I've owned a lot of Carver gear since 1986 and they were excellent in both sound quality and reliability. But it's fair to say that his products evolved and that his engineering genius and passion could occasionally outpace his business sense.
I've owned four Sunfire Signature amps running (now restored, they lasted over thirty years before requiring a rebuild of the Bohlender-Graebner Ribbons) a pair of Plat Amazing Loudspeakers (w/outboard custom-designed subs) multichannel system and they are the best Solid State amplifiers I've ever heard. (And I own a number of the Mac amps that inspired them.) His tube amps are something with which I have no experience besides having heard them in other systems. They sound quite fine, even on challenging Telarc Organ recordings with first-octave Bass. The Carver Corporation A-series amps are close to the same designs as the Sunfires. (I.E., "Light Star"...) If I were seeking out a 75wpc tube amplifier, I'd probably look at a McInlosh MC275. The hyperinflation in High-End Audio is doing serious damage to the future of the hobby. The industry needs someone like Bob to bring the "knee in the price/performance ratio J-Curve" back down to Earth.
