Marantz AV7706 11.2Ch 8K Ultra HD AV Surround Pre-Amplifier with HEOS®

OK, the 7706 is a processor, not a receiver.

BTW, I have a Carver AV 505 powering my height channels that aren’t active, great amp! Same pedigree as the A series you have using trickle down tech from the Lighstar.

For a receiver I recommend the Marantz AV50 (with the Audyssey or Dirac upgrade), the Onkyo RZ50 with Dirac or the Sony 5000ES.

You can’t go wrong with any of them, I think the online dealer Audio Advice carries all 3 lines and you can call for details. Onkyo and Klipsch have the same corporate owner so that might be a plus.

Thanks kota.

Those were not even on my radar..

I’ll check them out.

Denon AVR-X4800H?

The Sony is interesting with the 5 year warranty and support for wireless rear speakers.  But the, 2,  subs are not individually controllable as on denon, onkyo, marantz, though the onkyo has only 2 sub outs.. and all of these have but a 3 year warranty.  But will I ever use 4 subs.. shrug, for HT I only have 1 now. Though it does get a bit boomy.. though less so since I started with room treatment panels.

But the onkyo does have the klipsch integration for, most, of the speakers I have on the HT system…

bleh.. choices.. sometimes too many..  I need to create a spreadsheet to keep em all straight..oh well, at least I have time since the current onkyo still works.

Another one to throw into the mix is the Arcam AV40/41. I've had mine for two years and have nothing but good things to say about it. It beat out Marantz and Denon no pure sound quality (HT and music) when I was in the market and auditioned.

I've used it for HT purely and have a separate 2-channel system.
