BGO CD set of these Chase albums arrived the other day.. got a chance to have the briefest of playarounds just now.
fwiw Track 1 of Pure Music in this BGO set does not resemble the SQ LP, in undecoded or decoded (by S.Master) form.
for one thing all the round the room panning is static in the centre, plus the mix just sounds different even in 2-ch.
also, while it doesn't sound too bad, there is atrocious tape drag in this track, which I don't recall hearing in the iTunes or Japanese Blu-Spec CD versions.
I'll try some more tracks out down the line but so far on the basis of the 1st trk alone, I don't think the BGO CD of Pure Music is the Quad unfortunately.
edit: in Trk 2, the guitar solo that pops up in rear left towards the end... is in front right on the CD when run thru the SQ decoder
(more horrendous - laughably bad tbh - tape drag at the very outro of this trk).
trk 3.. tape fluctuation throughout.. ugh.. I may snap this piece of shit in half in a minute.
trk 5: not in any doubt now, the CD is the Stereo, there's more reverb than in the SQ.. and there's short bursts of trumpet that do the 360 thing (FL, FR, RR..) in the SQ which are all just lumped into the CF on the CD when SQ decoded.
update: if you want to hear the Quad of Pure Music, I'd say don't waste your time on the BGO CD set. the CD does some fun things in PLII and different things when SQ decoded but its not the same as the (imho excellent) SQ LP.
