What about the Barclay James Harvest, Once Again SQ CD from the UK? It even has the SQ logo on the front cover and a bonus Brazil only quad song on it. I have listened to it through my Tate and the Phase Matrix position on my QRX-6500 and it is indeed an SQ quad CD. The first song is a bit distorted, but the rest are pretty decent. A bit Floyd-like I think. You will see them come up on eBay once in a while; usually under ten bucks. Cheers, Mike.
