I owned a NAD 6300 a long time ago. Superb sounding machine that was very well put together. As far as I know this is the only three head deck that NAD ever made. If you can find one used in good condition for a reasonable price, buy it. I owned top of the line Denon, Teac, Sony ES, and Pioneer Elite, models and the NAD was easily the best sounding tape deck I ever owned.
