I run AKG's and Oktava SD mics into a UA-5 and then into my R-09 via the RCA outs. Works great and I am very happy with the sound and setup. Yes, there is an extra A-D conversion in there, but honestly, I can't hear the difference and others have said they are also very satisfied despite the extra A-D conversion in the signal path. Unless I upgrade my recorder, this is what I'll be running.
