What AV amplifier for 4 x b&W + centre

@tcooper656 — what preamp were they using for a preamp when you bought your amp?  If Classe, maybe it would make sense to consider a Classe prepro.  There are several SSP800s available here now around $2500 originally priced around $9000.  I don’t think it does the latest things like ATMOS but sounds like that might not be important to you.  Obviously there should be good synergy between this and your new amp.

like your post. I was so much impressed with the sound and the amp I did not even notice the ore amp it was used in the set up.   
I am using my Arcam 850 s a processor and very happy with the quality for both the TV and music 

I was told Classe due to launch the new processor   Is it true ? 
My system is only 5.1 so maybe I do not need the latest technology    It has to support 4K though 

thank you all for helping me to get where I am at now !!!!

Tom, your on to it with your suggestion of separate multi-ch power amp to bi-amp L&R speakers and use your Arcam for other speakers.
For now, if you Arcam is a 7.2 avr and allows bi-amping L&R speakers you'll notice a step up in sound w/o investing any money for now. I use a Yamaha 140 wpc 7.2 amp and I'm able to allocate 2 rear surround channels to the front L&R for bi-amping and noticed improved sound from front speakers.

Oops! I just read all the posts instead of skipping half of them, so disregard my previous post. I see you made a really nice choice. Classe/ B&W is a classic combination. Hopefully my previous post will be of use to someone sometime.
