Not mentioning the engineer in the product description seems very strange. I mean, If the engineer has a good reputation in Surround Sound, citing him would be a good way to sell the product to this niche audience that cares about these things. The lack of more details leaves the consumer in the dark
Many times companies sell a product as new, but it's just an old thing that didn't sell very well in a limited format. I remember they recently sold Toto IV 5.1 as a brand new thing in a big box set, but it was actually an old Elliot Scheiner mix previously released on SACD only.
