【List Price ¥107,800】LUXMAN T-300X FM Tuner Luxman

LUXMAN T-300X

This is LUXMAN's high-end FM-only tuner, originally priced at ¥107,800.
While it may be difficult to convey through photos, the actual unit has a design that exudes LUXMAN's characteristic luxury and dignity.
As expected from LUXMAN, it offers a unique experience.

It features a unique Accu-Touch Mechanism system. When tuned in, a red indicator lights up, and the dial locks with a satisfying click, like a magnet, achieving perfect tuning and providing a truly pleasant sensation. (This mechanism is likely one-of-a-kind worldwide.)
Significant cost has been invested in the power supply, which is the foundation of audio equipment. Despite its slim profile, it is surprisingly heavy at 7kg.

Basic operation has been confirmed.
Overall, it is in beautiful condition, but as a used item, there are minor scratches.

It employs a unique C.L.L. (Closed Loop Locked System) for tuning.
This system uses the crystal-controlled transmission frequency of FM stations as a reference to control the entire tuner, including the front end, IF (Intermediate Frequency) stage, and detector stage. This ensures stable reception unaffected by external conditions such as temperature fluctuations.

To further enhance tuning accuracy, the capture range of the C.L.L. circuit is set to a narrow band.
In this configuration, traditional tuning methods relying on the center meter become difficult. Therefore, the T-300X utilizes the control voltage from the C.L.L. circuit to detect the precise center point, and the Accu-Touch Mechanism engages a mechanical lock based on this detection.

The front end features a 5-gang variable capacitor exclusively for FM, enhancing the selectivity of each high-frequency amplification circuit and ensuring sufficient interference rejection capability.
The IF stage offers bandwidth switching. In the wide position, two sets of LC block filters with excellent group delay characteristics achieve ultra-low distortion. In the narrow position, an additional narrow-band ceramic filter is added to achieve high selectivity.
Furthermore, the quadrature wideband detector circuit is designed for low distortion, contributing to a high signal-to-noise ratio.

The MPX circuit is equipped with a pilot signal canceller circuit.
The audio stage employs a DC amplifier configuration.
