Each test disc offers something different. Some discs contain
useless filler which advertises a product or shows a unique
capability, but really doesn't help you test or improve your
system.
Many use the Hi-Fi News & Record Review test discs. So far,
these have received only positive comments.
Chesky produces 2 test discs. The first, "Chesky Jazz Sampler
Volume I" contains some excellent imaging test signals (called
LEDR), some well-recorded acoustic jazz, and other test signals.
The second, "Chesky Jazz Sampler Volume II" has similar music &
different tests.
Stereophile produces three test discs.
Denon also produces two test discs. The first, "Digital Audio
Check" is more useful for home use. The second, "Audio
Technical" is more for repair shops and test-disc addicts.
