Differential D/A Converters
The CD-S1000 uses high-grade differential D/A converters for the left and right channels, with their output assigned separately for plus and minus. Developed by drawing on Yamaha’s long experience in digital technology, they ensure the highest conversion precision, as well as outstanding S/N ratio and dynamic range. All other components, including the analogue circuitry, were carefully selected based on extensive listening tests. Comprehensive sound tuning, encompassing even the mechanisms, means that you will enjoy incredibly dynamic and powerful CD reproduction.
Exclusive Yamaha Loading Mechanism with Superior Quietness and High Precision CD Drive
The mechanism that picks up the signal is actually analogue, even during the digital reproduction of a CD. So its degree of precision has a surprisingly large effect on the reproduction of the digital signals and the final sound. The CD-S1000 features the Exclusive Yamaha Loading Mechanism with Superior Quietness, which uses Synchro-Mesh rather than noise-producing gears, for totally silent tray movement as well as extremely high durability. The rest of the mechanism is also top quality, including a highly reliable brushless spindle motor and a diecast aluminium tray that is completely free of vibration. The thick steel and wood chassis is very heavy and stable, far superior to ordinary types made partly of plastic.
Four-Part Power Supply with Independent Structure
The power supply has four sections – for the audio circuitry, the digital circuitry, the drive mechanism, and the display – which are physically separated from each other and from the transformer, minimising both mutual interference that degrades sound quality and the effect on earth electric potential. The power supply for the audio circuitry is a constant current type with an independent left-right structure; it ensures a stable supply of clean power and contributes to superior channel separation.
The CD-S1000 provides the Pure Direct circuit that is a popular feature of Yamaha amplifiers and receivers. Since it has separate analogue and digital sections, the same as a good amplifier, the designers decided to make use of Yamaha’s amplifier technology to help achieve high sound quality. When Pure Direct is on, the display is turned off and digital output shuts down, providing the highest possible analogue sound quality.
