set vs otl, which is the most musical


Set and otl amps are almost opposites in terms of many aspects of circuit design. Which of the two designs is the most musical (define musical in your own terms as there is likely not to be a universal definition acceptable to all). Which do you prefer and why?

I agree with Acresverde. (I started to explain but determined that I can't say it better than Acres.)

I've owned only one pair of SETs, Antique Sound Lab Explorer 805s, that drove 86dB-(in)sensitive Quad 989s. As I don't listen at high levels, they and I matched very well until I tired of the 989s' treble balance and changed speakers.

But with a single output trode per channel, power output of an SET is always an issue unless one has very sensitive speakers. Mine are the opposite (at 84dB sensitivity), so I've opted for all trodes but lots of them, in the form of ASL Hurricanes in triode.

If I win the lottery, I'll buy a pair of 140-Watt Atma-Sphere MA-1s and keep one pair or the other. I love my ASL 'Canes, but maybe those OTLs will sound a little quicker, cleaner, bigger, etc.
