I just wanted to pop in and say I too look forward to first hand listening experiences, as well as direct comparisons with other Class D and other types of 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.)

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

Anyone listened to or own any of these amps?

The Technic SU-G700 listed in my OP appears to lack the GaN FET driver stage of the other GaN-based Technics products. Here is a GaN-based Technics server/integrated amp that includes a GaN FET driver stage: https://www.technics.com/us/products/grand-class-g30/network-audio-amplifier-su-g30.html A review is available at this link: https://hometheaterhifi.com/reviews/amplifier/integrated-amplifiers/technics-su-g30-network-audio-am... |
This is a newer technology, some are very using with mosfets , there are a a lot of good digital out there . In my Amp Danish Gato Audio they use Pascal modules, which BTW Jeff Roland uses and make custom analog input,output sections . That meet or beat most Class AB amps out there. Times are changing very fast. https://epc-co.com/epc/GalliumNitride/WhatisGaN.aspx |
