ESL 63 and US monitors have an intentionally benign impedance curve that is nominally 8 ohms an is rather flat compared to other electrostats. The lower the output impedance of the amp, the better.
tube amps and electrostatics
What kinds of experiences have people had mating tube amps to electrostatic speakers (full range and/or hybrids)? I love the sound of both separately, but am concerned about the reactance of electrostats with tube power. I already own the CJ CAV-50 and am looking to upgrade my speakers with something in the $2500 range. Thanx, Dave
