D-SONIC SOA Class-D Core Amps. The best Class-D ?

Subjectivity is a wonderful thing. There are traits within both solid state and tube preamps that may never quite match such as harmonic structure. The preference for one or the other is a mater of personal taste.

Consider that, with all the shortcomings of tubes, a great deal of time is spent on designing components to sound like tubes. The day may come but until then if you like the sound of tubes there really is no substitute.

Hmmm...what makes Tube Preamps so special? The bottom line..Tube Preamps exalt at creating an exotic, ultra smooth, seductive, full, three dimensional "FLOATING MIDRANGE", that solid state has yet to achieve until now.
Audio Design Engineer Robert Koch, who specializes in exotic tube design amplification, invented a first time circuit topology called the ITC circuit, known as Inverted
Transconductance Coupling, which eliminates for the first time in a solid state design distortion way below measurable levels, which is one of the several reasons why
Robert's Takumi K-10 solid state Preamp will equal in full
the midrange and treble qualities exclusive to the worlds
finest tube Preamps on the market. Getting off subject. Want to stay focused on Class D topology.

It's the way tubes distort not their lack of distortion. Regardless of how unmeasurable a solid state devise is, generally its characteristic is still odd order.

It's the same with switching or processing amps. Were class D is about to become superior is in the realm of digital playback. A digital source and something like the Devialet were there is much less conversion taking place and the absence of cabling lowering the chances of jitter.

Most linear solid state amplification has a tendency to get congested and more fatiguing as demand increases which is why they build massively powerful amps. The very first thing I noticed with my first switching amp was it seemed to maintain stability right up to its threshold which was way more power than I would ever use.

Since I use tube amplification in my predominately analog system the last thing I want is the switching amps powering my studio monitors to sound like tubes.

Oh..so you want your tube amps to sound like tubes..but you
don't want an analog Class D solid state amp to sound like
tubes..Hmmmm..my..just about any tube fanatic on the planet
would put their tube amp in storage or sell it if a solid state Class D amp
reached a level of full tube quality.
There would be no turning back.

In conversation, Theta Digital told me they're close to releasing a Class D Mono Amp housed in the Expression chasis.
