Since the case is extruded, can't you just use a slightly longer case (like 2" or whatever it takes), and then mount the ODAC board behind the O2 board, thus still keeping both in one case, but providing room to keep the batteries for (semi) portable use?<br /><br />This would also let you put RCA outs on the back and a selector switch/button. I'd like to be able to physically switch the DAC board's output between the amp input, and some external line out like RCAs or a 3.5mm jack. Then I can run that to my stereo, and flip between private and public listening just by flipping the selector.<br /><br />I assume this would cost more, of course, but for me at least this'd be the one-box O2 solution I've been wanting. Would it be possible, and what would it cost?<br /><br />(Also, I note the "desktop" case on the website is like twice as tall as a "normal" case. Does this allow the betteries to be retained, or is the ODAC board still mounted flush in their spot?)
AnonymouseYou could just add a switch along the line out for the public/private listening functionality, though this obviously isn't adding to portability or allowing you to output from the DAC only
