Dragon, because the Dragon adjusts the azimuth for each tape, which maximizes the potential quality of playback; it literally cannot be any better. It is not an acacemic question, like "best typewriter". I have several thousand cassettes, many incredible bootlegs, masters I made myself. The clarity of a master tape exceeds anything commercially available in certain ways. It sounds "alive" in ways no studio or commerial release possibly can. Note, however, that the deck you made a tape on may be the best playback deck for that tape. - the azimuth will automatically be correct, unless it has changed for some reason. Note also that the eq curve for Naks was non-standard. Note also that the eq curve for Naks was non-standard, so there can be compatibility issues if the tape was made on a different deck. That said, I want a Tandberg 3014, because the are said to be more reliable that the complexity of a Dragon - occasional visits to the shop are to be expected.
