What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Luxman L-505 uX

 LUXMAN have launched the lastest generation of transistor integrated power amplifier, the 3rd verison of the highly rated X series, L-505Ux, with a high output power of 100W(8Ω). This high performance amplifier introduces LECUA (Luxman Electronically Controlled Ultimate Attenuator).
Over the last 15 years, since L-505s was first introduced in 1996, it has experienced 3 model changes.
Now the L-505uX, as the latest full revision model of Luxman 506 series, is avidly expected and popularly supported by audiophiles all over the world.

With an illuminated central oriented VU meter on its solid, symmetrical facia, L-505uX introduces a high accuracy electronically controlled attenuator LECUA and Luxman exclusive high sound quality feedback circuit ODNF(Only Distortion Negative Feedback) high S/N version 2.3, while keeping all the other superb features of Luxman products. As an integrated power amplifier, L-505xU inherits all the excellent features of L-590ax/L-550AX, such as ideal circuit design, chassis construction, wiring and layout.
L-505uX mainly features class-leading high sound reproduction capability, high power amplification, incomparable audio performance and the implementation of updated components, making this multi-functional integrated amplifier supreme in bringing to life your love of music.
