.....and now for something completely different. I own a Proceed PDT3/PDP3 combo. I don't have a lot of experience with seperates, but heard that a jitter reduction device was a plus. I found a SF UJB for $125 used, so I figured, what the hell? I actually liked what it did. I thought it increased extension and detail, especially in the bass region. I also thought the overall sound was 'smoother'. My question to you other gentlemen repliers is: What in/outs did you use? I've only used balanced in's/out's. I don't know if this might explain the difference or not. I'm using it now, happily I might add, as you can tell by my equipment, I can't afford to keep up with the latest technology. I tend to be more a fan of classic equipment. I'll be interested to see the replies, could be a synergestic thingamabob.
