GaN-based Class D power amps
The use of GaN-based power transistor tech is now emerging for Class D audio power amplifiers. Seems appropriate to devote a forum thread to this topic. At least 3 companies have commercial class D amps in their books:
Merrill Audio, with their model Element 118 ($36k per monoblock, 400 W into 8 ohms, 800W into 4 ohms), Element 116 ($22k per monoblock, 300 W into 8 ohms, 600W into 4 ohms) and Element 114 (coming soon).

ADG Productions, with their Vivace Class D amp ($15k per monoblock pair, 100W into 4 ohms). (The designer emailed me indicating he has another product in the pipeline.)

Technics also has a lower priced GaN-based class D integrated amp in their catalog:

Anyone listened to or own any of these amps?

Some more info that come to the net, also i may have mentioned, that TI Texas Instruments (who also own Burr Brown) have now the rights to manufacture GaN semiconductors. Looks like now Analog Devices getting into the manufacture of the GaN technology. https://www.analog.com/en/applications/technology/gan.html Cheers George |
though not relevant for HEA applications. Think your wrong there, we need to look beyond the forest to see the trees. The whole advancement of "affordable" hi-end GaN based technology Class-D amps making an impact, hinges on who will start making the "component level" GaN semiconductors. So yes Analog devices and Texas Instruments making them is relevant to this thread, as if no BIG semiconductor manufacturers pick it up, you won’t have affordable GaN based Class-D amp to purchase, they’ll all be $10K+ Cheers George |
