Those Final electrostatic panels are highly regarded. However electrostatic speakers present a complex load to amps,which cause all sorts of stabaility problems and ringing.
To get the best out of them they deserve a Quad 909, which was deigned to work flawlessly to all loads, especially electrostatics. I would not be driving those speakers with an Emotiva.
There are
two 909s for sale on Audiogon now.
I regard them as the ultimate domestic amplifier. You can see two of them here, they are the two lower amps. The ones above are Quad 405-2s
