I should be getting it over the next few days, and will be sure to post my findings! For me, even if there is little sonic difference I may still keep the dc-1 for its feature set and smaller footprint.
Also, it's interesting that they told you when you called that the xda-1 and xda-2 sound the same considering the amount of feedback you can find on the internet that says otherwise. When I compared them myself I thought they sounded the same as well, but according to all the feedback I had read prior it seemed like it was going to be a worthy upgrade. Besides even user opinions on various forums, multiple professional review sites claimed the xda-2 sounded better, as did Emotiva reps on their own forum. Maybe they realized with their return policy it would make more sense not to oversell the DAC as they may receive more returned open boxes than they had expected. But thats nothing more than speculation on my end
This is why free trial periods are critically important. I value everybody's inputs to point me in the right direction toward what I want to audition, but in the end I trust no opinion but my own when it comes to my own head-fi system choices... We're buying personal audio, not a concert hall system intended to appeal to hundreds or thousands of people. We don't have to worry about pleasing the "average" listener, whoever that might be. No two people hear/process things exactly the same (except maybe identical twins who have had the same exact life experiences). We all need to try particular head-gear ourselves, not just read others' opinions.
