I had the same issue with my 105. Strongly suggest you NOT modify it, but find the right DAC. It is not hard to outperform the DAC in the 105. I use an LKS that beats the 105 by a mile, but it’s not for everyone. If you decide to sell a modded 105, you will never recover anything like the cost. If you buy a good DAC it will give you many more options as your digital universe opens. I’ve moved way past the 105 using it now for video and for ripping SACDs.
As for which DAC, that is such an open question that there is no right answer for everyone and every system. You'll have to do your homework. Two people will compare two DACs on different systems. One will hear no difference; the other will hear a great difference.
I don’t know why folks on this board are so resistant, but the best SQ (as well as ease of playing) is gotten by getting rid of "players" and ripping silver disks.and sending the files directly to the DACs. The silver disks add nothing, only detract.
