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.

I'm using a Tact Millenium class d amp since '99 replacing at that time pass aleph 2 mono blocks. The tact is different to the newer designs. I directly converts PCM to PWM so no DAC needed. Volume is adjusted by adjusting the voltage which is been switched.
in 2001 I had high a friend with a very high end system: 12K transport (TL0) going into AN DAC 5 limited edition, preamp was Conrad Johnsson Art and amps with AN single ended Keigon mono blocks driving Wilson MAXX speaker. Once took my Millenium over to my friends place replaced all that very expensive tube gear (pre/power and DAC). To my and myfriends very surprise that tact sounded extremely similar to the tube stuff!
Got the amp modded recently and extremely happy with dring my Omega DUOs.
