I have not tried that CD specifically, but Chesky recordings are usually quite nice.
A good audiophile friend introduced me to Chesky records a couple of years ago. They do a really great job on their recordings. From microphone placement and caputring gear, to the mastering and pressing of their CD's, they do stive for a higher level of quality than your mainstream CD's. That's sort of their purpose.
I have one of their CD's that has a few tracks of audio tests at the end. It's a simple 2-channel test suite that basically involves nothing more than one of their guys speaking to you as he walks around the stage describing where he is in relation to the microphone(s). Some other tracks involve simple percussion instruments. Utterly phenominal demonstrations of the depth and presence that can be achieved in 2-channel audio. From what they did there with 2 channels, I suspect the 5.1 stuff would be downright scary.
Of course, being a boutique brand, their selection is fairly limited. But if you like the kinds of music they sell, go for it!
