Superb digital interface
This digital interface is an excellent sounding unit. it takes several hours of break-in period but the result is Amazing, paired with THE CORRECT power cable (pay attention with this!)

It is very well built and the overall feeling is from a high quality finisth standard. For the price, nothing to compain about.

Plugged to a trusty Belden 19364 cable with iego gold plugs, the performance is shifted to stellar results,

a very worthy purchase!
