Different one. The test vac referred to was done during one of my trips to Holland. The Hawksford test you and I did (it was on phase shifts rather than data compression) was not particularly well-controlled, but a lot of fun.

It's beginning to dawn on me (slowly) that neither of us is quite as deaf or clueless as most people believe. I know it's difficult to believe, but it may be true.

We'd need a good, controlled, double blind test to be sure.

Speak up! Why do you keep mumbling???

As a change from the usual, I might say that I had lunch with Jack Bybee today. He picked me up in the Bentley, but I wasn't as overawed by it, compared to a year or so earlier. We discussed shot noise suppression in an atomic point contact. I thought it was interesting, so did he. It is related to quantum resistors, remember them? Our new power amp design, just passed a direct comparison test at a musical conservatory, to the JC-1's, but at 1/2 the price or less, and 1/20 the heat dissipation. Engineering marches on! '-)

What next, time to drop Feynman's name again YAWN!? Where did you eat? I find Chez Pannise to be getting a little long in the tooth, the Quaker French thing has its limits. They are being very PC and no longer offer a lot of the luxury ingredients. I personally don't care but the usual suspects probably want to nail those goose feet down and look the other way.

Hello John

Whats the name of the new amplifier I will be looking out for it in the market, and will it be under the Parasound or Constellation audio banner or another high end audio company.

By the way would you have photo of the setup at the conservatory, I am sure there are lots of people on this forum besides me who would be interested.

Regards
Arthur

It would be Parasound, if it goes forward. we shall see.

I'll bet it's not a pipe either or a chillum or a hooka.
