what amp under a grand?


I have vienna acoustic mozart grand marantz sr5005 avr,marantz 8001 sacd,vieanna theatro center,b&w 600s3 for rears,current amp adcom 555mk2.looked at used parasound hca 2003 thx, rotel rb 993, and and an adcom 5802.im fine with the performance the marantz gives me for ht but for two channel sound is muddy. i think its the amp? any advice on a used amp that would bring out the detail of the mozarts?

Agree with Mtrot, as I don't think the amp is the problem as long as it is functioning properly. Could be a room interaction issue. What is the distance between the speakers and back wall, also between speakers and side walls?
cd player analog ran with audioquest king cobra,speakers ran with audioquest mont blanc,amp to avr with audioquest jaguar. distance between speakers is 8ft,30 inch from side and rear walls.
Well, it seems like those are very good cables, so maybe it is some sort of room interaction. I'm not much of a guru on that topic, but I have heard that square-ish rooms are not good. What are the room dimensions? It could be that a bunch of reflections in the mid frequencies are producing the muddy sound.
yeah i think youre right about room interaction,didnt really think about that.the adcom 555mk2 and 5802 was adcoms best amps in my opinion.could try other things like audioquest pwr cables? granite plinth under viennas.

What is the floor? wood or carpet?

Are you using spikes under the speaker or is the speaker cabinet sitting directly on the floor?
