I was wondering how these amplifiers behave with Quad electrostats. I have always powered those with Quad amplifiers (and have been happy doing so). My idea was that given that these speakers present a rather different kind of load, powering them by an amplifier designed by the speaker's designer was a good idea. However, I think my Quad 2805s can do with a bit more power than is available from my refurbished Q606-2. I could get a a pair of Quad QMP monoblocks, but these are both quite expensive and not exactly frugal with electricity at a moment that I am trying to reduce my ecological footprint.
