I sold Advent product in the early days..and remember many, many things about Mr. Kloss and his ground-breaking products.
At the audio store I worked we would compare large Advents to the Yamaha NS-1, Dahlquists and the ESS AMT-1 with the Heil driver....often to have customers like the Advents best!
Once, at the CES in the Drake Hotel in Chicago, I had the pleasure of seeing a videotape (1" Sony?) on the prototype of the Advent Videobeam at 1:00 AM with several of the people from Advent.
Mr. Kloss was truly one of the greatest in the audio/video world. For us audio lovers there is much we owe to the likes of Nelson Pass, Mr. Conrad and Mr. Johnson, Mr. Johnson at ARC...and (thank God) so many more,...but to none do we owe more thanks than Henry Kloss.
Without Mr. Kloss and his Large Advents...the high-end would not have evolved as it did.
