Audio Servers

The Digital Audio Server

The Digital Audio Server (DAS) is a true reference designed for the discerning Audiophile. The DAS is one of the finest sounding audio servers available today and will easily outperform significantly more expensive audio servers.

Through the application of proprietary circuit designs, novel circuit configurations and six years of research and development have culminated in the realisation of the reference standard DAS.

The DAS is an extremely versatile audio server with two USB inputs, network capability through a LAN connection and an S/PDIF input. The DAS is primarily an audio server and the best performance will be achieved when files are accessed from a USB pen or HDD.

Alternatively digital audio can be streamed from either a NAS, PC, tablet or smart phone over the LAN connection.

The CAAS DAS has been designed to produce the highest audio quality possible. This has been achieved through the following CAAS Audio proprietary technologies

The Elysian Audio Server

The Elysian Audio Server (EAS) is an extension of the reference standard Digital Audio Server (DAS), machined from a single piece of aluminium, incorporating an integrated Pre-amp with remote volume control, single ended & balanced outputs and additional power supplies with improved isolation.

The EAS is a true reference design which has met our aim to produce an outstanding sounding, unsurpassed audio server and consolidate several very expensive units into one thus bringing true high end performance to a much lower price point.

The EAS is an audio server with an integrated pre-amp and is capable of driving a power amplifier directly, thus replacing up to 4 separate units (e.g. CD transport, DAC, pre-amp, PSUs) and interconnects.

The EAS is an extremely versatile audio server with four USB inputs, network capability through a LAN connection and an S/PDIF input. The EAS is primarily an audio server and the best performance will be achieved when files are accessed from a USB pen or HDD. Alternatively digital audio can be streamed from either a NAS, PC, tablet or smart phone over the LAN connection.

The CAAS EAS has been designed to produce the highest audio quality possible. This has been achieved through the following CAAS Audio proprietary technologies.
