Description
Sony CDP X777ES CD player. Fully revitalized.
The company was established by Masaru Ibuka and Akio Morita in Tokyo in 1946 as Tokyo Tsushin Kenkyu-jo Research Institute, initialy providing service. A year later, it was transformed into a company called Tokyo Tsushin Kogyo Kabushiki Kaisha (abbreviated Totsuko), whose main purpose was the production of telecommunications equipment and voltmeters. The 50’s turned out to be crucial for the company. At that time, a tape recorder and transistor radio were created, and in 1955 a decision was made to use the SONY logo on Totsuko products. The name came from the Latin word “sonus” – sound and “sonny boy” – used in the US to describe a little boy. The 1960s were a period of rapid development and international expansion for the company. Then also TA-1120 was created, which is the world’s first stereo receiver based on silicon transistors. In 1979, the iconic SONY product appeared on the market, a portable “walkman” cassette player. In the following decades, the company also introduced and promoted trademarks such as discman, trinitron and playstation.
The company’s rapid growth has boosted sales and reputation. In 1960, the decision was made to open the first foreign branches in the USA and Switzerland, making Sony become a true international corporation.
CDP X777ES is the iconic CD Sony player from the early 90s. Similarly to other devices from X7 series, this model is also distinguished by an incredible quality of design, rarely seen in the 90s and today. It has been equipped with a very stable and fast drive, the highly valued KSS-281A laser, as well as the Sony’s original digital-to-analog converter. It is also worth paying attention to its three analog outputs, especially the fixed RCAs that give an even more pleasant, “lush” sound.
It’s no wonder the CDP X777ES sold very well in both Germany and Japan in the 90s, and is now a sought-after legend.
The enclosure has been completely revitalized. Side and top elements have been cleaned and painted using the automotive wet painting technique. Black varnish was used and secured with a clear matte one. High quality finishing screws. The new side boards made of exotic doussie wood give the player an elegant look.
