Looks tidy. I hope it works out for you. I tried a couple of 8000Ms with an 8000Q a few months back but they sounded way too harsh and toppy in my room which seems to suck out bass. Do your 8000Ms hum at all? Mine did. Also, one of the 8000Ms died after only 2 days for no apparent reason. I managed to send the whole lot back to Superfi and traded them for the Quad 99 pre + 909 power which was fortunate for me. At least with the Quad pre I can compensate for the bass loss by cranking it up a bit.
By the way, what's the issue with cables touching the wall?
