In our projects we do not use veneers that are thin, unreliable and, above all, not resistant to damage!
We use only the highest quality veneers,  i.e. wood sheets of 3-5mm thickness. Thanks to this solution and the bonding technology we have developed, our products are equipped with durable and beautiful enclosures.

Description

Sansui QRX 5500 receiver. Fully revitalized. Classic Vintage.

 

Sansui Electric Co., Ltd. was founded in 1947 as a manufacturer of transformers, but already in the 1960s it gained a reputation as a serious producer of audio components. Despite its huge popularity (especially in the United States) in the 60s and 70s, after 1985 the company began to bring much less profits than its rivals (Sony, Pioneer or Technics). It was the end of the heyday of hi-end equipment, which was related to an increase in sales of personal computers. At that time, Sansui Electric Co., Ltd. focused on the production of high-end components in Japan, and also started to produce high quality TV sets and other video equipment, while stopping exports. At the end of the 90s, the brand name was used on video devices manufactured by other companies.

Eventually, Sansui Electric Co., Ltd. as part of Grande Holdings went bankrupt in 2014. It is worth noting that Sansui was the first company to use transformers in audio equipment, and first to introduce to the market a high-voltage tube-transistor (hybrid) amplifier and a QS / RM system (Quadrasonic System / Regular Matrix), which allowed to obtain four-channel sound from two-channel one.

Sansui products already in the 60s were world-famous for their great quality of sound engineering, great design and the highest performance. This was possible mainly because each model was created from start to finish by Sansui experts. Only the best parts were used in production to ensure uniform and highest quality, and each device was repeatedly checked with the most accurate measuring instruments before it reached the customer. Thanks to this approach, Sansui Solid State receivers were characterized by low interference parameters, higher damping factors, greater dynamics, and above all, much better sensitivity and selectivity.

The QRX 5500 is a quadraphonic receiver from the early 70s, its design was based on Sansui’s “uncompromising quality”. In the original catalog, the company recommended this model as “a device for an experienced connoisseur, offering extraordinary versatility thanks to the possibility of connecting 2 pairs of loudspeakers, 3 tape recorders and 2 turntables”.

It is worth noting that this 4-channel receiver was equipped with a newly developed QS Vario-Matrix, a high quality OCL amplifier and the famous QS synthesizer. Thanks to these revolutionary solutions, the QRX 5500 model offers excellent performance, reliability and very high audio fidelity to this day.

The model has been equipped with a new enlarged American walnut enclosure, which brings out its beautiful design characteristic of the 70s. The wood finish is Chinese oil produced from natural oils. Potentiometers are in perfect condition. The device has been fully reviewed and serviced.
