Ok here's the deal. As an experiment I am contemplating on buying a two track reel-to-reel system, to enhance the mastering of a 2 track mix. I keep seeing most of these units on craigzlist that are typically Tascam or some other decent brand (2-4) track reels, ranging in price from $500-800. Now can any of these models help mastering for a lo-fi home production? I don't need the greatest reel to reel , but I want to know if a semi-cheap model is gonna help any? I mean to ask as well if this is a common step in mastering digital recordings these days? Will I benefit at all by transferring digital mixed recordings to analog tape and then back again digital? So if this idea is really bad then let me know. I mean to say that I understand that my DA/AD converters are really important, and the hiss of a tape machine can be deadly. Will I need to get Dolby noise reduction devices as well? Or can I use digital software NR to achieve a similar effect after bouncing from tape to digital? Assuming that DolbyNR is necessary, how much is a good unit used price? This might just be a big pain in the butt really, or it might be the start of something great. I've heard ppl say they like bouncing a 2-track digital mix track to analog. Or at least have it around to record things. Any advice that anyone has would be greatly appreciated.
