2 channel amp suggestion


I've had mostly NAD gear for quite a while, starting with a 3020 years ago...a while back my OLD C270 amp started losing it in the right channel so I am using the Front speaker wires on my NAD 758 rather than Preamp outs and an amp while I research a replacement...my stereo music sources are an Oppo 103, Bluseound Node2 with HiRes Tidal account, and a Project Expression 3..but only with the Sumiko Oyster...(next upgrade?)...I have B&W CM9s with a Velodyne subwoofer filling the really low end in an oddly shaped living room...I see the 275BEE is the NAD replacement but the stores I have nearby have Atoll, Anthem and Rotel in that 2 "grandish" or less price range...any suggestions? Perhaps the Used market? Thanks...love this Forum...

It might be worthwhile to add the Parasound A21 to your list. I have the A21+ paired with my B&W CM9s and it sounds great! You should be able to find an original A21 under your price point on the used market or as a dealer demo if you look hard enough. 
Atoll stuff gets great reviews but might be a bit low on power for B&W CM9s. The Rotel stuff is usually a solid value. Anthem gear seems to have a history of reliability issues. 

If you need an integrated amp, the mosfet-powered Yamahas are hard to beat. Should be able to get an A-S1200 for ~$2K.

i recently bought an atoll - it is a nice unit, but i agree it is not that powerful, albeit pretty sweet, forward sounding for a low dollar unit

try a used hegel - they are very nice sounding solid state (not harsh in the least, very dimensional) and have very good control over dynamic driver speakers

I guess I haven't really thought about that...I've liked B&W speakers because to my ear they seem more flat...for example Klipsch or Focal sound too shrill to me...Focals are great in my car and truck though...I started with 600 series bookshelves and a subwoofer, then to 705s with the center channel and the 600s as rears...now its the CM9s with 600s as rears..same center.. but I don't really care too much about movies and surround etc...I was also looking to move up from the CM9s at some point and I listened to some Dynaudios that I liked but....the 2 grand is set aside right now for a good amplifier...first things first...with all the virus staying at home its got me wanting upgrades of course...
If you’re really thinking of upgrading speakers in the not-too-distant future, I’d look to narrow down what those might be as the amp you buy now may not be a good match for those.  That aside, as you seem to prefer a more neutral kind of sound, I’d recommend a used Hegel H160.  It’s a great all-around amp (you can read the reviews) and has enough power to get the most out of your CM9s, and there’s one available on US Audio Mart for $1900.  Hope this helps, and best of luck. 
Thanks so much for the responses...plenty of things to consider here, especially the used market...one question, comparing the specs on all these amps what are the most important? Obviously watts per channel only means so much and I always though current supply was most important? What specification gives me a sense of that capability? Thanks..
Im surprised you got any answers since you neglected to put a dollar limit in your post.
That said if it goes to $1600, there's a EVS 1200 (which I have, and LOVE) on Audio Asylum classifieds. RUN. It will be the backbone of your system from now on
I did mention a 2 thousand limit earlier, but it seems there are several options cheaper than that, yours being one of them...I am just checking them all out, that's why I was asking about how do I compare specifications listings for all these amplifiers beyond watts per channel and distortion...thanks for another tip...I am learning a lot about the various online sites also for other things like cables, maybe speakers etc..
