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?

amplifier - but because dynamics, texture, transparency advantage over mainstream low sensitive speakers. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Yep Box xover types had their day in the sunshine, Clouds are forming, Ck out the xover box used speaker listings,, likea grave yard,, where in 2 yrs you will see lots on unsold Zu and Tektons just sitting, day after day, week ,,month.... sad, thats suffering. My FMS aint going no where, A 2A3 dual tube amp is on the way. My Dual FMS is going to get a nice match. $550+$350 35 lb speaker.

~~~Wife Friendly~~ as a  huge bonus.

A couple years ago considering class D for summer amp replacement for my 845 space heater. Did much research looking for any and all comparisons to SET. While some were positive about class D, the ones that caught my attention were those with high efficiency speakers. The one commonality I observed in those cases claimed there was some loss of texture with the class D. Now, I'm not sure if they're talking about timbre or micro dynamics, perhaps some combo of both, but either way, I find this is special quality of SET and my horns. I don't hear my tubes as tubes, rather I hear them as what the Brits call them, valves. These valves breathe as flesh and blood beings. no SS device can match this special ability.

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.
