Just for you Paul, a scanned page from this booklet.

I'm sure a resourceful chap like you can find a copy if you look hard enough . It was published along with the August 1992 edition of HiFi Choice. You could even ask Choice or the author.
You are right though. You don't need to validate the credibility of Paul Miller. I'd like to see you put your criticisms of what he wrote to him though & to read his reply. Sadly I somehow don't think you will. Its easier to stay on here isn't it?
As someone who participated in the blind listening these tests involved it was quite apparent to me and the various other listeners present what differences were audible. If everything we listened to had sounded the same I don't think that the 8 participants involved would have sat, unpaid, listening to the same sound over & over again and imagining the differences for 5 days!
