If you want your computer audio to move several steps up the upgrade path, then the hiFace Evo USB to S/PDIF Bridge Adpater should be on your shopping list in conjunction with a top notch DAC. With the hiFACE Evo, you can convert the digital signal that is fed via USB through your computer out in 24 Bit/ 192KHz prior to it entering the DAC. In most application, the sound difference is quite noticeable, with better detail retrieval and better sonics. M2Tech offers an external power supply option which will probably improve its performance further but we have yet to try that and only have its supplied wall wart power supply. Pls see pics for the many input and output options.
Cosmetically, the unit is in good shape. We have the original box for it and will securely pack it for safe shipping.
