Importance of Amplifier versus Preamp?

"I see. I always thought it was the amp not driving the speakers properly, and that the amp was introducing its own set of colorations."

That's true, as well. But for the purposes of this discussion as to how important the preamp is, we're assuming the amp in question is getting the basics right. I can't speak for anyone else, but I made that qualification in my first post. It was actually the first thing I said.

Assuming your power amp has no trouble driving your speakers and it doesn't do anything really bad sonically, I would say that the preamp is easily more important."

So the basis for my discussion begins with an amp that is sufficient enough to get the basics right. Actually, now that we are looking at this again, all the components need to get the basics right. If you have a bad or mismatched component, it can ruin the sound of the whole system, regardless of how good the other components are. Sorry if there was any confusion on that point. Hopefully, my comments make a bit more sense now.

Gentlemen, there have been lots of interesting responses, but may I point out the possibility, especially given the first sentence of the OP's initial post in the thread ("New in the field"), that the OP may not have presented his question as optimally as possible.

It seems to me that what he is really trying to determine, with respect to his main system (and in addition to the recent question about bookshelf speakers for a second system), is what can he do for $1500 to best upgrade the specific equipment he presently has.

It seems to me that many of the 70 responses posted so far, while of academic and theoretical interest, are too general in nature to be of any practical value in this specific case.

Al, would you prefer members simply tell the OP to buy x, y, z preamp or
power amp? No one outside the OP can possibly know what will work best
in his system, or what will give the best bang for his buck. Nothing short of
a home audition of a component is going to prove anything one way or the
other. All any member here can do is share there own view which should
atleast help steer the OP in the right direction. Then again, he might simply
find the many contributions of academic and theoretical interest only as you
postulated..

That's true, as well. But for the purposes of this discussion as to how important the preamp is, we're assuming the amp in question is getting the basics right. I can't speak for anyone else, but I made that qualification in my first post. It was actually the first thing I said.

Ok, thanks for your reply. That's true, you made that clear from the get go. I was just relaying my thoughts and experiences. :D

"If you are seeking optimum performance it is not wise to over or under emphasize any component."

+1 with Doug here. I'm of the "everything affects everything" school.
