There is an audio company called Chesky (
www.Chesky.com ). Through Amazon, I received - The
Ultimate DVD SURROUND Sampler & 5.1 Set-up Disc. Chesky does some pretty great 5.1 (and 6.0) recordings.
Unfortunately of the 2 disks I was supposed to get, I only got the jazz / classical sampler. While I like Jazz & classical, I really was looking forward to their test DVD-A to really check out the Lexicon performance from a technical perspective. The booklet that comes with the disk set is REALLY informative about 5.1/6.0, all about DVD-A and more.
The Test disk has standard things like channel ID-ing for all channels; rattle test; several various tests of the bass and sub; comparison of stereo & 5.1; AND..... get this.... a 5.1 recording of a NYC subwayride!!
I'll give another post when I get the Test disk and run it. I have the 17 speaker Lexicon so if the player will handle it, I'll also try the 6.0
