Luxman L 58A Amplifier. Classic Vintage. Premium version. Fully revitalized.
Kinsuido started in Osaka in 1925 as a producer of photo frames. Its second president initiated the LUX brand that created radio receivers. Kinsuido published a book that was advertised with the slogan “Reading it once makes you an expert in the field of radio.” This item has proved to be a bestseller, has 14 editions and to this day continues to shape the minds of sound engineers. In addition, Kinsuido was the first company in Japan to display and sell radios in stores. Many people stopped just to listen to the beauty of the sound. At that time, Japanese listeners were addicted to the technology coming from the United States and Europe. Import of radio equipment and parts was a long-term undertaking for Lux Corporation. Later, the company decided that to successfully compete as a supplier and reduce import costs, it also had to produce parts on its own. This triggered the creation of the Luxman brand. At the turn of the 70s and 80s, Luxman gained worldwide renown thanks to the quality of sound produced by its equipment, and above all its tube amplifiers. In 1984, the company was taken over by the Japanese brand Alpine Electronics. The decision to include the prestigious Luxman brand in the market war with commercial Yamaha almost led to its collapse. Alpine sold the brand in 1994 and since then Luxman Corporation could again focus on its main goal, i.e. creating the best audiophile equipment in the world. In 2009, Luxman Corporation was acquired by International Audio Group Ltd. IAG and to this day is one of the oldest manufacturers of electronic components in Japan, which is reflected in the slogan of Ultimate Fidelity since 1925.
The LUXMAN L-58A is an exceptional integrated amplifier produced in 1979, during the “golden age” of Japanese audio equipment. This model is equipped with the famous, groundbreaking Duo Beta Circuit, which enhances sound quality and minimizes distortion. The power amplifier section, based on MOS FET transistors, guarantees 100W of power per channel at 8 Ohms, with a minimal harmonic distortion level as low as 0.015%. The L-58A model is extremely convenient and efficient, thanks to the option of separating the preamplifier and power amplifier, a two-position bass boost, and high-frequency and subsonic filters. It also features tape copying and monitoring in both directions, a tone bypass function, and the characteristic Luxman touch mute button. The high-quality components ensure exceptional durability. This is an excellent choice for demanding users who appreciate both aesthetics and superior sound quality.
The enclosure has been completely revitalized, made of teak wood. The wood finish is Chinese oil produced from natural oils and natural turpentine-based beeswax. All external metal elements have been cleaned and painted using the automotive wet painting technique. The device has been fully reviewed and serviced. The amplifier has been equipped with new aluminum feet.
