Is D-Sonics audio still in business

@yyzsantabarbara not all GaN amplifiers are Class D. Take a look at the Gold Note PA-10  I have two operating in Bridged mode with an SPL Phonitor 2 as a preamp and they are spectacular.  

I also agree that the Bel Canto products are well built and sound great.

The PA-10 features quite an interesting design. It is not a Class D amplifier but it leverages a new technology that uses MOSFETs for the output stage, in common with the Class D, featuring an output oscillator (GaN Mosfets with Gallium Nitride), a proprietary design that actually doubles the power of the amplifier when reducing the impedance – exactly as a pure Class A but with extremely high efficiency to deliver great amounts of energy.” So there you have it.

What may surprise you is despite its great power for such a small box, it's not a Class D amplifier.  

"It's actually an A/B amplifier, but it uses a switching mode digital power supply, which allows it to get more power in a smaller chassis,"

@alucard19 I do not own the DH Maria amp. I just linked to it because I think it is the same design as the PeachTree GAN1. The GAN1 is $1500. I have about $600 mods on top of that. I think it is a rather great amp just hindered by the limited connectivity and the SPDIF requirement.

I expect other companies like DH to follow a similar design.

@recklesskelly I learned something new about GAN and Class D.

A Purifi based amp might be what you’re looking for. I have a March Audio amp (P502, discontinued) and am a fan of their build quality and incredible sonics, but they’re based in Australia. If small size is what you’re looking for, then you don’t really need monoblocks, and the P422 might fit the bill.

Even cheaper would be a Hypex based amp, and for that I would go to Audiophonics in France. Look for the NC502MP module, it’s 500 watts into 4 ohms, plenty of power and for many is indistinguishable from a Purifi. My amp is based on that module and it’s mighty fine and powerful, incredible detail and clarity with great bass drive and definition. I love it and don’t feel a need to upgrade to a Purifi at the moment.

Another vote for Bel Canto. 

I have a Nord Purifi dual mono Class D amp which I rate as excellent value and SQ. Mine cost under Aust$3000 including shipping from the UK to Australia, customs duty etc. They also do cheaper single end Purifi amps and Hypex amps as well as more expensive Starcrimson amps. In the USA I believe Buckeye have a good reputation but extensive waiting time.
