The recent PNW Audiofest Show was lightly attended. I took advantage
of the downtime and spoke with Michael Borresen at length. He was very proud
of his new 200wpc class A amp. No Heat. $70k. When I asked how this could be
he said it was all about the parts used and attention to detail in the build. He holds
a patent on the only speaker using no iron. At $30k they don't come cheap.
