FWIW: I just got myself a QNAP 469L, with 2x3TB in RAID1. Following M's instructions, creating the Sooloos share and installing the QPKG plugin was pretty straightforward. I disabled the storage on the MC200 -- all shiny and new 3TB's are proudly showing as 'Non-Sooloos storage'.

Imports are fast (as in: no noticable difference with the MC200 only) and music plays instantly (as it should).

Sounds better too. wink
