Class D

Gotta say, the energy and vitality George brings to discussions about Class D makes it seem rather personal.  As if Class D killed his dog, and he is John Wick.

If Class D was even 10% as bad as he makes it out to be it would be a non-issue.  Class D would be dead and none of us would listen to it, and no one would need to bash it. It would be it's own worst enemy, and attract flies and locusts whenever anyone turned a Class D amp on.

But yet, here we are.

If Class D was even 10% as bad as he makes it out to be it would be a non-issue.

You are the rumour spreader, not once have I said Class-D is bad, if fact I’ve praised the Hypex NC500 with linear power supply monoblocks (given the right loading) that I own in my second system. Class-D has yet to reach the same sound quality as good linear amp in the upper mids and highs.

What you need to get right, is that I say Class-D the way it’s used (except for the Techincs SE-R1) has problems that MANY hear in the upper mids/highs, the deaf may not hear it.
And this is a long way being fixed in the Technics SE-R1 by having a 1.5mhz switching frequency/low order output filter instead of 400-600khz as all are today.

And those that are, or going to use the GaN transistor technology have the chance "to use 1.5mhz", but don’t, probably because they don’t have the R&D knowledge skill of Technics behind them to do it.

And btw Cyril Hammer was the first to say this, even before GaN transistors were released to the market. And has more solid state knowledge in his little toe than some "tuber" here saying anything else.

"if you want to have your Class-D product performing at the cutting edge it is not possible with todays known switching technologies. In order to come close to the performance of the best linear design we would need high-current semiconductors that provide switching frequencies of several MHz or even GHz."

Is vitality code for dementia?

while they sounded fine, they did not have the depth, or crunch of a nice class A/AB amp.

 high priced amps are paying for the same old routine.
Crown makes great class D amps, as does QSC, your paying for the name and advertiising, not sound.

 get a nice class AB amp and have enough power and great sound for 20 years!

 even my old class H amp would smoke any class D amp made.

 dont believe the advertising, and smokescreen reviews.

Correct, if you want big Class-D wattage at 4ohms the get a Behringer 6000watter for just $599USD! for 6000watts! With DSP!!!!
