If it were me, I'd keep the 105, but send it to Ric Schultz at EVS. He has an extensive mod program for the 103 and 105. Roughly $2,500 to mod your 105 into an unbalanced, 2-channel player, but you can also get the balanced mods and/or multi-channel mods at additional cost. I have his modded 103 and it's fantastic - light years ahead in sound compared to stock - not even remotely close. Ric recommends the modded 103 for use mainly as a transport and the 105 if you want a world class CDP. Ric tells me his 105 is the best digital playback out there and I'm not inclined to doubt it! Modding does void the Oppo warranty, but he guarantees his own work for life or will repair a non-EVS fault for the cost of parts and $25/hr labor. Or he will sell you his own 2-year, complete warranty for $50. Just Google "EVS Tweak" and that should get you to his site. I've found Ric to be very easy to get to know by phone and he does great work. (EVS = Electronic Visionary Systems)
