if you only need to record a stereo source, the audiophile should work just fine. the audiophile and the entire delta series (44, 66, 1010) all share the same chipset; the difference is the number of channels they can record at once. I have an audiophile and am very pleased with it (quality of sound and support). i think a lot of your choice will boil down to how much you want to spend. As to the isolators... that's out of my league, i'll let someone else answer that one. =) --Andrew On Sun, 22 Aug 2004 16:51:22 +1000 Jason White <jasonjgw@xxxxxxxxxxxxxx> wrote: > My main interest at present is in making archival recordings of > material that I originally recorded on audio cassette.
