Class "D" amp? I do not have a clue. Do you?


I have been a serious audiophile for 30 years and class "D" audio is new to me. Most important, what do they sound like?

I too have had Bel Canto's Ref 1000's in my system. IMO their power and overall presentation seem very well designed when paired with my Eidolon's. In the June / July issue of TAS Nelson Pass gives, what I consider, an experienced and gracious opinion of class D amplification. Unfortunately, like countless other opinions it generalizes these designs as well as assuming the goal of these designs is to achieve "the qualities of good class A amplifiers."

Class D switching, digital, PCM, ICE, etc. amplifiers come in a variety of implementations. Many share some fundamental design features, still, most seem to have their own distinguishable presentation within class D. None of the class D amplifiers I've listened to at any length sounded like a push pull or SET tube, solid state, class A, AB despite others claims.

As a professional Bass player I often play raw digital pre production files as well as analog recorded tapes. What my switching amplifiers do for me is provide an unbelievably revealing and transparent presentation ( what could easily be termed as sterile ) and the most well defined bass. I've found their most unusual quality is their ability to preform at their full output capacity without becoming congested or fatiguing. It's as if they're passing current directly to the drivers. In short they sound like switching amplifiers and their presentation is not for everyone.

My suggestion is to do your own auditioning using robust copper interconnect, speaker, and power cable and an up to date dedicated and shielded AC circuit. Switching to a battery powered preamplifier took my system to another level altogether.
