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?

for some reason this site is not allowing me to copy the link to Rick Beckers report on the AGD Audion monos at Enjoy The Music

Spoiler Alert He is very impressed


@tweak1 , make sure when you click on the link icon above that you  clear out the entire field before inserting the link. That may be what's tripping you up as it did to me before I figured it out.

All the best,
