has always been with tubes. And by best, I mean "most faithful to the music", not merely the loudest.
First in 1974 with Tympani IIIs tri-amped with Audio Research tubes on the mid and top along with a Crown driving the bass panels and at Sea Cliff ten years ago with HP's 20.1s driven by Joule Electra Rite of Passage amps.

Have you heard the Magtech? Just curious, everyone seems to rave about it.
Given its CODA roots as another Threshold offshoot, I suspect it would be a nice clean SS design that would lack the kind of midrange focus I prefer.
From what I've heard with external power buffering, the big advantage of a regulated power supply would likely be in high level transients that get compressed when the power to an unregulated amp sags. I've run 10 gauge cable in a dedicated line but that can only do so much.
I've though of putting tubes on my midrange drivers which will be absurdly efficient once the Neo 8's are in, though I'm leaning towards the little Pass, with my A-21 on the bass -- though I may end up splitting and bi-amping the bass panels, in which case I'm no sure how I'll power them.

Makes sense. On the other hand, having 500 joules of energy storage my VTL amps provide goes a long way!
Similarly, I feed each amp with a dedicated 20A line and a 10 gauge Harmonic Technology cord. :)
I was originally thinking of running my amps on 220V to halve the voltage drop and take advantage of the balanced power that the power company so kindly provides, only to discover that the cheapskates wired our house to 2 legs of 3 phase commercial power, so we have only 208 volts and it doesn't even cancel completely. No wonder I had video hum here in the days of CRT monitors. Had a terrible problem with that in a video facility I built once -- we had to enclose the computer monitors in mu metal shields.
Speaking of balanced - well in a different way. I'm enjoying the benefits of using balanced connections with DAC and pre to power.
I envy you! No balanced out and since I have my HTPC in another room to minimize noise, It's going quite a distance. I had serious hum and had to use a ground lifter. When I have a chance I'll go down the basement and swap breakers to put them all on the same phase . . .
