Amp recommendation please

I have a pair of aperion verus grand bookshelf speakers as mains and a marantz 1403 receiver and am looking to run an external amp from the main preouts. I would like something around 200-250ish dollars used and have seen a lot of amps that look decent. Any thoughts on brands? I have been looking at nad, rotel, adcom, parasound, etc… I do use them for home theater but would love something for 2 channel music (jazz, acousti, some rock and electronic.) Also I've read that different amps affect soundstage? If so my speakers are closer together than I would like just because of room layout so anything that could help soundstage would be good. Thanks, Keith

AMPLIFIER

An amplifier has little affect on soundstage.

Most of it is the speakers themselves, and their placement.

Small changes in placement can make a very large difference, so experiment.

My past experience is that you are not going to get what you want in any cheap amplifier from Parasound or Adcom.

You might get lucky and find a NAD or Rotel that would be decent. What you need, to get much inprovement, is an amplifier with a very low output impedance, which in practice means a power output of 100 watts per channel or more at 4 ohms.

That is a pretty low price range.

What is the center-to-center distance of your speakers, and how far is your head from the speakers when listening.

One thing that can make a TON of difference in imaging is the amount of toe-in. I had my speakers toed in so they were pointing at me, and the imaging was not very good. The imaging is MUCH MUCH better with mine when they are not toed in at all.
