Long story short, Got a e10, had problems. Got a Udac-2 to compare if the problem was my DAC or computer. Turns out it was the DAC that was the problem. Now that I've spent 110 on the Udac-2 I decided to compare it to the e17 that's only 20 more.
So..in terms of DAC which is better? the Udac2 or the e17, I have no need for an amp at the moment.
