A great article on Class D/switching amps


The latest edition of The Absolute Sound has, in my opinion, the best overall perspective and evaluation of the eight most regarded class D switching amps on the market today.

The article contains an explanation of the technology, an interview with a couple of the most important designers, the individual reviews and finally a round table discussion regarding these amps.

I believe any of you GON members who might be considering auditioning a class D switching amp would want to review this piece regarding their different sonic signatures.

I had the pleasure of listening to the Kharma MP150 which the panel picked as being on top of the "heap" compared to Audio Research 300.2,Channel Island Audio D-200, Nuforce Reference 9 Special Edition, Red Dragon Audio Leviathan Signature, Jeff Roland Design Group 201, Cary Audio Design A 306,and finally the Spectron Musician III.

Each amp had at least two different reviewers with different systems evaluate them and then compare their experiences. This was a well done piece and if you read it I believe you find it both educational and helpful to understand what these amps are all about.

Most of the music hangs out in the midrange and is a critical area where digital amplification doesn't seem to address as well as analog. Besides that they (Class D) fail to provide the texture & harmonics that makes music an enjoyable experience. Yes they get alot right and may be our future but they are currently work in progress as some have agreed. If I were to settle on a Class D amp it would have to have an analog power supply.
Tbg, keep in mind my above statement is strictly a matter of opinion but you probably already know that there are currently some digital amps that employ an analog power supply and some prefer it. It is unbelievable how much marketing hype there is behind some digital amps. At first, after reading some of it, this left me feeling that my analog amp was outdated technology. As some audiophiles unload their analog amps there will be many waiting in the wings to grab them up.
Muralman1, you are right as rain, excellent point. I myself have determined that an oversized power supply has provided more depth on some gear I have owned.
