This is argually the best Direct Drive Turntable ever made. It's the monumental Denon DP100M.
It cost about 900,000 JPY in the early 80s - a LOT of money back then and would equal about or over 30,000 Euros today!!
Very few were produced, probably under 200 pieces and only on incomming order basis.
This TT is a massive player weighing in at 63 kgs with the wood base/housing and about 48kgs without.
The motor is identical to the ones used in the Record cutting Lathes also made by . . . you guessed it - Denon! An extremely strong, quiet and hyperexact drive.
Has the Denon specaility: Double Split Platter construction - essentially 2 platters in one where the inner one is suspended by springs to isolate from resonances.
The whole massive cast metal base is suspended in heavy duty springs and viscous dampers. The wood housing is removable.
The M stands for the complete player with arm. The arm is a very well built and extremely stable variant of the Denon speciality: the Servo Tracer. It actively dampens out resonances both in the vertical and the horisontal plane.
The player is perhaps more common (!) without arm and is then called DP100. The buyer could then mount a suitable arm of choice on it.
