Does anyone know of a good SQ amp that can put out 150-200 RMS X 4?

You wouldn't gain any power over your current amp, so why switch?

Something with over 100 S/N ratio

You are not going to hear a difference between S/N ratio of, say, 80 and one of 100.

That's an arbitrary # that really has no correlation to audible results.

Over rated spec. Any amp worth owning is going to have an acceptable SNR.

, and low THD?

Your amplifier does not have a THD higher than 1% @ rated power, so there's no point in switching amplifiers due to THD as you will not hear any improvement.

Damping factor > 500?

Another over rated spec. You are not going to hear a difference between an amplifier with a DF of 50 and one with a DF of 500.

Do not buy a new amp with the intention of changing or improving the "sound quality" of your stereo unless your current amplifier is broken/etc. If you are going to buy new amps, at least have a legitimate reason; size, power, features, cosmetics/aesthetics. "Sound quality" is not a legitimate or intelligent reason.

Can I parasitize this thread a bit? I am looking for the same thing, but in my case I can go up to 700 USD if I have to. One pair of channels can also have lower rating, to feed my tweeters.

I don't know if Kicker qualifies as SQ, but their 08ZX800.4 might be close to what you are looking for, they don't publish all usable data, as is so common, and I am yet to see damping over 500.

because having bought a few Critical Mass speakers, I notice that the amps they sell (all of which are several thousand dollars) are really low THD, 100+ S/N ratio, and high damping factor.

100% Marketing.

So I went around looking at most amps, and every single one I looked up (including most budget amps) have a S/N ratio of over 90, and a THD of 1% or less.
Does that mean you can pretty much go cheap on the amp, as long as it has the power you need, and still not lose any SQ?

So basically the only things that you would want to fork over good cash for SQ wise would be the speakers/subs?

pretty much //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

but it depends on who you ask actually, some might believe that amps have a certain sound to them. Some people don't.
