I run the UD-H01 along with the Squezebox touch on a small Rotel chain. The sound of the Squeezebox is thus really good revalued. About USB in the PC listens to also super and is a real recommendation as an external sound card. Sonically, tactile and functional actually five stars. A deduction there was to operate the TV. Because every time you switch the frequency / clock .... (HZ) is recalculated every time you hear the click of the relay (or the like ...). Anyway, quite annoying and determined in the long run not healthy. For zapping totally unsuitable. A remote control and one or two additional inputs would not be bad. Apart from this limitation, a top unit.
