I believe it was a discrete 3 channel recording. 5.1 recordings played reminded me of days of quadrophonic sound with band instruments playing separately from the front and from the rear. The best 5.1 recordings I have heard from dsd, Sacd discs, and bluray use the rear as ambient retrieval not discrete.
The Oscar Peterson and Nat King Cole files were, I believe, originally recorded with 3 mikes. If anything played out of the rear I could not hear it. The 3 channels sounded incredibly natural yet utterly clean and focused compared to the stereo versions which sounded pretty good until the 3 channel versions played.
Yes avrs can probably play this type of format, but II have yet to hear an avr sound anything like the Mytek demo at Axpona.
