Anyhow, getting a quote on the SCS 8 if that is to unreasonable I will just buy a couple of sets of the 308 and replace the 802D and HTM1D in LCR duty for a night or two to see how much they will stand… If they are not up to the challenge the kids can have them as a stereo set in their room. Will see.
Thanks for all responses and for the tip on potential price hike on the processor, not sure if US hikes will influence us here on the other side of the atlantic, will check with our local dealer.

The Trinnov processor does not have Auro 3D, the SDP-75 does. For a while longer the SDP-75 is several thousand dollars less expensive than the Trinnov.
Synthesis certification requires use of Synthesis products. You can get calibration done but not certified. With M2's you want the SDP-75, Trinnov does not have the anechoic data, the SDP-75 does. As far as I know, the only speakers it has anechoic data for are the M2, LSR 7 series and the SCL (in wall) series. They don't put in data for all the speakers folks "might" use.
Then I have had a couple of hour with the 308 MkII in LCR service. Little hiss but not audible beyond 0.5 m in our room, so that is an non-issue.
Started off listening to music in 2 channel with sub (90hz crossover) and it was shocking good for the price…. Impressive and stable soundstage and the surround effects in the Qsound on Madonna’s Vouge was markedly better than the 802Ds…. Did not sound strained even on quite high level (-7 on the processor) on two channel with the sub connected. Cutting the sub however they shoved strain in the bass area at higher level and it sounded like some sort protection turned on at one time.
I did not get to look at much film bit I got to listen through the Atmos bathhouse scene on john wick at level -15 and it was sounding very good, tried it one more time at -10 and the dynamic of the gunshots was IMPRESSIVE. Was afraid of killing the tweeters but no protection seams to kick in… The quality of the background soundtrack “THINK by KALEIDA” was also shockingly good. Even if it is not possible to A/B them with the 802Ds they made me not miss the B&Ws at least on this short listening session.
Will listen more tomorrow but so far count me impressed…
The Atmos soundtracks I have heard in our setup so far I have not experienced this level of sound energy that was sent to the centre (and L&R) channel 308 on this clip sent to Surround or atmos channels. Based on this my thinking so far is that they will stand Surround and Atmos service quite well…
They were however a bit bigger than I had envisioned so they will dominate at least in Atmos positions… The light in front also needs to be “killed” If I will land on using them but that is of course a minor issue :-D
