you going to brag to? People on the internet? Other audiophiles? High-end audio generally isn't "conspicuous consumption" in the same way that, say, a porsche or a boat is. The general public doesn't care about sound reproduction enough. It's quite possible that Joe Average would be more impressed if you blew your money on that "really cool Bose system with the tiny cubes."

If you ask me, the real division between audiophiles is best shown by their music purchasing habits vs. their gear purchasing habits. If you're talking to somebody who has blindly swapped cables/amps/speakers 5 times in the last month based on what somebody over on audiogon suggested but hasn't bought new music in the last 3 years, and instead listens to the same 5 reference discs over and over while he moves his speakers 1/32" of an inch at a time, just walk away. They've clearly lost track of the purpose of the hobby, and I would argue are the people most likely to purchase expensive gear simply because it is expensive. On the other hand, if you're talking to a guy who's constantly searching for new, great sounding music, has a well-set-up system, and changes components when he feels that the change makes a significant difference, you've found a quality audiophile.

Oddly enough, the almost-deaf guy I know absolutely falls into the second camp.

Ok, the B&W to Sasha was huge, the C500T to the REX was huge, this rack may take the crown as the single most improvement of one component and they aren't done with what they can do according to the manual. I got the Critical Mass Systems Platinum racks in today. It warns you that upon first putting them together that they will sound listenable and ok but they will change undeniably over the next 300 hours or so and at times may not be listenable during this time. Well at first listen it was astounding the difference. The stage was definitely more transparent. The biggest thing I got right away was the bottom end got even better which I had no problem with the bottom before, thought it was as good as I had heard, then the "ch", the "T" and the "S" of everything had a chhht or a tee' or a sssts to it so to speak that I'm not sure I heard anywhere else ever before so nice except in Glenn Poors Audio when I heard the Sasha for the first time and the equipment was on Critical Mass System Racks. This is one of the things that made me sell my entire system was the explanation point on everything. The BAT stuff over the Mcintosh and Wilson Sasha over the B&W got me somewhat there but this rack is the final piece to the puzzle of sound. I'm just at the beginning the break in which they say is a good chance to listen now but be prepared for it to change for the better or the worse over the next 300 hours till it settles in. In the bass guitar I hear more of the upper frequency rattle of strumming a bass guitar. Its very hard to explain but everything just got naturally beautiful even more so. My pre is tube and my amps are solid state but these racks just made it as good and airy but more natural than any tube sound and the emphasis of the above is more so than I think I've ever heard in any sound system ever but if you hear it live you do hear that stuff. If this stays as it is or gets even better then this will be the best $17k I've spent for sure. I tried to explain this to and you will have to forgive me as I know you don't know me that well but my audio buddies know I'm not so brite and I don't know the audio terms a lot of people know but I do know what and how to listen and I'm telling you that these racks made an immediate improvement over my previous racks and to explain it is hard for me but to hear it is easy.

That's right. 300 hours to break in an audio rack. A $17,000 audio rack. That he considers to be a more significant change in sound than switching brands of speakers.

I have no problem defending a lot of the things in the audiophile world, but this one is beyond me.

This is one reason, I think, that there are so many new high-end DACs on the market now. It lets the companies avoid the issue altogether.

Modifying the power supply and analog outputs of a blue ray player isn't going to make a difference in quality unless those parts were marginal to start with (and I mean "barely works"). Especially not for a 1900% price increase. Who the hell uses analog outputs with Blu-Ray, anyways?

The Oppo was a universal player, so audiophiles who wanted CD, DVD-A and SACD in one unit.

Do you want to hear "the music as the artists heard it in the studio"?

Well, cough up £50,000 for a Linn Exakt system, then!

As near as I can tell (and Linn's marketing has been terrible), this is little more than a network player with a digital link to speakers with built in amplifiers.

Honestly, in terms of "lifestyle" systems, the idea makes sense (but not at their price). An attractive networked box that can pull data from your computer/tablet/phone and play it directly to speakers without any middle ground components is a good thing.

It will never catch on with audiophiles, though, because it eliminates the neurotic gear swapping.

I found this interesting. It's from whatsbestforum in a thread about an $8,400 power cable.

The author is the owner and lead designer of Atma-Sphere Music Systems.

quote:

If you want to know what power cords work, I can explain that. the principle is different from why power conditioners work.

Almost any amplifier or preamp has a power supply consisting of transformer, rectifiers and filter capacitors. Once the caps are fully charged, they don't discharge a whole lot between peaks of the AC waveform, where they get replenished. The rectifiers will only conduct (commutate) when the filter cap voltage is lower than that of the power transformer. So in essence, the rectifiers are only conducting on peaks of the AC waveform, and then only for brief periods of time.

This means that the power cord has to have some bandwidth (since the rectifiers may only be on for a few milliseconds, that means its a high frequency, despite being repeated 60 times a second) or the delivery of current will be curtailed. In addition, it should not have much in the way of a voltage drop either. I have seen a 2 volt drop on a power cord result in about a 30% loss of output power in a large power amp. Tell me you can't hear that- it was measurable with a simple DVM!!

Many will argue about the effects of the wire in the walls and what not. They are right. The wire in the walls makes a difference, but it so happens that ROMEX has pretty good HF response, so no worries. But if you live in an older building where the wiring is not up to code, you may find that you don't hear the effects of some highly revered cables. Its not their fault, its yours- fix the building wiring and the power cables will become more audible. That will be a good thing BTW.

In a preamp the effect of the cable might be less audible, especially if the preamp has a lot of regulation in its supplies, but otherwise the same principle still applies.

A weakness of power strips and inferior power conditioners is that they force you to use a common power cord for the entire system. IOW, the power cord for a power strip or power conditioner had better be pretty beefy, with good HF response in such cases. YMMV, as there are a variety of variables, but in a nutshell this is why power cords make a difference. Its simple physics y'all.

Do you have to spend a lot of money to get the best power cord? I don't think so. What is important is the overall current handling ability, and good HF response. That does not have to cost that much- its a matter of how the cable is built.

I don't have the EE background to qualify what he's saying, but it echoes my personal view on power cables, etc., which is basically that they only make an audible difference when they're physically deficient. In other words, if you hear a measurable difference one of the two cables is basically broken.

What is very entertaining is how much hate he got from other people for making this post. It's apparently sacrilege to try and measure things to determine why you can hear a difference.

Now you guys have got me curious about measuring the phase and frequency response effects of the presets and the graphic in iTunes. For gently caress's sake.

Post the results if you do. I'm honestly curious.

I spent last night toying with a Fisher console stereo from 1963. Apparently I'll be inheriting it from my grandma when the time comes. The cabinetry is in great shape, but the electronics are going to need some work, and the foam surrounds for the speaker drivers are obviously dead, given their age. The biggest thing for me will be figuring out how to get rid of the nasty 60 hertz hum.

In the end, it should make a nice piece for our master bedroom.

Is the high end audio industry growing with rampant increases in wealth inequality or was it hit hard by the recession? I have a friend who is interviewing with a botique gear distributor and I can't decide whether to tell him its a silly industry or to take those suckers all the way to the bank.

From what I can gather, the high-end market is shrinking in the US, together with the shrinking of the middle class. It's one of the reasons why prices are skyrocketing, as companies move to target the 1% exclusively. The real growth is in Asia, where newly-minted millionaires and billionaires are looking to spend their money as conspicuously as possible. Exceptionally expensive equipment (the Naim Statement amp comes to mind) are basically built with the idea that they will sell less than 10 total, and all in Asia, but the markup is so insane that it will be profitable for the company.

I borrow interesting records from my city's library and rip them as FLAC. I'm pretty sure that the audio quality is same as spotify premium's, but they FEEL better oh god im the audiophile

As a member of the audiophile industry, I can tell you that the surest way to piss off an audiophile is to tell them that Diana Krall is the best artist in the history of all music.

Does anyone actually listen to Diana Krall outside of audio shows? I mean, if somebody walks into the room and asks you to put on Diana Krall, they've basically admitted that they have no taste.

There's a guy I see at Rocky Mountain Audio Fest each year who goes from room to room listening to the same German metal song. And I mean it's the same song every single year. I haven't been able to decide if he's the world's best audiophile troll or if he's really spending thousands of dollars to improve the sound quality of dynamically compressed screaming.

I just got back from the show at Newport, and everyone and their brother was playing Stevie Ray Vaughan ad nauseum. Some guys come in to the room and have a CD that they absolutely have to hear immediately. There's a mix between Jazz purists and people who just want to hear something with a good mix. For all the bullshit, listening to "Superstition" on a $500k system did sound pretty incredible.

That beats RMAF two years ago. Nothing but K.D. Lang's Hallelujah, over and over again.

Found this gem in a thread about audio playback advances from the last 25 years:

quote:

The more we learnt, the more we discover how much we don't yet know....

- Magnetic field and how it affects sound reproduction application.
- physical changes in optical disc media after each successive spin/read in a transport/ player.
- physical changes on the surface of various disc media after coming in contact with other materials and how it subsequently affect sound reproduction application.
- dynamic compression & RF pollution, and why more audiophiles prefer them, subconsciously.

I don't even know where to begin with this one.

That was an interesting read! Shatters my preconceptions about FLAC! How about if I bought albums directly from say HDtracks, they must sound better right? Or its very possible to that HD audio is a lie.

Some of the HDTrack releases have better-sounding mixes than what you would find on the CD or iTunes, but as near as I can tell there is no way to figure out which tracks do and which tracks don't.

I can't think of a better thread to ask about this.

I was just on a headphone review site and saw an ad for the Capital Audio Fest in DC. Has anyone here been to their previous events? It's $20 to get in and I'm on the fence about going. I'm not in the market for any super high end audio but it'd be fun to hear some crazy setups.

Capital Audio Fest is a pretty small show, both in the number of rooms and the attendance numbers. The small number of rooms is kind of a letdown, but the low attendance numbers means that if you like something, you can generally listen for a long time without bothering anybody. The size of the show seems to keep away the really big players, although to me this is almost a plus. You likely won't see the obscenely expensive gear that you would at T.H.E. Show or RMAF, but the owners and designers you'll meet are usually very personable and open to questions/discussions.

Looking at the exhibitor list, there are a few rooms that would be pretty interesting. Audio Note UK can be a good listen if the presenter is willing to have fun with the music (they sometimes have a guy who seems a tad too preoccupied with "audiophile-quality" classical music). The Classic Audio room is always a blast. I recall almost always hearing great classic rock from their rooms, with prodigious amounts of very good bass. I personally would enjoy the Zu Audio room, but I'm biased, since I own a pair and they're a local company.

For $10 it would be a no brainer. For $20, it's a bit tougher, but to me it would be worth it. Shows are the best way to hear a lot of systems back to back, which makes it easy to determine what kind of sound you like, and what kind of sound you absolutely want to avoid in the future. It only took a few hours attending my first show to determine that I hate sibilance, generally dislike horns, and am better off avoiding ribbon tweeters.

There was a guy on avsforum who had one of those installed a number of years back. He had also excavated under his garage's foundation to build his theatre, so over-the-top was kind of his thing. He said that when he had it all the way up the first time, he had a few neighbors wondering if there was an earthquake.
