Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???
Hi Singingtheblues, I have listened to Devialet several times at RMAF, including I believe the 250.... I am not surprised that eventually you found it to be grating.... The overall house sound is certainly open, but a little too treble-happy for my taste... Some small amounts of treble hardness may have been traces of intermodulation. Regards, G.

It will be several years before this GaN class D audio amplifier IP technology becomes truly affordable. I don’t believe so, EPC have already sold these to several Class-D manufacturers direct, and Digikey are already selling it, it doesn’t take much, just demand for a major semiconductor manufacturer to step in and purchase the right to make them for the masses, it’s like the Power Mosfet all over again, which they developed, and became the norm in no time at all. https://www.digikey.com/catalog/en/partgroup/ganfet-gallium-nitride/53212 Or you can buy the complete Evaluation Board and put it in a box. https://www.digikey.com/products/en?%20WT.z_cid=sp_917_0110_buynow&site=us&lang=en&mpart...

It’s my understanding that there are currently 2 leading producers of high-speed GaN power transistors, EPC and GaN Systems. Does anyone know if there are differences between the two of them and whether GaN Systems has a proprietary patent on their GaN FET transistor, too? Are there other producers of currently available GaN transistors with unique patents? Are there other producers of currently available high-speed GaN FET drivers besides Peregrine and their PE29102 driver? I’m just trying to better understand the companies and products involved in these emerging markets. Thanks, Tim |
