The only thing I am worried about the Apogee is background noise. I remember that the One had a bit of noise. Not sure if that was from the headphone output or...
How black is the background on the ULN-2? Could I use it with GS-1 and JH13 with a perfectly quiet background?
Also, where do you get a pair of decent TRS -> RCA cables? I didn't see any at BJC.
