new at this...which amp?


I have B&W htm1 center, cdn nt9 front, cdm nt7 rear with Adcom 7500 150 by 5 amp and Adcom pre amp. The mids and highs are harsh beyond half volume. Speaker cables are the good stuff, but interconnects are Radio Shack's best sheilded cable. I have been told here that while interconnects could be the problem it is more likely lack of power. Would Adcom 7805 300 by 5 be a reasonable choice for a new amp? Is there a better choice for around 2500.00? If the 7805 is not enough I am considering bi amp with the 7500 and 7805 as the final solution. If so, would the more powerful amp go on the bottom end? Your comments are greatly appreciated.

Me too...sort of. My suggestion is the same as many here have offered. Check the cables you are using. B&W speakers- regardless of what you think of them, are really revealing of the contributions components bring to a system. I Love this about them, even if it has meant a little more experimentation. I am not familar with the 9nts models, but I have 1nts. My own experience has been that they can sound harsh when under- powered or when at the receiving end of a bright source or interconnects or cables. They sound bright where brightness is evident! In my system they do not sound the least bit bright or edgy, and they have given a much better account of recordings than I got from the their 600 series sibling... and this from a system I would consider less capable than yours.Really, I wonder if just changing out the Denon source for anything else for any amount of time wouldnt serve to show you the difference a little change could make?
