I already have SE DSPs and am planning to upgrade to 808v6 simply because I like to keep kit up to date (and Meridian is rare -unique - in enabling this), plus reports of improved SQ independent of MQA.

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
F80 (Rubino Micallizzato)
F80 (Rosso Corsa)
