Back on topic, it would be good to hear from users of the new Merrill GAN amps and their comparisons. Our reference class D being the Mola Mola Kaluga’s at £9,950 per mono pair, expensive enough but much better than other class D amps we have tried and they compare very favourably with some class A amps costing £50k. The new Merrill’s at more than twice the price ought to be better, that would make them very interesting if price is no barrier. Compatibility with a top dac is a concern with the Merrills, it doesn’t look like Merrill has a top flight dac on offer, if I’m not mistaken. The Mola Mola Makua dac works so well with their amps.
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.)

Anyone listened to or own any of these amps?
