Edge NL-10 Stereo Amp Utilizes Edge's Proprietary Laser Optical Bias Circuitry

$4500.00 includes shipping! This amp was a trade-up for our Merrill Audio Veritas Monoblocks.  
The unit is in mint condition, about 8 years old. You cannot tell it is 8 years old. Serial No. 102263
Don`t have the original box, however the substitute box is built like a tank and just about the best box I have ever seen.

Technology:

The NL series of amplifiers utilizes Edge’s proprietary Laser Optical Bias Circuitry. This new circuit incorporates a 630 nm wavelength laser in each channel operating directly on the silicon substrate of the bias transistors. The laser bias circuit in turn is part of a servo feedback network. As the signal rises, the output of the laser increases, and as the signal decreases the laser output falls. This keeps the bias at the optimum operating point allowing a tenfold increase in gain. The additional gain is achieved while maintaining signal integrity (linearity) -- at light speed -- a first for solid state amplification. The result is the clear musical nature of the NL Series as observed by well-informed reviewers and buyers.

The NL series also features oversize binding posts and up to 16* low-leakage snap lock 10,000 µF caps per channel. Also the new low-leakage / low-field medical grade transformers are housed in magnetic stainless steel enclosures for non induction and low noise performance. Chassis construction on these amplifiers is 1/2” thick 6061 aluminum, held together with marine grade stainless steel machine screws. Heat sinks machined from solid 6061 bar stock keep transistors cool without fans. The output stages utilize up to 32* N channel bipolar transistors for extremely low output imedance.

The NL Series amplifiers are built on a solid base of experience gained through many years of field use with the AV series of amplifiers. AV series amplifiers share the same rugged construction and attention to detail found in all EDGE products.
