They were a hit at last year's Rocky Mountain Audio Fest, so I asked Bob Cordell (resting his dogs in the photo), Peter "PJay" Smith, and Darren Kuzma to give a repeat performance of their seminars on amplifier and loudspeaker performance at HE2007. These ran throughout the Show, and I kept being stopped in the corridor by audiophiles who would say something like "Now I know what tube amplifier clipping sounds like" or "Now I know what is meant by 'dynamic range.'" I was reminded by something I had been told years ago, perhaps by Jon Iverson: that the only difference between an audiophile and an ordinary person is that the audiophile had a mentor who showed them how to listen. Bob's, PJay's, and Darren's efforts will create many, many audiophiles.

Stereophile sponsored the seminars and provided the room and furniture, as well as my personal Ayre C-5xe for use as a source, but Ray Kimber is owed a large "thank you" for supplying cables and for helping with expenses.
