Guys, first, thanks for the compliments! I started Digital Amp Co in 1996, and that was after about a decade of amplifier design, including Class-A, Class-AB, Class-G, Class-H, and several variations of Class-D (analog in, digital in, analog modulation, digital modulation, open loop, closed loop). I’d like to think the experience, hard work, and sound (pun intended) engineering practices has produced what will someday be referred to as the best sounding amplifiers in the world.
Second, modern Class-D designs vary wildly in topology and implementation. Unfortunately, the biggest market segment for Class-D has been cost centric. Some of the sonic problems with the “old” Class-D carried over from the old stuff to the new stuff, namely modulation techniques, control techniques, and general topologies.
Third, reliability wise, Cherry Amps have been out there for about 12 years now, and our reliability is amazing! There are hundreds of Cherry Amps still powering systems reliably after more than a decade of use.
Fourth, we do things differently. There’s a reason that most Class-D amplifiers on the market are pre-fab module based. Class-D design for super high performance is NOT easy. Engineers with decades of analog amplifier design experience have tried Class-D designs and failed miserably. I hope to add more to this thread later. Thanks, Ron, for starting this very interesting topic (:
