Upgrade from Classe SSP 800 processor

I have an older Krell Theater Amplifier Standard 5 channel for the surrounds and use a Gryphon Diablo 300 in Home Theater Bypass for the L and R channels(for two channel music listening I use just the Diablo).

I'm considering going to a 7.2.4 Atmos setup.  My problem is that I am really maxed out on my AV shelving at the moment so I would need to go with something small like the Classe Sigma to wedge the extra 4 channels in to the system. 

Yes, just get a compact class D five-channel amp such as the Classe Sigma Amp5. I have heard the Classe Sigma Amp5 & Amp2 at a dealer right when they first came out in 2015 so it's been a while ago, but yesterday I had a chance to hear it again at a local dealer and wow! they are fantastic especially for HT (surround sound movies). Its sound is highly resolved, very detailed, smooth, fast, very dynamic with plenty of slams, very clean with unlimited reserves of power and are able to drive just about any difficult loads. They aren’t my kind of amp for listening to music but for surrounds (HT) the Classe Sigma Amp5 are perfect and found nothing that can be faulted.

The Classe Delta series class AB amps are indeed quite a bit better amps than their Sigma series amps especially for music and are in different leagues but the Delta series class AB amps, like the ones I have in my dedicated HT room, are huge massive and very heavy and lot more expensive than the Sigma series amps.
But those Classe Delta series gears were discontinued last year and if you could find a used one they will be discounted.

So the Classe Sigma Amp5 & Amp2 would make more sense to power those overhead speakers for Atmos setup they are small compact and pretty light weight due to class D design.

How’s your Lyngdorf MP 50 so far?
I’m still in the process of breaking it in. I’ve had Room Perfect properly set up and calibrated and all and got 4 overhead height ceiling speakers for Atmos setup, so my current setup is now 7.2.4. Have added additional power amps to power those overhead ceiling speakers for Atmos setup. I purchased two Classe Sigma Amp2 stereo power amps for that duty since they are compact. Figured it’s only for powering those overhead ceiling speakers for Atmos setup anyway. But all my other amps are Classe AB from Classe Delta series paired with all B&W 800 series D3 speaker system.

I really like it and the room calibration was very easy and works really well(99% calibrated).  
A couple of comments though...

First, I find that the Classe is more configurable overall than the MP-50.    A lot more different settings and configuration options in the menus.   Not that I needed all of them, but they were there if I did.

Second, initially I found the detail and soundfield of the mp-50 to be crazy good, but after a while noticed that some of the body that the classe had was not there; plus was a bit fatiguing.   Wasn’t sure if it was the result of the room correction or just the house sound of the lyngdorf.  I changed the powercord out to a Audioquest Hurricane that I had been using on my renderer and all of a sudden it was there again.   The body and fullness I had before plus the hi def soundfield.

Overall I am very happy with it as a home theater processor.    

BTW- I did compare the two channel capabilities of the Lyngdorf and internal Dac to my Gryphon Diablo 300 and Chord Dave DAC to see what would happen.   The gryphon with the chord was a lot better, but I would have been amazed if it had not been.

How about you?   Thoughts?

I’m still running my Lyngdorf MP-50 in in order to get it properly and fully broken in. I still haven’t really sit down to make thorough observation yet from a sonic standpoint until it’s fully broken in. I will report back once it’s fully broken in. But so far I’ve been pretty happy with its surround performance with Room Perfect properly calibrated. I’m sure it will only get better over time.
I’ve been using the Shunyata Sigma power cord with my AV processor.
Yes, I agree with you regarding the settings and configurations of the Classe SSP 800 which I found better than the Lyngdorf MP-50. And my gut tells me that basic sound quality alone for two channels without any room correction engaged I think the SSP 800 might be a bit better but things change when the RP is engaged and properly calibrated for surround sound performance (home theater).

It isn’t a fair comparison when you compare the two channel capabilities of the Lyngdorf MP-50 with its internal DAC of course (since the MP-50 does not have analog audio inputs) to that of your Chord Dave DAC and Gryphon Diablo 300 as they are totally different animals and at different price points too. Your Chord Dave DAC alone retails for the same price as the Lyngdorf MP-50 processor which is at $10k. Of course the Chord Dave DAC and the Gryphon Diablo 300 will crush the Lyngdorf MP-50 by large margin. Btw, I’ve heard the Chord Dave DAC in all Naim setup paired with some higher end PMC speakers and they sounded fabulous.

I haven’t got around to compare my new Lyngdorf MP-50 two-channel capability either its internal DAC to that of my dedicated two channel setup that I have in a separate dedicated stereo listening room. Cause my Lyngdorf MP-50 is used strictly for home theater (surrounds) and I have nothing to compare it with in my dedicated home theater room as I don’t have a stereo preamp and a standalone stereo DAC in my home theater room to begin with.
And my dedicated stereo gears that I have in a separate two channel listening room are of high bars. My digital front end consists of the following : DCS Vivaldi full four stacks (Vivaldi master clock, Vivaldi upsampler, Vivaldi DAC, Vivaldi CD/SACD transport). And I am using the Naim Statement NAC S1 linestage analog stereo preamp and the Naim Statement NAP S1 monoblock power amps. These are all cost-no-object design gears and of course and I have no doubt that these will crush my Lyngdorf MP-50 two channel performance with its internal DAC. Not fair comparison to begin with. They are totally different animals and aren't in the same league at all. The Lyngdorf MP-50 is a great performing AV surround processor equipped with spectacular RP (Room Perfect) room correction and it does great job for surround (home theater) duties. That’s what the MP-50 is supposed to do and it does it so well.
