No experience with the Boston Acoustic VRM90, but I owned the Denon 2801 and found that when it came to music reproduction, that it was a difficult receiver to match both CD players and speakers to. I had the best success with Acoustic Research (I also had tried EPOS 11; B&W 302; Optimus Pro LX 5). I used the AR 302, but I have also heard the AR 11C & 9C (both tower speakers)in a HT set-up and they were excellent with music. If interested, take a look at www.accessories4less.com, where they are steeply discounted ($400 & $600 pere pair respectively).
Good luck.
