Time for some update [ @Reverb @JonFo - maybe time to move my thread to "adults" part of the forum, but I am also happy to be still considered newbie]

1) Acoustics - somehow I believe I am where I need to be - thanks to 2 major changes - I have darkened the windows with film, I could remove 1 layer of curtains and I have moved from absorber panels in the first reflection points [front/side/rear wall] to combined diffusion/absorption cylindrical panels [approx 1/3 of absorption of normal panel + quite broad diffusion, frequency wise]. Added couple of light diffusion plates on corner bass traps.

REW measurements show now much more even reverb time across critical frequencies [before I had a "hole" between 500-1000Hz, where RT60 was by 0.05s shorter, now all good and also L-R symmetry. Couple of pictures. Optimized primarily for Stereo.

2) Hardware - moved to 9.5.6, adding Motion 15 as FW and 2x Motion 4 + Dynamo 1100 - all good. now front looks like this.

3) Live with TRINNOV - just awesome - once you learn some of the tricks, learn how to measure properly, it takes it all to completely different level. On top you have their excellent customer support, where they took my measurements/presets and adjusted couple of settings in "do not touch, unless you really know what your doing" section, this brought the overall Stereo and MCH sound another notch higher. E.g. using crossover HPF/LPF and slopes asymmetrically for some speakers, they got all the Bass Management crossover regions in-phase and this is really audible. E.g now my Dynamo 800 is used as woofer, dedicated just to C channel without any LFE duty and this already make a lot of difference in L-C-R sound coherency.

On top - with TRINNOV being fine up to 6V, I could lower the gain on power amps to 20dB and this brings another small piece of calmness and transparency.

I had regional distributor of ML delivering those speakers to my place, so we spent 2 hours listening to both music and some movie material - and his statement was - "it does not get much better". Stereo is now really shining - sweet, detailed, spacious, holographic with no hint of any digital harshness [this is what speakers being in-phase in every frequency brings you] + 5 subs crossed at 60Hz and optimized as one sub. Re-discovered my love for music again, listening to all the old stuff again and again.

4) What next - I think I owe it to the rest of the chain - I have placed order yesterday - Height speakers - I will go from Motion 4i's to Motion 15's. 4's - nice as they are, you just can not overcome laws of physics - 4in woofer will not have SPL and FR that you need for higher end application [I need to cross them over at 110Hz, which is borderline] and Surrounds/Front Wides I will move to Motion 35's [upgrading from Motion 8& Motion 15]

And now comes the real conundrum - what to do with spare channels ;-). Makes no sense to go above 9 bed plane speakers, so all good here. My options are - I take back Motion 50 C and use it as Center Height creating 9.x.7 or add some extra sub/subs or go for 9.x.8 and add Atmos Front Tops.
Life was much easier with 5.1.

Good stuff mate! Well done on the room and specifically designed for HT and 2ch music.
I always tend to forget how well designed those Expression 13A's are, give them plenty of space and matching quality in gear, and they will perform supremely well!

The Summit-X were really good, until the new Masterpiece line came out, it was pretty much a paradigm shift, both in terms of stat performance and LF detail. I found that the bass drivers aligned in this proprietary B-F way provides extended bass lines, with greater clarity and layering. Not just a thump. Also makes music far more believable.

Looks like there's been a lot of effort put into this project and dedicated room, well worth the effort. Also agree on the Artnovion acoustic panels, they're outstanding! Pricey though but they do a marvellous job! I think they're made in Prague...

Cheers, and keep those fine tunes playing!

Does your Trinnov have HDMI 2.1 yet? If not, what is the procedure in Europe to get it installed at a later date?

No, I have 2.0 still [bought it just before the latest price hike in June 22]. I have upgraded DAC board and it was pretty straight forward, while drinking some coffee at the dealership [but it is 30 min drive for me].

I assume HDMI and extension board will be the same process. No idea about current availability though.

So, finalized my setup this weekend - final 9.6.7 in 32 sqm, will add some photos tomorrow. Need to say it sounds really amazing, compered to heights based on Motion 4i. I think I am done for now. I jut need to clean up this endless mess, that are my cables.

I have created one Sub Array in Front - see picture - and now it really has a oomph to the movies, but also headroom and punch for music.
800x is used as dedicated sub for C, and only Sub array is on LFE duty. then I have L and R Surround/Height areas with one dedicated sub each

Side to side comparison of Motion 4i, 15i and 35XTi, 35's are aready quite big pieces of furniture

And now front side with 4 subs - 1600x are both at -9dB gain , 1100x at -6dB gain, so that I get to reference calibration level of 80dB, combined with room gain I end at -3dB at 16Hz.
