The DC-1 was designed to sound very neutral - which may not line up with everyone's needs or preferences. (The DC-1 is also relatively immune to jitter, and to power supply noise, so most "USB tweaks" probably won't have a major effect on how it sounds.)
Agreed, the DC-1 responded MUCH less than the HDP to the USB power supply.
