I own the Peachtree Gan 400 amp.....Match it with a nice tube preamp and you have a beautiful , musical sound. Nice. OR go with the Pascal Module that Aavik , Axess and Gato have for a step up in SQ.
Gallium Nitride GaN Class D Amplifiers
In my recent research for a possible upgrade to my current amp (Benchmark (AHB2) I was reading about the new higher end design for Class D. I'm very interested in learning more about these new GaN(Gallium Nitride) designs. Three companies are offering some very well reviewed products and they are not going crazy with Watts per channel:
Orchard Audio offers a 250 watt Amp
AGD a 100 watt
Atmos-Phere also a 100 watt
What's interesting is while Orchard is a new company AGD and Atmos-Phere have been around a while producing high end Tube amps. In almost every review it is noted how these newer designs sound like Class A or Tubes with all the benefits of Solid State. One reviewer couldn't go back to his tube amps after extended listening to the Orchard. No wonder AGD and Atmos-Phere are getting into this technology. It's very exciting as these amps are highly efficient turning over 90% of the power they draw into sound compared to about 78% with A/B designs and I believe even significantly lower for Class A. They run cool and usually weigh between 10-28lbs. I plan to do more investigation. Small size and light weight with decent power is very attractive. There are also mono block offerings for more power if needed. These are not cheap Class D products. They are well designed and constructed.
Orchard Audio's base model is around $2700and their Dual mono version with larger power supplies is $5500.
Both AGD and Atoms-Phere are $5000
Mono blocks for each are about twice the cost.
Has anyone had any experience, demos, etc ., with these types of GaN Class D amps?

My Audions are fronted by a Primaluna EVO 400 pre which has been in my stack for 2 years. This sounds good, but in a few weeks supposedly I will be receiving a Holo Audio Serene KTE pre. My DAC is a Holo May KTE, and the Serene is supposed to compliment the May quite well. However, I am a little apprehensive. New Record Day’s Youtube review of the Serene said something to the effect that the Serene took the totally clear window of the May and smashed that window out of the way which is what the Audion already feels like it is doing. Clear I like - "clear light" as in the famous old time LSD could be harmful to your health. LOL |
Just commented on your too heavy to lift thread. Do yourself a favor and just find the right amp. I went the GAN Class D route and now sorry other than it will probably be my summertime amp. It just amazes me how to some people they sound like tubes, or even better. They just don’t. Of course that’s just my opinion like everyone else’s. YMMV. |
@marco1, you have made this comment in different threads. I respect your opinion, and I made a similar decision, but I hope you won't mind if I ask you to share some details. It's helpful to readers if specific Class D amplifier(s) are discussed, because akin to other audio components, chip amps (I use the term chip amps, because not all are Class D) don't sound the same. At least the chip amps I've heard in my system had different presentations and characteristics. Which Class D amp(s) are you referring to that did not meet your expectations? |
