Upgrade from Classe SSP 800 processor

@soix

Thanks. I will have my Oppo 205 modded by Ric Schultz at EVS once I get a new processor. I finally just completed renovation works with my dedicated theater room in order to accommodate more channels/speakers eg overhead speakers for Atmos setup as well as surround speakers, etc. At the moment I’m using the B&W 804 D3 & 805 D3 for surrounds and will be trading them in for those B&W in-wall custom theater speakers (the matching ones for the B&W 800 D3 speaker system) for surround duties. For main front L/R speakers I have the big B&W 800 D3, and for a center channel speaker I have the matching B&W HTML1 D3. They are all driven by all big Classe Delta series class AB amps. See full descriptions of my HT setup in my original post above.

I just ordered a Lyngdorf MP-50 AV pre pro to replace my beloved Classe SSP 800. I’m going to sell my SSP 800 to my cousin. He’s currently using the Marantz AV8802 processor and now he’s looking for a processor that can perform really well in stereo for music playbacks and can function as a high end stereo preamp as well.
His AV8802 performs well for HT but its stereo performance is somewhat lacking in comparison to the Classe SSP 800. And he doesn’t care about the new formats such as Dolby Atmos, DTS-X, Auro 3D, etc

I will be looking for additional power amps to power additional speakers such as overhead speakers for Atmos setup, etc. Right now I only have 7.2 setup.
I will be going for 7.2.6 setup with the new Lyngdorf MP-50.
I am also looking to purchase B&W (matching for my B&W 800 D3 speaker system) overhead speakers for Atmos setup. I’m also going to trade in my B&W 804 D3 & 805 D3 speakers that I’m currently using for surrounds for those matching B&W in-wall custom theater speakers, the matching ones for my B&W 800 D3 speaker system.
As for additional amps to power the overhead Atmos speakers I might be getting some compact class D amp(s). Am thinking the Classe Sigma Amp2 stereo amp (class D) and the Classe Sigma Amp5 five-channel amp (class D) for those duties. I was initially thinking to get the Parasound Halo A21 & A51 amps but those are huge and run somewhat hot I’ve heard. So the compact Classe Sigma series class D amps would make more sense to power overhead Atmos speakers.
I am using all those big Classe Delta series class AB amps for my front LCR and surround speakers. See full descriptions of my HT setup in my original post above.

What do you guys think of those Classe Sigma series class D amps to power the overhead Atmos speakers?

Just an update on my end...    I ended up buying a new Lyngdorf MP-50 as well and just got it installed and fine tuned yesterday.   Simply incredible is all I can say.   I absolutely loved my Classe(until I had all of the Video drop outs), but can say with the Room Correction programmed and engaged that the MP-50 has taken movies to a whole new level.   Very impressed.

I'm working with my dealer to have Classe SSP-800 looked at.   If it is not too expensive to get it fixed, I will probably do that and list it here on audiogon.

Caphill - I've never listened to the Classe Sigma series class D amps, but I would think it would work great for Atmos speakers--small and compact with a lot of power.   If I ever decide to get the top front and top back speakers for Atmos I will probably do the same.   Right now I am running a 7.2 system.

Yes, Room Perfect implementation in the Lyngdorf MP-50 is said to be excellent. 
What power amp(s) are you using? Are you using all Classe Delta series amps?
Are you planning to go Atmos setup eg 7.1.6 or 7.1.4? 

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.
