I couldn't hear any difference in dacs up to $2500, through perfectly respectable speakers, electronics and cables. I tried, it just didn't happen. So I'm not the least bit surprised that you're not hearing it either between the Oppo and Schiit. Might things "change" over the next month or so, sure, but you'll never know if it's the placebo effect and your mind trying to justify the expenditure. So you have two choices - if the money means nothing and you really love just collecting gear, keep both. I own 4 sets of speakers, so you wouldn't be alone there. Or, if you can find something better to do with the $2K - home improvements, weekend getaway, funding a philanthropic endeavor, whatever - return the Schiit and find yourself holding $2K you'd already mentally said goodbye to and do something else with the money. But it's a safe bet that if you haven't already had your "wow" moment, it's not going to happen.
