This interesting tidbit from Naks.com <http://naks.com/>:
“The DRAGON’s unique double direct drive system employs two Nakamichi quartz PLL servo Super Linear Torque DD motors one for each capstan so that wow & flutter are essentially eliminated while maintaining perfect transport stability in both forward and reverse directions."

The machine only records in forward, but plays back due to it's six-track play head--the right channel of each side is actually two heads as explained above, in order to do auto azimuth. It works reasonably well on high-quality material and nothing sounds as good IMHO. I have seven.
