I spent the last month comparing the SQ Vinyl Beta to the Original Surround Master and I have to say you guys have hit another home run. As claimed, the Vinyl version improves the 4 corner crosstalk between front & rear speakers. For me, where I sit in the rear end of the listening room the dynamics & separation between the left & right front speakers are easier to pick up - even when the back speakers are active. This improves the listening experience for several albums- Loggins & Messina, Chicago, Sly & the Family Stone & Poco come to mind. Sometimes what I thought were center front vocals were really L-R, C-L, or C-R exchanges. Nice to be able to pick up these subtleties! I'm curious to hear how close the Loggins & Messina album will be when I get my hands on the AF SACD next month! Classical ambience mixes sound the same as the original unit: excellent. So all in all the SQ decoding is improved & remains smooth. No artifacts at all. Other than that the unit is exactly the same as the Original with the same excellent QS decoding. Good job guys!
