I get a few ID41 dropouts - maybe one a month or one every two months. Enough to be a mild irritation but no worse. Ethernet over power. Solved by restarting the ID41 by holding down the repeat button on the 808 when in standby.

MC200, Twinstore, 808v6/ID41 -> DSP8000SE (+ SB Touch, Sony BDP-3300, SKYHD, legacy cassette player)
2nd system: MC200 analogue out, Linn LP12, SB3 -> Quad 34 -> M60 rosewood
