Zszwedo, OTL are just amplifiers. Like all amplifiers, they work with some speakers and not others, and some OTLs sound better than others.
People often talk about OTLs are like they are somehow something 'other'... but they compete quite nicely against traditional amplifier designs. If you like speed, transparency, neutrality and smoothness all in one place they can be a good option.
Tube amps in general need more attention than transistors. Some OTLs need a lot of attention. Ours tend to need very little- bias is automatic and the amps are quite stable- more so than most 'conventional' amps.
However in my last post I was not talking specifically about our amps, but they do work well on JM Labs. Our amps tend to run a little hotter, not (as most people think) because of the tubes, but because they are class A amplifiers.
