I wonder, has anyone tried this before? What would I need to do in order to make a preamp (say the db680) power a pair of headphones? I'm sure the preamp out has more than enough power to drive a pair of cans, so should I just get a 1/4" male to female and somehow split the mono signal into both L and R channels? I ask because Aguilar didn't add a heaphone out... And that seems strange to me. The other alternative is just to run the preamp into my computer and then listen on the heaphone out of that. But I'd like to keep path as simple as possible. Thanks!
