I guess there are a lot of questions that need to be answered first.
Is it used for a stereo system only or for multichannel?
Is it to be used for music or movies?
What will the Oppo be hooked up to?
What formats do you play? DVDA? SACDs? CDs? BDs?
etc
If you are looking for an all in one system that can play BluRays (PureAudio music), SACDs in multi channels, DVDA in multi channels, movies on Bluray and DVDs, it's going to be hard to replace the Oppo.
You can get it upgraded - I'd consider the Modwright tube based output if you can ship your unit across to Dan.
Or for a sideways step, Electrocompaniet and Cambridge Audio use the same Oppo chipsets but have their own analog/DAC stages. I say sideways because they use different chipsets but some may prefer the Oppo's Sabre32 to these versions.
If you are willing to lose 3D and 4K capability, try to see if you can pick up the Ayre DX5. It is based off the Oppo 83 which is still a very capable Bluray player (and SACD/DVDA) but Ayre has a very very good analog stage and DACs that outclasses the Oppo 105, the CA and the Electrocompaniet. Plus it also works like a USB DAC (like the 105's USB input). There is an upgrade for the DX5 that adds DSD over USB (vs PCM only in the original spec).
If you don't care about Bluray playback or DVDA playback, and only play CDs and SACDs, I would look at something from EMM Labs (XDS1 v2) or Playback Designs (MPS5). Both IMHO outperform the 105 - including the modded ones because the custom built DACs are really really quite special.
If you don't care about BD/SACD/DVDA and only care about PC audio or just use CDs, I'd look at the PS Audio Directstream DAC. Just add a PC (or Mac) music server or a CD transport to play CDs.
