Martin Logan Summit X Electrostatic Loudspeakers [Expired]

no longer for sale

I'll admit, I'm not a big fan of electrostatics.  They seem 'light' after a few days and I miss the dynamics of cones, however during 'testing' and set-up of these I found myself listening to music for hours.  Whatever Martin Logan did with these panels, they need to keep it up!  Huge soundstage, yet the panels are not overwhelming in the room.  What blew me away is the amount of bass... and the accuracy at which these speakers delivered it.  They can produce a very convincing large floor standing, conventional cone driver sound, yet with the open and wide sound of a flat panel. 

I've used Jacintha's Moon River track for many demos.  She's singing acapella in a sound booth.  In the next room, someone is playing a single note on the piano to keep her on key through her headphones.  If you listen close on a really good pair of speakers you can hear the notes, through her headphones.  You usually can't hear the notes until a minute of so into the song.  With the Summit X's I started hearing them right away!  I even heard her facial movements, lips and tongue like I had not heard before (hope that didn't sound weird).  (We sell 6 figure speakers and we hear a lot of great stuff).  This was just my experience, but I was impressed. 
The speakers were a local, one owner trade-in and are very well kept.  No smoke, pets or kids and they look like they are nearly new.
