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 D-103u CD Player


High-Quality Vacuum Tube Analog Output Stage
The D-103u was designed to make the unique design of the D-105u available to more conservative budgets - without compromising on sound quality. That means using the same basic components in the analog signal path: two triode vacuum tubes in the output stage to recreate the delicate, transparent tones of the original performance.
Advanced Digital Output Stage
The D-103u also offers 18-bit , 8-times oversampling digital filters, and independent dual D/A converters. The STAR Circuit helps preserve signal purity at all stages.
"Mid-Ship" Mechanism
The ideally balanced, central position of the disc tray combines with Luxman's High-Rigid Lock mechanism to enhance the anti-resonance of the D-103u
Features Emphasize Ease of Use
Convenient D-103u features include: remote volume control, switchable front panel display dimmer, vacuum-tube warm-up switch, and 32-track random access and track programming.  In sum, the D-103u offers everything that a music lover could ask for  - and more.
