Ex Distributor offering Luxman’s remarkable second generation P-1u Class A Headphone Amplifier, with ODNF delivers state of the art musical performance for the discerning headphone based music lover. New in box. One year limited warranty on parts and labor. Feel free to contact On A Higher Note with questions.
Luxman’s emphasis is on reproducing natural music, with lots of warmth and detail; not frightening it into scaring up non-existent detail, which is sometimes described as etched. Luxman’s engineers are fanatical in their attention to detail; while they spend a lot of time analyzing how components perform on their test equipment, the final arbiter is the listening evaluations. Is the product able to play music, convey the emotion, reproduce the ambience of the venue as well as the timbre of each instrument, distinctly. This is where Luxman shines.
Pure Class A
Luxman has long championed the use of Class A power for its richness of timber and absence of listening fatigue.
Because the transistors in a Pure Class-A amplifier are never switched off, there is obviously no crossover distortion (there is no crossover – where one transistor turns off, and the other supplies the load current). The amplifier is always fully charged and ready to allow the music flow spontaneously, with a dynamic, fast response time, the music is rich and sweet. Both single-ended (RCA) and balanced inputs (XLR).
Two headphone outputs allow you to share music with your friends.
Luxman holds many patents for audio engineering, amongst them is the application of Global Negative Feedback to the output stage, which while widely used throughout the audio industry, they no longer use themselves.
Luxman nowadays use a distortion reduction circuit called Only Distortion Negative Feedback (ODNF). This system works by isolating noise & distortion at the output from the music signal and sparingly applying negative feedback to suppress them. Conventional negative feedback systems can have an adverse effect on the music, introducing phase distortion. “The circuit features such an ultra-wide range, ultra- high slew rate and ultra low distortion that it does not use phase compensation for the music signal amplifying circuits.” This new technology also ensures that need for a DC servo circuit is alleviated, again improving sound quality.
ODNF revision 3.0 analyses the music signal with three different passes and corrects either noise and/or distortion found in the music signal. The interesting thing is that it only effects that part of the music signal that is corrupt.
There is an input selector on the front panel that allows you to chose between one balanced input (on XLR) or a single-ended input (on RCA).
