I understand what a pre-amp does but I don't understand why you'd need them in a regular home audio setup. Note: I am not talking about a phono pre-amp, just a regular pre-amp.

For example, if I have a stereo receiver, why would I ever need a pre-amp? I am asking because I often hear people talk about needing them in their setups. I just don't understand why.

Think of it as a volume control for a strictly defined "power amp" without any real adjustments, versus an "integrated amp" or receiver with volume and other controls built in.

Oh, I didn't realize they made amps without volume controls. I guess that makes sense why amps with volume adjustments are called "integrated" amps. Thanks.

Think of a receiver as a pre-amp and amp in one box. Some choose to have a single box. Some choose to have a preamp in one box and amps in separate boxes. The separate setup allows for flexibility in the form of scaling up power as needed, swapping out gear, upgrading etc. Most people don't need to concern themselves with all of that. Separate setups are for people that like to tinker, kind of like jail breaking a phone.

Does anyone actually use HD radio? I actually listen to a lot of terrestrial radio, and my favorite station has an HD feed. If there's a significant improvement in fidelity, I wouldn't mind picking up a component receiver.

I can't find many options besides car head units, though. The best thing I see is a Coby for $50 on Amazon, but Coby doesn't scream, "quality" to me

My JVC car stereo does HD and side by side the HD is noticeably cleaner.

Ok, might be a dumb question that was covered a few pages back but I can't tell. I'd like multi-zone, whole house audio, but my house is not wired for speakers. It would be a massive pain to do the wiring, so I'm curious as to whether there are wireless speakers, maybe bluetooth maybe something else, that I could "wire" into like a 6-zone amp. I'm not interested in streaming music from my phone, I want to play cd's or records to my amp and turn on/turn off zones, control volumes independently, etc... The speakers could be flushmount or not, really. I know getting power would be an issue, so I'm assuming that flushmount would be weird, but it would still be easier to wire a speaker for power in the ceiling or wall than to run conduit back to my amp. Any suggestions would be awesome.

You shouldn't need to run conduit. If you can wall fish romex for power, wall fishing speaker wire is easier.

A well set up stereo system beats all non-headphone alternatives for music listening. You'll get it cheaper, installation is easier and it'll sound better. I've never met anyone who bothers with records and is content with multiroom speakers. Not saying such a person couldn't exist, I've just never met a serious hobbyist who doesn't want to sit in his listening chair while the record plays.

That said, you could try something from http://www.audiopro.com/ . They're not the cheapest but they're not terrible, either.

It's finished. Actually re-wiring my house for sound is way down on the list of things I want to do with my weekends. I'd rather just move a boombox from one room to another.

Somebody needs to invent a little dongle with speaker wires on one end that acts like a virtual wire. Plug one into the receiver, the pair into the speaker, and there it is.

This is basically sonos connect and sonos connect amp.

It's really expensive and some people hate using the app. But multi zone, individual volume controls via software, etc. Has a line in for outside components. I'm sure there are better and cheaper ways but it can be done and in your case I'm not entirely sure how it would work with the line in. It is intended to be controlled through a computer which I think goes against what you're trying to do.

If your receiver has pre-amp out on its zone 2, wireless speakers exist, but range, fidelity and cost won't be ideal.

Audio is a lot easier to beam around the house if you let go of the physical media. Rip the files and quit trying to make the whole house center around your receiver? There are a few more options once wifi is involved.

I just looked at our setup. I think Sonos may work. You can take the line in for any device and group it with any other device(s). So if you had a Sonos connect hooked up to your stereo via line in you could wirelessly beam that around to any other zone. Volume controlled in app, but playback controls would still be via your stereo.

I use a Lepai 2020 Tripath amp for my desktop setup. At the lowest volumes, only the left channel has output. In order to play really low volume through left and right, I have to decrease the volume in either the application or Windows, and then turn the amp up.

Why is this? I imagine the answer is "because it's a $25 amp" but really, why is this? What causes it?

Cheap potentiometers (the volume knob) exhibit their cheapness in channel imbalances.

If the pot varies by 5% between left and right, you're most likely to notice at low volumes because the pot is at the high end of its resistance. At higher volumes, the pot is "working less," so the variance matters less.

Nice pots like the Alps used in a lot of mid-priced gear cost about as much as your amp. Crazy expensive gear uses stepped attenuators where each step is matched by hand.

Cool, thanks. I've seen potentiometer mods mentioned with this amp. Aside from the low volume fix, what other affect would it have?

Most amps like that operate at a fixed gain and just throw a pot right before the output as a volume control.

Should be a simple swap as long as you get the same value and pay attention to whether the original is a linear or logarithmic. (it's probably log, also known as an "audio taper")

I don't know if this is the right thread, but there seems to be no dedicated thread to PC Audio:

I'm discovering a very strange problem with stereo audio. I record a song off youtube, lets say. I play it on the same computer and it sounds fine. I take it over to another computer and play it, and its all garbled and low and you can barely hear it. On that same computer where the problem is happening, I use an audio editing program to play only the left channel, and suddenly it sounds fine (but coming out of one channel). I do the same an isolate the right channel, and it sounds fine (but coming out of the right channel only). The STRANGEST thing is that if I copy just the left or right channel, and then paste it onto the other channel (duplicating one channel onto the other) it works just fine in stereo. I cannot for the life me understand what is going on.

I think Tivoli audio makes some, but honestly, your best bet for a "demure" looking system would be to just pick up a receiver with that capability and plug some bookshelf speakers into it. I'm sure there are others out there too but all of the ones I can think of look flashy/gimmicky.

What kind of devices are you planning to play music from? If you're using iOS devices or iTunes as your PC music player then you can easily get a used Airport Express for like 60 bucks (or a refurb from Apple for $75) and plug that into any stereo you want for easy connection over your home wifi network.

I have one plugged into the Aux. feed of my '70s receiver and it works stupid well.

The Wirecutter did a review of these and they liked the Logitech UE Mini Boom. It's small, runs on batteries for a long time, and sounds decent. The Jawbone Jambox looks "nicer" (depending on what you think is nice) but doesn't necessarily sound as good.

I looked at some of their other suggestions and the Bose SoundLink Mini actually might be the best choice if you care about tasteful design. Even though Bose is shunned by most people in the stereo world, it apparently has good sound for what it is. $200 though.

If you want to use whatever stereo, maybe just get a Bluetooth receiver? I linked a few a while back here, might be better stuff now, but whatever the case there's a bunch.

I've read through this thread and have some semi-answers to my question.

I may be getting a stereo receiver of my choice for Christmas and want to pick the right one. I want one with an FM receiver and need to run a turntable, laptop, and ipod/iphone through it. I have a pair of Klipsch KG 1.5s. I'm not interested in surround sound, I don't have a TV, no bluetooth or XM, and I'm not trying to do a home theater. I just want good solid sound from a 2-channel system. My limit is ~$300 - 350.

I've narrowed my search down to: Harman Kardon HK3390 or HK3490, Pioneer SX-A9-J, Onkyo TXZ-8255

Which of these is best or what are some similar alternatives of excellent quality?

edit: While I would like to go vintage myself, I don't want to send the gifter on a really irritating errand. So I'm after a modern system for now.

Out of those I'd go with HK3490. Good phono stage, inbuilt DAC and decent price. Haven't heard the Pioneer one, HK3390 lacks the DAC and isn't that much cheaper, Onkyo also lacks DAC and the model you're looking at is one notch below HK3490 anyway.

Preface: I'm not an audiophile per se, so some of this is a little beyond me. I'm a little new to this level of gear collection.

Would a receiver without a DAC not drive my speakers? Would I need to get a separate amplifier to pair with a receiver without a DAC? I was under the impression that these receivers had sufficient power without a separate amp.

I see now that I would not need a separate amp. My revised question: what advantage or necessity does a receiver with an inboard DAC have over one without?

DAC is a Digital-Analog Converter. In simple terms it means you can use optical out for connecting your laptop instead of 3,5mm to RCA.

All receivers in your list provide enough power to drive your speakers without any extra purchases.

Using optical out bypasses the DAC in your sound card which is useful if you get a lot of interference (ie. noise) especially at high volumes.

You're too fast for me. Thanks.

New question, since I was planning on running my computer through a 3.5mm to RCA: Does an optical out carry better sound quality?

Sorry for what I assume are really basic questions, I'll keep on doing my own research and try not to bog this thread down.

Can someone recommend a good usb mic with a flat response? I'm pretty sure the onboard sound on my PC is toast (which is fine - I have a DAC), but I'd like to be able to calibrate my system. I don't have a huge budget, so I'm not looking for a $900 studio-grade Audio Technica, or anything. <50 bucks, maybe?

I'd like a condenser mic, but most of the ones I'm seeing are cardioid, and I assume omni would be better for this.

Edit:

Something like this would be perfect... if it wasn't 80 bucks.

Parts express has some calibrated mics. I can't remember off hand which ones are the best but I believe they're around $40. Soundcard doesn't need to be perfectly flat because you do a loopback response and then your program creates a calibration file for it.

Best place to ask is on the Room EQ Wizard subforum over at home theater shack forums.

It's not that the soundcard isn't flat. It's that the soundcard is broken - as in it doesn't recognize anything I plug into any of the ports. I've tried several different drivers, and I'm pretty sure it's busted.

I'll check out the home theater shack. Thanks

That subwoofer has speaker-level inputs, but inconveniently, not outputs. You could run speaker wire from the Speaker A terminals to the speakers, and from the Speaker B terminals to the subwoofer. Then you'd have to have both Speaker A and Speaker B outputs turned on to use the sub.

If it's not too late to return the TX-8255, you could try the Onkyo TX-8020, which has a preamp output for a subwoofer: http://www.amazon.com/Onkyo-TX8020-TX-8020-Stereo-Receiver/dp/B00EE18O7W/ref=sr_1_2?ie=UTF8&qid=1386425074&sr=8-2&keywords=tx-8255
