Absolutely,I started with his gear with a 400a and my last was a Sit2,and had many of his designs in between.

Just a genius and brilliant amp designer that’s still fulfilling his passions.

First Watt F7 made a believer out of me:  Zen Master Pass.

+1 to kdude's accolade.

His 1977 A20 driving Quad ESL57's made me a believer, so much so, I morphed that amp into a massive 2 man lift pure 150w Class-A, that was water cooled, own pump, radiator, and cooling fan.

I was introduced to his expertise way back in his Threshold days with owning several of his amps...and have since settled into enjoying his Pass X2.5 Pre and 250.5 amps ... Pure enjoyment !
