A/V Receiver Recommendation for a newby.


Hi folks. I'll be the first to admit I'm not very knowledgeable when it comes to home theater systems.  I know the basics . I recently bought a  pair of Bowers and Wilkins 702 s2 speakers along with the htm 71 s2 center  channel. I have a pair of PSB GB1 book shelf for the rear speakers.  I currently have an Onkyo TX-NR676 a/v receiver.  I've been told by multiple people that this receiver isn't powerful enough to drive the B&W speakers and am looking to upgrade. I do have a limited budget after shelling out $6000 in speakers. I was wondering if anyone has experience with the Onkyo  TX NR 797 or Denon avr 2600h or recommendations My max budget is $1000.
Thanks in advance.

My 12 year old Onkyo HT receiver has better "SQ" than any movie theater I've ever been to. Alas, I've just learned that isn't good enough.
I would say ht is  about 70% of my usage and 2 channel music listening the other  30%. Thanks.
Buying a used Anthem MRX 520 (or similar) is likely your best bet.  Then look for a good 3 channel amp in the future to use for your front speakers.  The Anthem AVR receivers have analog pre-outs so that you can add an external amp anytime.
Thanks Aux. I did research the Anthem per your recommendation.  It does look good. However the  520 doesn't have Dolby Atmos or DTS X which I've switched most of my movies to 4k ultra with one of those two as the  sound format. I saw the next step up the 720 does but is around  $2500. I'm very naive about preamps to be honest.  Right now I'm bi-wiring and bi-amping the two towers. Was hoping maybe the Denon 4500h would be a vast improvement over what I have. Thanks so much.  I may wait a few months and save for the Anthem if you guys feel it's worth the $1,200 money difference. My wife wants me to get something that will last for  5 years or better.
