I am interested in buying a BDA 2 to be used solely as a DAC connected to my CD player using a coax connection. No computer, downloads, hires etc.
Strictly using CDs that I own. Do I really need to update the firmware ( if a newer version is available ?) I am concerned that I could screw up the process and would only do it if there is some significant advantage given the way I'm using the DAC.
I own a BDA-2 as well and as far as I know, upgrading the firmware is pretty useless and potentially hazardous. It is my guess that the revised F/W was to complement the newer revisions of PCBs inside, not to add features or change the manner in which the DAC behaves.
So, if your BDA-2 came with a specific F/W, then I would leave it as it is.
In fact, now that we're talking about it, I would have liked to see the BDA-2 muting the output before the UP-SAMPLE is engaged as it sometimes produces a loud click through the speakers. That would have been one F/W revision I would have liked to see. But I doubt it will happen now that BDA-2 is on it's way out, or has already been discontinued.
Hope this helps!
