i own the quad esls, i owned the 63s, i have auditioned the 988s and 989s.
i find that solid state amps rob the electrostatics i have mentioned of warmth and body.
i have auditioned the 63s using some ss amps, and prefer tubes.
if you are intent on purchasing a solid state amp. you might consider other amps, e.g., class a, or "darker" sounding ,older amps.
