So you are telling me that I can just go out to the A5's via a 1/4" stereo to RCA interconnect without affecting sound quality ??? |
I can tell you that I'm usiing a decent gold-end cable that comes out of the UD-10 with a right angled mini stereo phono plug and goes into my amp with two RCAs and it sounds great. Seems a bit clearer and brighter than whatever is built into my Mac laptop. I don't know how it would compare to Foobar.
The difference I hear may not be the DAC, but the lack of coloration in the UD-10's output: I don't believe there is any kind of "headphone" amp behind the headphone jack on the UD-10; it is just whatever is built into it to step the output up to line level. That's a good thing in the sense that there is no extra circuitry there to introduce extra noise. Also, the UD-10 is designed and built to be transparent (it is a transport and understands its purpose), so there is probably no warmth added at the output stage of the DAC as there is in so many of them. That's fine with me, my amp and cans are warm enough, I don't need my source colored.
I haven't tried the mini phono to RCA adapter that comes with the UD-10 in conjunction with standard RCA cables, but I don't imagine it would make an audible difference. I already had the cable and it was a cleaner, simpler solution, so I used it.
If you have any use for the other outputs of the UD-10, it's a good buy. Otherwise the SuperPro seems like it might be a better deal.
At some point I may use its transport capability to test different DACs, but frankly, I think it is doing the job quite competently as is. Consider the source, though. I'm of the belief that the point of diminishing returns is pretty low when it comes to components, and I believe that DACs have a simple job to do and should do it without any fuss or added "tone." Simpler is better, from my POV. Expensive generally equals a lot of features and connections I don't need, and very expensive generally means a DAC that is changing the character of the signal (making it "warmer") at the source. Bad joo joo.
There's a lot of different mileage out there, though.
