SET the best?

Is SET amplification where we should all end up? I keep reading posts where people tell of their journeys from plenty power to micro power, and how amazing SET amplification is 45 set 211 set 845 set otl, and usually, ....with the right speaker. I have yet to read of anyone who has gone the other direction from SET, to High watt beast class A amps or others.
If your speakers can be driven by minimal wattage, is this the most realistic, natural sound we can achieve? versus say, 86db sensitive speakers and a 1000w amp?
Is the end result solely based on speaker pairing? circuit? tubes?

I am in the process of changing my direction in my search for realistic sound, just because, and wondering if this really is the best direction to be going.
From what I have been reading I think it may be.

What do we get with SET? What do we give up?

What's you favorite color?

The price of the Audion is $7500 Pair, we did not change the price since January 2020.

Hello,

absolutely I need to confirm the GaN Fet AGD uses for the Audion, Vivace, and Tempo (either in the AGDGaNTubeKT88MKii or in the new GaN power module for the Tempo) were optimized specifically for Class-D application hence for Audio.

The article of Rick Backer is therefore perfectly correct.

I cannot disclose the name nor the products of the 2 very large customers these chips were originally intended for (customers of International Rectifier), but I can confirm these were 100% audio applications. The current GaN-Fets available today from many suppliers are indeed designed and specified for Adapters and Battery charger (pc/tablet/phone) applications, and they have therefore different characteristics (very different) than the one we are using. To use them in Class-D is possible of course, but several additional layers of circuit design optimization are necessary.

Hope this closes the case about the truthfulness of what Rick Becker reported.
