I have just acquired Quad 989's Electrostatic Speakers and I find

the ultimate and definitive solution, at least for me. I currently
use
entirely Quad units to drive them, i.e. Quad 909 with its pre-amp
together with a Quad 99 CD Player. However, I noticed one US
reviewer
of the speakers stated that while the 909 Amp must have been
designed with the Speakers in mind he found that he got the best
results with other amps, is this true and what therefore do you
consider the "best" setup to drive and to use with the 989s.

They are designed for the Quad II-forties and QC 24 pre amplifier
