High end Class D amps?

And there you have it folks.

Throw the old dog a bone and he chokes on it. Georgehifi has clearly stated he is unable to explain how EPDR will impact a Class-D amplifiers ability to drive a load. I hate to say I told you so, but I told you so.
Hint to the old dog, there is nothing in that article that relates to Class-D.

Do you even know how to read an SOA graph? I am going to guess no. You don’t understand this graph:

In a Class-D amplifier, the voltage across the device is effectively 0 (or close to it). That means the devices operates on the graph effectively on the left vertical axis at 0 volts. The limitation is pretty much the device current rating. Practically it will be a bit to the right of that as there is dissipation due to RDSon and partial conduction for nanoseconds while switching.

Funny you can find tons of time to attempt to bust every Class-D thread and to chase fusers ad-nauseum, but you can't even put a few of your own words together to explain why EPDR could matter to a Class-D amp. I know why you don't. It is because you can't.  You would rather bash Ralph from Atmasphere and others not here to defend themselves with falsehoods. That is not honest behavior.

And there you have it folks.

You have nothing but your ignorance and being a fuser, and your persistence in the future shilling of whatever Class-D project you seem to have, could be with an old OTL maker the way your so persistent with wrapping him in cotton wool.

It seems whenever “Class D” amps are mentioned they brought up a bunch haters. They are relatively cheaper to make and they don’t look as impressive as Class A amps for sure. They typically come in smaller package and are way too light compared to those expensive Class A monsters.
Regardless how they sound, they just don’t feel high end enough to some. I have owned Krell Class A monoblocks, BAT tube monoblocks, and Vincent hybrid monoblocks before. Currently I’m breaking in a pair of PS Audio M1200. So far I really like them. 
Monoblocks sounded better than stereo amps that I agree. 

Please come back and let us know after you’ve lived with them, as from what I’m told they are the ICE 1200 modules like @tweak1 uses (he’ll be happy) but with a tube input buffer.
Look at the graph and say if you can hear a disconnect of sound signature with the phase shift above 1khz.

like I can with my big linear phase ML ESL’s with Neolith panels

Oh george, now you are resulting to lying.

Georgehifi  CAN NOT tell people here why EPDR matters to a Class-D amplifier because he does not understand Class-D, he does not understand EPDR, and he does not understand SOA.   Given his hate for Class-D, if he truly understood these things, he would be all over this given clear, concise and accurate explanations. He does not, because he can't.

And now you are calling me a "fuser". Anyone here can read my posts and readily see that I am not a "fuser". Of course that does not change the fact you don't understand electricity either. "AC" is not an argument for fuses not being directional. It is because fuses are not directional that AC operation is not impacted. It is NOT a subtle distinction.
