Quad ESL-63 [Template]

Short story - A customer traded these in a few months back.  They sat in the corner of our warehouse wrapped in the original bag they arrived in.  They were finally in the way so we got around to unpacking them and testing them.  That ending my work day....or should I say started a long listening session.  I was expecting the typical airy open soundstage slowly morphing into that thin feeling Martin Logan sound, especially since they here half the size of most of the ML's we have here.  Never have I heard an electrostatic sound like this!  Low end!  Mesmerizing and honey smooth female vocals!   Clarity that bordered distracting as I heard fingernails coming off of strings on tracks and instrument cords and drum kit brackets ringing!  They are so neutral, so free of ...well... speakers.  How come I'd never heard these before?  Maybe I should keep them?  Then thinking what my wife would say, I resorted to taking the pics and writing this ad :-(
I try to post listings without too much emotion so I apologize.  These played clean with no buzzing.  I was able to clip them at moderately high volume but any experienced electrostatic owner knows they don't want to go loud.  Or at least I've read the ESL-63's have the lowest measured distortion of ANY loudspeaker ever measured (from the Internet so it must be true). Maybe it was loud but my mind could not discern the typical cone break-up and distortion associated with traditional loudspeakers.  Anyway, I'd say it doesn't matter what speakers you own, you need to have a pair of these just for reference.
I see a lot of rebuild pairs and parts out there but from what I can tell this pair is in excellent condition.  The grills are clean with no holes or tears.  The bases look new.  The play beautifully.
