What the heck is this?

I have a copy of the original Denon test record. Much of it needs to be used with calibrated instruments. The manual is intense. There are other records, Hi Fi News and Review for one, which are more user friendly. I got mine for a buck before Stereophile hyped it. As a matter of fact, 2 sets of records came with it. I would offer to send you a copy of the manual so that you can review it before purchasing, but it is too much work and would confuse most people. I will take a look at it when I get home and give you a more detailed report tomorrow.
