Found this link to a scanned magazine article in another forum:

This appears to be a very old article. You are welcome to draw your own
conclusions. One thing I found interesting is that the comments on the
$12K amp are very similar to what some audiophiles say about SACD
(compared to CD's in particular). The overall ratio of right answers
also is amazing: 388/772. 386/772 is *exactly* 50%.
