What he means by resampling your audio signal, IIRC, is the fact that some amplifiers, especially digital ones, could be actually copying and breaking down analog signals before they make it to the speakers or other outputs/inputs for recording. It's kinda like what a CD player does when converting the digital information into analog sound when connected via the old school RCA cable.
As far as the "noise"....
You know, the more I think about it, the more I think that I was being too harsh and expecting way too much from an old (but loved) format. As I said before, it wasn't necessarily audible, but it showed on my level meters on the computer. I just think the meters in the software are set for pure digital sources, so the "noise" seems to be more pronounced. I am going to get the kit again, do a few things differently, and get the job done the way I want to do it. I honestly think the next time I get into it, the results will be worth it.
Of course, I still welcome any input from folks out there that are into this kind of thing. :)
