I'm looking for a mini-disc deck to mix down to. There are a number of used Sony MDS JE510s and 520s out there. I was under the impression that if the deck has digital out, that I could go to CD with an exact duplicate of my master, is this correct? Last night I read somewhere, on one of the unit reviews, I think, that the guy said he wished he could have stayed in the digital domain and he was talking about going from minidisc to CD with some pre-recorded music. I am recording on a yamaha MD8, so I know I will be going into the mixdown deck through the analog jacks, after going through this, and 2 rounds of data compression, I would certainly like to go to CD with an exact duplicate of my master. Also, do all of these decks use 4th generation ATRAC. I know the later models do but is there a year that it started and everything before that used a lesser version? Is anyone else mixing down to minidisc, and what are the things I should look for when buying a deck?
