I have a 788 also and was thinking of upgrading, but i dont want to risk damaging the unit.
Joe, i have started to put my 788 mastered cd's in my pc and I have used music match to convert to wav, although i am sure there are other programs of course
Also I picked up a cheap $10 copy of magix's music studio at comp usa. It allows one to add 10 band eq, compression, normalization, and reverb/delay to wav files.
They have a more comprehensive edition for $40.
I was going to upgrade, but figured i would just spend the money on a ton of 650mb cd-r's for backing up, since I am using on of the Teac cd writers that does not accept the 700 mb discs.
I am hoping tascam introduces a new recorder (788 is almost 3 years old) that would have a larger hard drive and built in cd-r similar to Korgs d series
