Selling my ultimate Electrostatic Solutions 57's! Using super heavy 2-3 inch think custom hard maple frames, they take the weight and rigidity to a whole new level. Tighter focus deeper bass, faster transients. All redone ES panels with super light mylar film that is a fraction of the thickness of the original Quad's, the speed is instantaneous now, with no "plastic" whomp to the bass anymore. All new upgraded electronics all spec'd as original. IEC power cords new cardas binding posts. Front feet spiked at the same height as original feet. In the back is a single infinitely variable spiked leg allowing totally fine tuning of tilt angle, using a maple knob. Want them straight up no problem want them with 2 degrees of tilt not the factory 13 degrees no problem. This speaker is tonally identical to the original 57! However it cannot be destroyed due to the ES protection circuit, (not in the audio line). The extra bass extension and bandwidth make this the best speaker you will ever hear. I am only selling my personal pair, as I embark on a new stacked 57 project with Kent McCollum of Electrostatic Solutions!! Available for audition in NJ. Shipping will require freight and a pallet. Any one can read the Robyatt Audio show reports about the 57's we used. Well this version of the 57 is the ultimate extension of that sound. If you love Quad 57's this is nirvana.
