I was not aware of either the Tomita QS material nor the David Bedford UHJ album. I have Tomita's Snowflakes are Dancing original LP, which I have not listened to in years so I'll give it a listen on the G61s ambisonic (UHJ) decode and Trifield.

Sometimes re-releases of former UHJ material are not in UHJ. Cowboy Junkies' Trinity Sessions is one of these, it seems:( but I have the original (yay!).

Time to go hunting for any stuff I still don't have as well. Am about to do some .amb to .WAV B-format file conversions in Audacity. Beethoven's 4th is one of these.

G61RSL, G98-DH, G01, Quad 606, Quad 306 (x3), Quad-ESL63 (x 2 pairs, F&R), KEF LS50 (S), Quad 10L sub, Martin Logan Motif (CF) + miniDSP
