If their previous reply is true: >>Classe's position is that these issues are inherent and not resolvable,<< then it makes no sense to try different hardware.
OTOH, if you want to try a different HDMI board, maybe rolling back to the original 1.3 version is worth a try. I still have the perfectly good HDMI 1.3 board here that I removed when doing the 1.4 upgrade. You are welcome to it. Of course it takes some effort to swap the boards and then upload the correct 2.0.6 firmware. I imagine Classe has a load of those sitting around, too, and might send them free of charge. I sense you are beyond that point in your mind. Understandable.
Short of changing hardware, if what RoubaixPro suggests is true, that the problem is related with latest firmware, you could try rolling back the firmware to 3.0.1 or even 2.9.9. I have these on hand if you want to try them.
Lastly, as I have the same hardware as you, I would be happy to install your settings backup file to see if that tells us anything. It's a long shot as we have different equipment attached. But it's free.
As for me I have added 4 ceiling speakers for Atmos so my affair with the SSP-800 is also winding down.
I'm going to ebay them and replace the main room with a Datasat RS20i and the secondary system with an LS10. I''m also going to replace the stacks of Classe Delta amps-which also have issues of inexplicably going into to protection-for Datasat amps.
Be advised the RS20i has an audible cooling fan, just in case the unit would sit within earshot. If not, then no problem. Make sure to hire someone well qualified to do the Dirac tuning.
As for the amps, unless you need the cooling fan and input switching facilities of the Datasat, you can save some money by buying the AT6007
amp (same performance) or even the AT2007
from the OEM maker of the Datasat, ATI. In fact the AT2007 is also sold as the Outlaw 7700
for much less. All solid performers.
