https://youtu.be/Wm05aM7OGw8?si=Q6jVDCu5cdvBn83D ST-S770ES Tuner was the top of the company’s premium ES range (above the 500 and 300 series), with exceptional build quality and thoroughbred engineering in a large (430x95x372mm, 5.8kg) container. The ST-770ES, for example, despite the fact that the RDS (Radio Data System) had been around for a few years, did not have it installed, but the cheaper tuners in the range did. Why? Because Sony’s engineers couldn’t get the unit to sound as well as they desired with an RDS chip inside, they decided to remove it. In other words, it was built to prioritize sound quality over all else – but, because it was made in Japan, it didn’t mean it was devoid of the majority of the frills expected of a premium tuner. Item is in excellent, but used condition. Everything works as it should. This is one of the best tuners and was over engineered by Sony when they were top of their game in 1991/1992. You will not find a better tuner for the price. These items sell for over 400 GBP in Europe.
