Blind testing? I'm going to guess you're not a "tube guy". ;-)
No. I prefer my music to be undistorted and my amps to be no more expensive than necessary to produce audible accuracy, which in the case of solid state is very cheap. Although I have no problem with people who like the sound of tubes' particular distortion when it's audible. Whatever floats your boat. Just don't call it more accurate. BTW, I have participated in two blind tests for amps.
Roger Modjeski (of Music Reference and RAM Tube Works fame), though a completely "modern" amplifier designer, considered the OTL design of Julius Futterman ...
Is that the same OTL that failed blind testing against a $220 Pioneer receiver in the infamous 1987 Stereo Review test?
Some feel the same way about the Quad ESL, another design from the 1950's
I remember hearing the Quads in the mid/late 80's, but I don't remember what it sounded like. A speaker that did stand out to me at the time was a Magnepan MG-III(?) for acoustic instruments and an Ohm F(?). Magnepan was the only speaker that could fool me on acoustic guitar. No other speaker I've heard sounds "real" with that or other instruments. But if someone was going to give me a set I'd chose Revel Salon 2. Dolby Labs agrees.
