Home Theater Receiver recommendations for B&W 803S?


Hi!  I'm on the hunt for a new receiver, since I recently upgraded my main speakers, and I'd like to have one that also passes 4K signal.  

My current setup:

Denon AVR-4308CI
Left & Right: B&W 803S
Center: B&W HTM2
Surrounds B&W 301
Sub: Energy 8"

I recently upgraded to the 803S's on the left/right; replacing my original Nautilus 805's.  Now I need to upgrade the rest of the system!

I think the first step is the receiver, especially since I'd like to be able to pass 4K to my projector.   Then will likely upgrade the sub (Am considering the Monoprice Monolith, 10" or 12"...). And I'm also on the hunt for a HTM3S, to better match the 803S's. 

I'd love to know what Receiver recommendations folks have that will pair nicely with these speakers.  Ideally under ~$2K  - and I really don't care much about other bells & whistles (multi zone, bluetooth, wifi, whatever). I'd rather the money go into the best possible D/A, amplifiers, etc... and leave other tech gadgetry to other boxes.

Appreciate any/all input! Thanks!  :)

Oh one more option that caphill likes to recommend is the Classe Sigma SSP processor.  It supports 4K, however only supports HDCP 2.2 through one input (HDMI input 4).  It is also a very nice processor, but as good as it is, it does not have discrete analog stages like the Marantz.  The Classe is quite a bit smaller, so if size is an issue, than Marantz may not be an option.  The Marantz is definitely a beast.  The Classe Sigma SSP is in the same $2500 price range.  There's actually one for sale from TMR Audio for $2408.

In a comparison, Marantz AV8802a with fuse upgrade VS Classe Sigma SSP, I honestly do not know which one would win.  Personally, I would actually go with the Marantz and work with fuse/power cord upgrades because of the fully discrete analog stages.  In all my R&D and testing with circuits, as good as monolothic op amps can be, they never reached the sound quality of fully discrete analog stages.  My own personal opinion, of course.

The current model Classe Sigma SSP Mk2 retails for $6k new and even used it will be in around $4k ish since it supports the latest formats and is current model as far as I know. I’m worried that the Sigma SSP that you saw for sale for $2408 was possibly the original first gen Sigma SSP that does not support 4K and all other current formats, that’s why it’s being offered for sale for $2408 because it’s been replaced by the Sigma SSP Mk2. The original retail price of the Sigma SSP (first gen) was $5k.

The Classe Sigma SSP is optimized for stereo. If the OP focus more on home theater I would go with the Marantz AV8802 as it’s also easier to calibrate for surrounds using its Audyssey auto room correction. The Classe lacks auto room correction but provides manual PEQ instead which requires proper tools and equipments and knowledge on how to implement it. The Marantz AV8802 is much easier to calibrate using its built-in Audyssey even though I’m not a fan of Audyssey at all.

For stereo music, we did compare the Classe Sigma SSP with the Marantz AV8802 and both processors were paired with Classe Delta CAM-300 monoblock amps (class AB) on B&W 802 D3 speakers before at my friend’s shop and the Sigma SSP sounded better for stereo music playbacks more musical and better sound overall. We used the Sigma SSP’s USB input to stream music and we did the same with the Marantz AV8802. The Classe Sigma SSP also has better DAC configuration/implementation at least for the front LR channels and has superb USB input implementation in its signal path, which is copied and pasted from Classe CP 800 stereo preamp/DAC. 

But for surround sound movies (home theater) both of them performed great but I would recommend the Marantz AV8802 for the OP if his primary focus is home theater and it’s easier to properly calibrate using its Audyssey auto room correction. The manual PEQ on the Classe is much more difficult to properly calibrate and becomes a deal breaker for some people.

Welcome awilder!  Set your budget and do your homework.  Make a list of must have features, then narrow it down to price vs performance.  If you can listen to a couple of brands through your speakers, then do so with familiar material.  Power is always important to avoid clipping or damage.  
B&w often recommends Rotel and the new integrated is a killer. I’d call b&w u.s. and ask.
