How big of a difference do amps make?

Very nice! You are correct. Guess i should have been a little clearer on the title.
Any valuble advice on how much changing amps can impact system?

Almost as big a difference as Pangea powercords

the source makes the most difference 'cuz if the source does not create the sound, the downstream components are sure not going to amplify them! so, i would 1st spend money on your source, get it to where you feel comfortable money-wise & sound-wise & then spend the money on pre & power. buying superb amps before having a source that can take advantage of it would be putting the cart before the horse. IMHO. FWIW.

Crucial.

I think they are every bit as important as speakers, the best speakers in the world just let you hear what your amp sounds like.
I'd rather have a $200 used pr of KEF standmounters with a 10K amp than other way around.
