Maybe I can get ESL57 electrostats. I now use Magnepan magnetostats with T-Amp or TA2020. Without problems. Therefore my question: is a T-Amp and/or TA2020 Evaluation Board stable enough to drive the ESL57?
I use two sonic T -amps to drive my Martin Logan Aerius i's in a biamp configuration without any problem. They do run out of steam if turn the volume up too high. But for all normal listening they are fine.
