Listened to the latest Ozric Tentacles "Technicians Of The Sacred" (2xCD), in DD ProL II Music, and it was very immersive, some discrete activity, a lot of the double tracking/echo came out of the rears, way better than the plain stereo! I started wondering if it was deliberately done. Seating position as recommended by Sony/Philips for SACD, so closer to the rear speakers, though with the rears toed-in probably to 130-140 degrees.
