I have found a used BDA-1 to buy and I have a few questions:
-can the xlr & rca outputs be use at the same time with out any problems(rca for a set of speakers upstairs & xlr for the main system)
-this dac had some software updates last year, what are the updates?
-Serial # 000066, build date 08 34 rev 3, what does this all mean?
