Does anyone, here, listen to these headphones on an SET headphone amplifier? The 812s don't look like a difficult load. But i am more concerned, not about the power factor, but that the voicing of the headphones may be biased. Maybe that's not a problem with these headphones, since i recall reading a positive response from an OTL user (but on the other hand, they have a high output impedance relative to amplifiers with transformer output stages).
My 701s were easily driven by my Stratus 2A3 headphone amplifier. But they just died on me, unfortunately, and I am looking for something that sounds like them - balanced, cohesive and truthful sounding on an SET amplifier.
They appear not be available in my country (Denmark), only the Pro model.
