Well yes sort of , yes.
Interesting that it says Quadraphonic on the vinyl album cover , but I wonder why it also states gives 7 DISCRETE channels when decoded , with DPL 1 , DPL2 , RM , or QS ?
Two other quad matrix silver discs that come to mind are almost recently released by Dutton Vocalion and A. F .
Herbie Hancock - Sextant , SACD 4.0 w/ an SQ stereo layer , and Audio Fidelity's Santana Lotus 2ch SACD SQ .
And in DV's case there is the likelihood that we will see more like that Hancock disc. At least I hope so.
