I am not familiar with the disc you refer to but Rives Audio makes a good test CD.
Chesky Jazz Sampler & Audiophile Test Disc Vol.1. Not only does it have an outstanding left/right/center/and beyond track but it was truly an eye(ear) opener on the track where they would play a tambourine slap miked up close, than a few feet back, than a few feet further back. Made me realize how careful I had to be when reading reviews and opinions, unless one is familiar with the recording being used for evaluation, it's all a crapshoot.
Chesky Jazz Sampler & Audiophile Test Disc Vol.1I don't think that's it for I have the same disc. Just listened to the test part. There is no female vocal following the far right and left demo. Also when in far R or L he states his voice may be a bit disembodied for it is an extreme location. Great disc though. I was most impressed with the up and over. I also like the jazz sampler in the beginning. I would recommend this disc.
