I am trying to achieve a decent quality of sound from iTunes via an external USB DAC. Whilst the current level of performance is OK, it is significantly inferior to that of my iPod Classic 160GB via an Onkyo ND-S1 and the same DAC. I have heard that on Macs, there is the possibility of using software from Channel D - is there a PC equivalent, or any other effective tweak? I don't want to migrate to Foobar, as then all the metadata (track names, artwork etc) are lost, and I have to use iTunes in parallel anyway for the iPod.
System is as follows:
Lenovo T400 / iTunes / standard Belkin USB cable, or IPod Classic 160GB / Onkyo ND-S1 / Swoboda silver digital interconnect, both into Little Dot DAC_1 / AVM interconnects / Little Dot MkIII (stock tubes at present) / Sennheiser HD600s
Sound from the PC is detailed and fast, but lacks bass, body and soundstage in comparison with the iPod. Generally, it sounds "thin".
