SW1X Audio Design™ CDP III

Performance Level 3

Complete DAC Player & Streamer

CDP III = DAC III + VDT I/2 Transport & Streamer

CDP is short for Complete DAC Player. Similar to a CD Player, CDP is a Single-Ended (SE) version of a SW1X DAC with a VDT Digital Player/Streamer housed in one chassis.

This is a harmonically matched solution for those who are looking to maximise the musical and analogue characteristics of SW1X digital source without the hassle of mismatch stemming from multiple chassis products.

Everything is designed to be UPnP & DLNA ready- just connect & discover the device on your network & control the playback of your music media via touch screen or another device.

SW1X Audio Design audio products were designed for maximum performance and also to ensure compatibility with majority of audio systems. However, for maximum musical pleasure, we recommend to pair our products only with our harmonically matched system components. In order to achieve best possible results, the matching system component should ideally be on the equal performance level or alternatively within one level below or above.

Note: Due to SW1X Audio Design's ongoing research and development process, specifications are subject to change without notice
