Atma-Sphere Class D… Amazing

Just finished reading through this thread that started in 2022. Glad to see it is still running as I have a pair of A-S Class D Monos arriving tomorrow. Unfortunately, my source is in repair - the balanced outputs were thumping. So full appreciation will wait a little while.

System is: Auralic VEGA G2 with LEO GX clock (VEGA is in the shop and using POLARIS in the interim) => Pioneer M-22 => Omega Super Alnico Monitors - HO with a pair of Rythmic 8" powered woofers and a pair of KEF KC62 subs.

The Pioneer is vintage 1970’s all Class A and is wonderful. Just very hot and 50lbs. Still looking for something lighter that will match its sound. From reading this thread and other opinions, I am very hopeful!

More to come.

Meanwhile....

Here’s a pic of my Pioneer heavyweight.

and the system as a whole

Beautiful!

>Does the quote above suggest Alberto (AGD) is misleading in his saying his GANFETis made for audio?" 

Alberto is correct. There is a large variety of GanFET transistors that are made for different voltages and currents and switching times. Only some of them are good for power amps for a number of technical reasons.

GanFET transistors in audio amplifier work entirely differently than let's say bipolar or FET transistors in class A or A/B.

They are just switches, there is no transistor curve involved in shaping the sound like in Class A or B.

GanFET transistor used in class D are just a better faster switches then MOSFETs traditionally used in old Class D.  They produce a more square square wave resulting in bringing out all this magic otherwise lost in the grunge generated by MOSFETs. I wrote an illustrated primer paper on Gan FET explaining the mechanism in detail:

@mihow     There is a BIG difference in saying that some Ganfets are made specifically for audio purposes as opposed to saying some Ganfets are more suitable for audio (read power amp) applications than others. Your post supports the latter...Alberto's post claims the former. What the actual truth of the matter is, I do not claim to know.
