Speaker recommendation for Home Theater

The Classe CT SSP/SSP 800 is spectacular. I owned the SSP 800, which is basically the same as the CT SSP, for almost 8 years until recently. Now I have the Lyngdorf MP-50 cause I want Dolby Atmos, DTS-X & Auro 3D and the Classe SSP 800 does not support these formats.
That's the main reason I sold the Classe SSP 800 and got the new Lyngdorf MP-50. 

I'm back.  Long Thanksgiving holiday.  Whew...  

I've decided to go with the Dynaudio Contour 60/25c combo for my mains and center channel – I liked 'em a lot!  Since our last discussion, I've started to re-balance my listening habits.  I really want to get back into 2-channel listening so this likely changes things a bit (sorry about that).  

Here is what I have on my short-list for completing the system: 
1. Dynaudio built-in speakers for 7.1 setup (side and rear surround speakers)
2. Marantz (used) AV8xxx pre/pro
3. Musical Fidelity M6si (or similar $2k ish integrated with HT bypass)
4. Multi-channel surround/center amp (Parasound? Emotiva? others?)

My thinking here... admitted primordial...  is to get a good 2 channel setup that can double as a decent home theater setup when the family enters the man-cave.  Given I've just pulled the trigger on a lot of speakers, I need to be frugal for the rest of the setup until I can recharge the play-fund (likely 12-18 months).  

Sorry for the curve ball but would value your continued advice.  

The Dynaudio Contours are really good, we just heard them at the NY audio show, and we were impressed.

Your idea on the Musical Fidelity M6 is a good one they are very powerful and clean, we would recommend a high quality surround sound receiver to power the center and any surrounds. 

The Anthem MRX 720 is fantastic for $2,500.00  if you are looking for a great sounding powerful receiver look for a used Cambridge CX 200.

Or move up to one of the higher end 2 channel integrated amplifiers like the Anthem STR which has a great built in dac, offers room correction and 250 watts on tap.

Another great integrated is the Coda CS IB a 400 $6k watt powerhouse no dac, with 5 watts pure class A amazing build and sound quality for a purist 2 channel integrated. 

If you are going back to 2 channel than you want to put the money into a really good 2 channel integrated and use a good quality surround sound receiver to power the rest.

Also if you like the sound of the Dynaudio's see if it  there is a Legacy dealer anywhere near you the Signature is a worthy competitor to the Dynaudio similar tonaltity big and warm, big soundstage very deep bass and it is only $7k a pair you might really like them.

Or instead of getting the Musical Fidelity M6Si integrated for your stereo needs and the Marantz AV8802/8805 HT processor for HT or surround sound movies, I would recommend the Classe Sigma SSP av preamp processor, which is optimized for stereo. If you don’t care about 4k pass through, HDR, Dolby Atmos, DTS-X & Auro-3D you should look for a used discontinued Classe Sigma SSP (early version that does not support the 4k HDR Dolby Atmos, etc) in used markets or some or few Classe dealers might still have it as a demo unit or left over stock. Today it can be had for around $2500 ish used. It originally retailed for $5k when purchased new. This model has been replaced by the Sigma SSP Mk2 version that supports 4k HDR Dolby Atmos etc and it retails for $6k new. They are basically the same preamp processor except the Mk2 version supports latest formats & codecs.

The Classe Sigma SSP’s stereo performance for stereo music playbacks are superb and its surround performance is also very good when set up properly but it lacks auto room correction and instead Classe provides a manual PEQ (Parametrix EQ) which requires proper tools and equipments and thorough knowledge on how to implement it correctly and properly for surrounds. Its stereo performance that stands out. The Sigma SSP sounded more like a high end stereo preamp than a HT processor. And the back panels of the Sigma SSP looks more like a stereo preamp/DAC processor than a HT processor. It has very limited and much fewer connections than all other HT processors. 

Classe originally designed the Sigma SSP as a stereo preamp processor but later on decided to add extra channels to make it as a surround processor. The front LR channels of the Sigma SSP is true differential design or fully balanced design internally all the way but the remaining channels are single ended design but very good single ended ones.
So for the front LR channels I suggest you use XLR balanced cables to connect to a power amp in order to fully optimize the stereo performance of the Sigma SSP. It is also DLNA equipped but its USB input sounded much better than its other digital inputs for streaming stereo music files.

And for the power amp you can get very good quality class AB amps to drive your speakers. I bet the Classe Sigma SSP, especially when using its USB DAC input for stereo digital music files, will outperform the Musical Fidelity M6Si preamp/DAC section.
