Eh, its more fun to troll the crazies into the open on a non-audiophile forum. Ask for setup advice somewhere you would expect decent discussion, and in your existing spec, itemize a $0.50 kettle cord or something.

Wait for people audiophiles to pop in and give you the weakest link spiel

Here we go again. Another audiophile-infested forum with users who are so deeply-set in their crazy woo-woo beliefs that every single thread I participate in with relevant advice eventually turns into personal attacks against me.


For context, the discussion was about a user asking for amplifier recommendations for a specific set of speakers. I dared to suggest a couple of decent budget options with adequate power, but apparently the audiophiles took offense to that and insisted that 1) 100+W is absolutely necessary even if you only ever use ~10W (100dB on a 90dB/1W@1m speaker), and 2) the more fancy-looking and expensive your amp is, the better it sounds.

I countered with ABX tests, they started getting personal.

AAC-HE is effectively your best (only?) option for ultralow bitrates and most AAC encoders are about the same, so you may as well let iTunes do it. That's if your 4Gb iPod supports it, which it may not. What is the actual model?

I think it's a 2nd gen Nano? Bought it in '07 or thereabouts. I've never actually used iTunes, the first thing I did with my Nano was load some app on it that gave me a custom interface so I could just drag files over to it like a USB stick. When I decided Vorbis was the file format for me I moved over to RockBox and it's been running that for the last 5 years or so. There must be a way for foobar to encode AAC, I'll experiment with that and see if I can find a sweet spot where the sound quality is relatively transparent over crappy earbuds.

Have you ever wanted a $13,000 DAC? No? Well apparently enough do for Playback Designs to sell one. It has a big stupid remote control even though the only thing it has to do is receive bits and spit out an analog signal. My $150 Schiit DAC only has a button to switch input modes--why would you need anything more for a DAC?

quote:

The next logical step in the Playback Designs' line of products is the release of the Music Playback Digital to Analog Converter 5, also known as the MPD-5. The Playback Designs MPD-5 is identical in every way to the MPS-5 SACD / CD Player except it does not have a transport mechanism. Also, thanks to the modular nature of its design, the MPD-5 can be upgraded to a fully functional MPS-5 CD / SACD Player. The MPD-5 is a world class DAC that can receive a variety of external digital sources, including PC based music servers – not only a unique and powerful combination, but also versatile in applications.
Why don't they just call it a "disc drive"?

quote:

Audio is represented in a y/x-axis system: the y-axis for amplitude and the x-axis for time. Mostly because of analog audio's sensitivity problems in the y-axis, digital audio was introduced. But digital audio not only quantizes the y-axis, it does so as well on the x-axis. Sounds like we got more than we wanted - true and too bad. A typical state-of-the-art DAC converts between quantization levels in the digital y-axis and the analog y-axis and is completely transparent and open as to what happens on the x-axis (time domain). Sounds like we forgot the quantization on the x-axis.

This oversight forced us to treat digital audio signals as if they were analog: use special cables, use all kinds of mechanical devices for our CD players, power conditioners for digital audio etc. Looks like we just shifted the original problem from the y- axis to the x-axis, but the issues are still the same. Instead of interference or crosstalk we now call it clock jitter.

Almost all DACs available today deal with the y-axis only and rely on external devices for the x-axis, such as complicated master/slave clock arrangements or external sync clock generators. At best these devices are band-aids on a wide open wound deep inside the DAC. They help, but do not resolve the problem at the source. We need a 2-dimensional DAC that not only works on the y-axis, but also on the x-axis. With this we can separate the digital world completely from the analog one and render any digital cable, transmission format, storage media and application completely irrelevant to the final sonic performance. The only analog problem that we still have then is the separation of the power supplies for digital and analog.

The DAC inside the Playback Designs product line does exactly that: clock jitter from incoming digital audio signals can be described as an analog signal that gets mixed together with a quantized digital signal (our ideal and constant sample rate clock). So before any processing can happen we need to bring these 2 components into the same domain: The Playback Designs system quantizes the clock jitter into a digital signal, where it then can be subtracted from the original sample rate while the latter is converted to analog at the same time. Of the course, the DAC also works independently in the y-axis by using a set of unique algorithms in a completely discrete architecture (not even a single Op-Amp is used).

Tests have shown that the DAC inside the Playback Designs product line can be fed by any digital source including a PC, an inexpensive Discman, a DVD player, or high-end CD transport and none of them seem to make a difference on the sonic performance of the analog output signal. Ultimately this means that as long as you are sending our DAC truthful complete bits the source does not make a difference. We believe if you own a home computer, you already own a music server that cannot be sonically bettered!
:psyduck:
Does a Discman even have an SPDIF output?

And now for one of my favorite audiophile products, Koetsu low-output cartridges. Good cartridges can be expensive, but not the price of a new car. Koetsu is infamous for making the casings of their higher-end cartridges out of exotic natural materials to raise the markup make the owner feel rich improve the sound quality. I would not be surprised if they made cartridges that are illegal to import into the US because they contain ivory.

Choice quote:

quote:

Koetsu owners decorate their homes with originals, not prints. They smoke Cubans rather than Swisher Sweets. They drink single malt. They favor vinyl to CDs, and their systems sound better than their buddies'. Koetsu owners require the best. And they know the difference. In the 1970s, Yosiaki Sugano, a renaissance man who'd had success as an artist, musician, swordsman, calligrapher and business executive, became the creator of the world's most renowned phono cartridges.
By an rear end in a top hat, for assholes. Their most expensive model on the site costs $18,500 and comes with a diamond cantilever. God help you if you fumble with the tonearm or touch it very slightly too hard with the stylus brush.

But in the end, it doesn't matter, because for the truly rich audiophile, as with all forms of 1% consumption, the waste is part of the appeal. You are extremely rich, and you derive pleasure from destroying quantities of capital that workers would sell their organs for.

Inside your computer are millions of little bits.
Each one of those bits can be a one or a zero and as your computer
runs programs each one of these bits changes its state, often
thousands of times every second.

Understandably, this puts a lot of pressure on your bits and,
after a period of time, some of your bits may start to wear out.
At first your bits become a little bit cranky and don't change
quite as quickly and after much use they may become worn out on
the edges.

The Bit Recycler is designed to reconstitute your bits, making
sure that your bits are always in top shape.

When you first run the Bit Recycler, the title screen will appear.
The first thing to do is to select "Analyse Bits" from the Run
Menu. The Bit Recycler will proceed to analyse your bits and
determine their average state of health. When analysis has
completed you will be presented with a report. If the report
recommends bit recycling then choose "Recycle" from the Run menu.

Bit Recycling has three stages. First, your worn out bits are ground
up into a sort of bit 'mush'. The bit mush is then boiled and poured
on to a conveyor belt where finally, brand new bits are stamped out.

Bit Recycling is a maintainence operation which should be performed
at least once a month. This will normally substitute for the old-
fashioned way of recycling your bits. Somewhere inside your computer,
usually tucked away beside the hard drive, there is a little container
called the 'Bit Bucket'. Worn out bits usually accumulate in the
Bit Bucket. For manual recycling, bring your computer to a trained
Bit Recycling Technician. He will remove the Bit Bucket and pour
the worn out bits into a little spout on the back of your computer
where they will be reprocessed.

* NOTE: Do not attempt manual bit recycling yourself.
The above description of manual recycling is a
simplified outline of an inherently complex and technical
operation. Use the TOGGLE BOOLEANS Bit Recycler instead or
consult a trained technician. TOGGLE BOOLEANS will not
be responsible, in any way whatsoever, for any damage
or data loss caused by the use of the Bit Recycler
or following these intructions.

Version 1.2 also add the ability to detect and execute subversive
elements among your bits. Sometimes when bits are worked too
hard they become revolutionary. If your Ones are being worked
harder than your Zeros, the Ones begin to feel like they are being
exploited and if there is strong leader among them, they can
rampage through your computer trying to turn all of the Zeros they
find into Ones.
This can cause great havoc for the computer user, so it is important
to ocassionally discipline or execute these subversive elements.
To do so, select Execute Subversive Bits from the Run menu after
Bit Analysis has completed.

"Transport" is audio/video engineering jargon for the part of a media player/recorder that's responsible for getting the signal off of/onto the medium (not just optical media, things like tapes too). It's not just audiophile bullshit—calling the CD transport a "disc drive" would be legitimately odd in this context.

It's not like playing an instrument where a bit is plucking a string, or whatever. There are a certain number of bits that make up a second of audio (prenegotiated between the devices). As long as they arrive in the right order and you aren't missing any, the exact timing really doesn't matter beyond making sure they don't take longer than the buffer on the receiving end (because then you'll "run out" of sound to play and the music will cut out.)

The part where timing has to be accurate (or at least consistent) is in the encode and decode. If you have a "drifting" clock, the encoder may think that a stable analog input of, say 900hz is 890hz one second and 910hz the next second.

So that's what I was saying - they just assume a fixed amount of time per sample.

That being said, a drifting clock would yield a hideous amount of pitch variation that would be hard to miss. The reason for a master clock in recording is purely because every device has a little difference in clock so a master clock keeping everyone in sync is a good idea. On playback I can't imagine it matters much.

From a review of the Sennheiser HD 650 headphones:

quote:

It's very good for pipe organ, easily reproducing all of the 16 foot ranks. 32 foot ranks sound very good, but you won't quite hear all of the Cs and Ds — but very few things can reproduce sub-20 cycle notes like these.

Isn't that like the sort of poo poo you need transmission line speakers or subwoofers with multi-kilowatt class D amps to reproduce (assuming you actually have a recording that contains any), and a big room for it to fill to give you the bone-rattling effect? Why even talk about that in a headphone review? Headphones do not, cannot, and should not reproduce infrasound, end of story.

I don't think it's that cans can't produce 16 Hz (especially given the small volume of air they have to pressurize), it's more that infrasonics are perceived more with your body than your ears.
