Sorry - forgot to add, which might be relevant, that in my opinion the SQ of the analogue output of the MC200 into my second system sounds substantially better than the SB3.

With regard to metadata, I've bodged it for myself but the Erland structure sounds great.

@Dollar2 I didn't want to pull ethernet cable around my house so am using 200Mb/s homeplugs with my ID40 plugged into one and so far so good - no dropouts or freezes (both MC200 and TwinStore are hard wired with Cat6 into my switch which is directly connected to my router).

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
