Is the color in the amp , the preamp, the souce?

I'm sure I have seen this discussed at different points in time, but seeing that I just bought a new for me 5 channel ATI 1505, it got me wondering again, especially when I read this can be a "Cool" sounding amp.

Sorry in advance if I am ignorant on this subject, I am trying to learn. If I don't ask, how will I know???

My interpretation was that power amps were supposed to simply amplify the sound, with the better amps having lower distortion and higher actual power. I also understood the more neutral the amp the better. Now I realize tube amps are a different animal altogether, so my focus is on solid state only here.

Would it not be preferable to add any coloration (if one so chooses), warm, cool, what have you via the source and/or the preamp? This being said, and if true... what makes say a Bryston, Krell, Mac, or any multitude of expensive amps better, all things being equal? Let's say all the amps we are considering all put the same #'s up, same wattage, same low distortion, and they all use a large torroidal transformer, so they all have plenty off juice. Would you get seriously different sound if all the other components were the same, and if so Why? Obviously differing the power changes things, but lets go hypothetical here for comparison sake.
I have a hard time understanding (all specifications being equal) how an amplifier can sound different. Isn't all the signal processing done in the pre, the source, or both?

Again, sorry for my ignorance. Sometimes a little knowledge is more dangerous than none :)

I agree with your basic premise. I've always attempted that the Power Amp should primarily be matched to the requirements of the speaker, and, it should be as close to a "neutral" sound as possible. of course "Neutral" is in the ear of the listener.

I then have tailored the overall system character by using specific upstream gear, primarily Preamp and Interconnects.

I myself lean toward large solid state power amps driving in my case my long time preference of Planar speakers.

I then dial in the overall sound with a "CJ or CJ Like" tube based preamp and of course cables.

Obviously, depending on the power amp's "neutral-ness" or lack thereof, upstream choices are affected.

Once I become very familiar with the preamp/poweramp/speakers overall sound, it's pretty easy to experiment with source gear and determine how a given DAC/CDPlayer etc. affects the "base" system sound provided by the preamp/poweramp/speakers combo.

Just my 2cents, YMMV, Don't try this at home, yadda yadda yadda.
