Class D

Poor George.

If Class D was as bad as George ever claimed, he wouldn't have to be in every single Class D thread.  He's in every thread because class D is seriously good and it bothers him greatly.

Otherwise, we'd all hear it.  We would all know it.  We'd listen for 30 seconds and shudder. 

Dream on Eric you have no ears, it has problems, and Techincs have gone the distance in the SE-R1 in curing one of them it with 3 x higher switching speed (1.5mhz) and so 3 x higher low order output filter, as not to introduce any phase shift down into the audio band, without the need to increase any global feedback as some do, which we all know, large amount of feedback is not a good thing.
Also Class-D has problems with low impedance loads, that’s why you never see independent tests showing the 2ohm wattage almost doubling the 4ohm wattage. Even the Technics SE-R1 still has this problem. You have no idea!

The H2O does it easily, that is drive 1-ohm Scintillas, not necessarily double down to even 2-ohms as no such spec is given by Henry. It uses a linear power supply, but it can't be as simple as that. It must be of some good quality and design.
And it does it with old ICE modules no less! I would look forward to henry's design of a Purifi version but he's hardly in this business as it is.

that is drive 1-ohm Scintillas

Yes many can "handle" but have pitiful current, because some even have trouble equalling the 4ohm wattage with a 2 ohm load, let alone trying to double. Some even go backwards!!
And as for 1ohm, again they might "handle" it without it dying.

But compare it to a Classic Krell or similar and see which sounds better at 1ohm or 2ohm!

That's why you'll never see independent measurements on Class-D showing it can "almost" double the 4ohm into 2ohm and again into 1ohm from 2 ohm.

Cheers George

Georgy porgy with his ongoing illogical attacks on class D born out of ignorance. You really would look less foolish if you educated yourself Sun"don't"shine.
