  • Excerpt from User manual: Dual CS-721 in walnut
  • Last top model with medium-weight (~ 12gr) tonearm before the ULM era.
  • Thanks to this and the convenient VTA adjustment option, very flexible in the selection of pickups.
  • Although already equipped with a good V15 /III L-M from the factory, it is worth using much better TAs. As with some other dual models, the arm has a very good "ratio"
  • From today's point of view, the 721 lacks above all a quartz locking of the drive servo control and a housing equivalent to the device in quality.
  • The above prices are probably former list prices, because already in the Hifi Yearbook 9 the 721 is numbered with V15 with 728 DM.
  • At the beginning of the eighties, the 721s from the newer production (those with pimple plates) went away for ~ 500 DM and were sold off in batches as discontinued models.
  • Meanwhile, the 721 tends to have lover prices in the used market.
  • Unlike many Japanese direct drives, the servo control of the motor is not based on a special PLL chip, which is now Unobtanium.
