Avarice
De-jittering and up-sampling unit.
It is no secret that considerable differences can be heard between the sound of various sources of digital signal (digital transports), connected to the same DAC.
These differences may be quite large, even though the source digital data remains the same. What is the cause of these differences? The answer is not altogether straightforward, the causes can be found in the instability of the clock signal, signal interference, earth loops etc.
The Avarice is a stand-alone device that is able to perfectly galvanically isolate the signal source from the DAC, significantly suppress any instabilities in the clock signal, and also to improve the CD signal by up to 4 times up-sampling. You would be surprised to discover how signal sources that had been un-listenable previously - such as cheap DVD players, PC sound-cards, media streaming devices or satellite receivers - can play sound as top-class digital transports, when combined with the Avarice.
