== Reviews ==
 
* Last top of the line model with medium weight (~12gr) tonearm before the ULM era.
 
* Very flexible in cartridge choice thanks to this and the convenient VTA adjustment option.
 
* Although already equipped with a good V15/III L-M from the factory, the use of much better TAs is worthwhile. As with some other Dual models, the arm has a very good "ratio"
 
with "budget" MMs from Denon (DL30x),Dynavector (DV23/DV17) as well as various top MMs from Audio Technica (e.g. AT20SLa).
 
From today's point of view, the 721 lacks above all a quartz lock of the drive servo control and a housing of equivalent quality to the device.
 
 
 
 
 
* The above mentioned prices are probably former list prices, because already in the Hifi Yearbook 9 the 721 with V15 is listed with 728 DM.
 
* At the beginning of the eighties the 721s from the newer production (the ones with pick plate) were sold for ~ 500 DM and were sold off in piles as discontinued models.
 
Meanwhile the 721 tends to 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.
