so there seems to be a couple UA-5 questions out there so I'll throw my pretty pointless (and possibly easily researchable) ones into the ring:
First, what kind of output power does it provide without the 48v switch on? I assume it has to give something as otherwise it'd just be an ADC right? I ask mainly because this is exactly how I used it tonight. I assumed it provided some kind of power (I don't know anything about how pres work mind you) but with the 48v button off it wouldn't provide a signal from my CA-14s (yes its weird, shut up).
Second; would a mod (in this instance an Oade Pmod) effect how the D/A conversion worked or sounded? I ran CA-14 > 9100 > UA5 > H120 (optical) and while its rather unorthodox it sounds fantastic, best pull I've gotten from the particular venue.
