Sound Lab Ultimate 745 in excellent condition

Lighted used dealer demo version U-1 PX with latest base focus technology.  The U-1 PX not only incorporates Sound Lab's latest
electrostatic panel and electronic technologies, it also incorporates a massive
steel frame to protect and preserve the critical tolerances of the
electrostatic panel. The heavy duty frame employs three-inch diameter steel
support posts that are solidly connected together with 1/2" thick steel
brackets, terminating at floor level with spikes for solid floor coupling. The
high reactive mass of the framework eliminates frame vibrations, thus
eliminating frame resonance and insuring that all sonic energy is converted to
music.  Further, the U1-PX includes
Bass-Focus technology that increases bass dynamics by more than 6dB.
