Gdhal-
Good that you recognize that the balanced output of the Yggy might be better than the SE. I understand your desire for an apples to apples comparison with the Oppo, but I think an equally valid comparison is "best" to "best". Certainly, if you are keeping the Yggy, you will want the best sound out of it.
Here is where I first heard of the difference:

"2. If you are using the coax (single ended rca's) outputs then you need to take the single ended signal from the xlr connectors for much better sound. There is a summing circuit after the balanced circuits that is not super transparent. This mod eliminates this circuit. You can get or make adapters to use (you use just pins 1 and 2 and you leave 3 unterminated....important!). Another way would be to put xlrs on your cables that use just pins 1 and 2. Another even more transparent way is to hardwired (more on this later). This mod will make the DAC way more transparent and clear.....mucho better."
Enjoy!!
