I advocate keeping the 6.5X gain - it comes in handy when using 1V (or less) sources and HDR recordings (Live music, Movies, some Video Games). Particularly if you are using the O2 with headphones in the 90 dB efficiency range. If you think that will NEVER be the case, unity and 2.5x will probably be great.
Remember that if you wanted, you can use the windows volume control (for example), you get your levels where you want them with whatever phones you are using. Also, you can take the O2 from 2.5X to 6.5X to 1X, 2.5X if you want, but you can't "add" gain later!
Hmm, I am getting the ODAC+O2 combo so my source will always be the same. Either that or I'm misunderstanding you.
