This is the same exact amp as the Bryston 3bst, its made for lexicon by Bryston. This ones in mint condition and I just purchased it two weeks ago from my local dealer as a demo model..Retail was 1800.00 and it bests all the amps I have had in my home (over 25 all together)..Circumstances dictate that I sell it. I dont have the original box but will double box carefully. I have over 86 postive reviews on ebay with no negatives under my email name...PRICE IS 800.00 and thats SHIPPING INCLUDED in the Cont.US as well..Please email [email protected] if interested. Specs: NT Series: New sound sources and digital formats, especially those associated with home theater, are placing greater demands on power amplification - to the point where Amplifiers designed for music are increasingly inadequate for reproducing audio/video soundtracks. They simply lack the necessary combination of clarity and brute audio power to faithfully re-create film dynamics — a situation likely to worsen as A/V sound sources improve. This is why Lexicon has developed the NT Series of THX Ultra®-approved power amplifiers. The huge reserves of power in the NT amplifiers provide more than ample headroom, and are perfectly suited to support the extended dynamic range inherent in these new formats. The vanishingly low noise of these amplifiers assures the quietest, cleanest power imaginable, while their awesome authority results in precise control over any loudspeaker. NT amplifiers have been designed and manufactured for absolute linearity and stability. Utilizing a unique of connections and configurations are accommodated, as well as unique features specific to complex multi-channel audio systems. We believe that an amplifier’s goal is simple: to amplify the signal, accurately and cleanly, into any load, without imparting any coloration or distortion. Indeed, the distortion components of the Lexicon NT power amplifiers push the limits of sophisticated test instruments. More significantly, their sound can best be described as utterly neutral. While the amplifier’s goal is simple, its job is not. Over twenty years of amplifier research and design have resulted in products that perform flawlessly, year after year. Sophisticated engineering, manufacturing, and testing are combined with meticulous craftsmanship and pride, so you can enjoy the music and the movies — and forget about the equipment.

The NT Series Amplifiers have been designed for absolute linearity and stability. Utilizing quad-complementary output stages, they produce less distortion than even Class-A designs, with higher efficiency and better long-term reliability. A wide variety of I/O connections and configurations are available, as well as unique features specific to complex multi-channel audio systems. Approved for THX™ Home Cinema installations. Standard Features: Remote 5-15 volt trigger sensor Programmable Power-on delays signal ground lift RCA, XLR and 1/4 inch input jacks Bridgeable Exceptional AC line filtration Ultra quiet Separate power transformers for each channel Legendary reliability Completely neutral sound The NT 212 Power Amplifier The 212 contains two 120 watt amplifiers (200 watts into 4 ohms) which can be bridged to provide 400 watts. With its ample current reserves, the 212 can be used with most stereo speaker systems, or two can be used in a bi-amplified two-channel system.
