The DEMO Sony SCD-CE595 is a 5-disc CD player offering playback of both Super Audio CD's, recorded in DSD format, and standard audio CD's. DSD (Direct Stream Digital) recordings use sampling frequencies (with 1-bit quantization) that are 64 times higher than the Red Book audio 44.1 KHz CD sampling rate. The result is a much wider range of dynamic and frequency reproduction, and greater fidelity to the original sound.
The SCD-CE595, mounted with a DDLOP (Discrete Dual Laser Optical Pickup) setup, reads both single layer SACD-only discs, and Hybrid dual layer SACD discs which provide an additional CD layer as well. SACD layers support both 2-channel stereo playback, and multi-channel playback up to 5.1 surround. the areas are accessed via a front panel selector button. The CD layer on a Hybrid SACD will play back on conventional CD players. The advanced servo mechanism in the unit allows for significantly improved track access and selection.
This player is very affordable, and offers the consumer an alternative technology and recording format that bridges the DVD and CD mediums and expands the possibilities of digital sound reproduction.
