Digital input amp

This technology HAS NO DAC.

@tvrgeek If this is so, then the amplifier is not also class D. Class D is a very specific class of operation. Since you apparently have a degree, then you know that class D was proposed in the 1950s and the first home implementations were sold in the 1960s. You also know the building blocks required. So pick one: if its class D then it has a DAC built into the same box to which the digital signal arrives prior to the class D circuitry and probably one the same board as the class D section.

If this is false then its not a class D amplifier inside although it might employ switching technology.

Thank you Ralph. Much like the Gold Note PA-10 that employs switching technology (their version of GaN) and is not Class D as some of the  audio journalists have misstated over the last couple of years (Darko). 

If this is false then its not a class D amplifier inside although it might employ switching technology.

Of course the OUTPUT stage is an integrator. I said so from the beginning.  Gad how some here want to be so superior.  The entire point is this is a new technology worth watching as it changes the entire string. The Peachtree Gan1 does not have a traditional front end DAC.

I also got some comments from the local dealer who has heard this unit and they suggest it is not quite ready for prime tike.

I think users here are just trying to be accurate. You choose to take it personally that your claim has been questioned:

They take a USB or other input. No DAC on the front end. Just the DSP engine to do volume, eq, etc, then whatever conversion to PCM to feed the class D output. So the only "DAC" is the output stage.
