I'm looking to upgrade my speakers from 8-year old Bose 301's to go with my NAD T762. Up until yesterday I was dead set on going with another, albeit better, bookshelf model for my L/R mains. I previously tried Axiom and now have a pair of NHT M5's that I think I like, but I've started doubting them. And as a consequence, I'm doubting that I can find a bookshelf that I'll be happy with. I've auditioned a few other bookshelf models over the last few months but have started to realize that I might be better with towers. I prefer to listen to music in 2-channel stereo (no sub) but have yet to hear or read about a bookshelf that does this really well. But then I also wonder if I'm being too picky/anal about it. I've moved the M5s to positions at the sides of my entertainment center (previously on top). They sound a little better, but they don't jump out at me as "keepers". If I have to go with stands to support bookshelves, I might as well invest in a decent tower speaker; Paradigm and PSB models I've read up on have relatively small footprints and probably wouldn't be so bad in my room. Another thing I noticed is that the receiver got really hot after watching Matrix Revolutions (2+ hours, 2-channels). The NAD should be able to handle the power demands of the 6-ohm M5s, but then again I'd be adding a 3rd M5 for a center and a necessary sub, not to mention the surrounds. The cabinet housing the NAD is well ventilated, but I was surprised at how hot the unit got after the DVD finished. The funny thing is, the first time I heard an NAD receiver, it was in a dealer where a customer was auditioning PSB and Paradigm towers. Before purchasing, I auditioned the NAD at the same dealer using the same speakers! And now I'm thinking of going back and auditioning those very speakers for my HT. I realize I may have answered my own questions with this stream-of-thought rant, but any thoughts/opinions are appreciated.
