Acoustical Systems Astellar Turntable

The complete info about the Acoustical Systems Astellar Turntable. Acoustical Systems writes: The ultimate turntable. Reduced to the absolute maximum performance. The essence of 33 years turntable design and evolution in the APOLYT finds it’s cumulation in an all-new turntable concept. The task was to transfer the relevant and unique design features of the extremely large and heavy APOLYT into a considerably more compact and feasible format – without losing even the tiniest aspect of the all-alone sonic level provided.

All the design features and inventions which defined the unique apogee level of the APOLYT’s sonic performance have now been incorporated in a much more compact and positively matured new design.
The ASTELLAR is literally the design result of “the road of excess leading to the palace of wisdom.”
A turntable second to no other – in its concept and sonic performance on a par with the APOLYT and superior to all others.


  • A unique 36 (thirty-six !) layers design platter, incorporating 18 different materials with defined energy transfer speed – combined in the optimum sequence.
  • Incorporating Vinyl, Tungsten HD18, Titanium, AW6082 Alloy, 1.4401 Vanadium Steel – plus a defined mixture of organic material layers pressed together and bounded by natural resin.
  • Featuring the unique APOLYT-concept inner platter design – and going beyond that.
  • The ASTELLAR’s platter is 100% non-resonant, with a truly unique design concept featuring an absolute non- reflecting inner surface.
  • Designed to provide the utmost possible pitch-black deep dark “sonic background” – to allow the most tiny details to appear in an unforced and natural way and thus to integrate swift into the all-harmonic sonic picture provided.
  • The platter spindle is fully decoupled and isolated from the bearing and featuring an inner thread to allow optimized coupling of vinyl record to material-identical platter surface by screw-on clamp as well as any record weight.
  • A bi-radial, unique adjustable push-pull magnetic bearing, completely
  • maintenance-free – proving a perfect isolated and totally vibration-free rotation.
  • Full air suspended plinth with 1.2 Hz resonance frequency.
  • True 3-point precision leveling with tilt-prevention.
  • Plinth featuring 3 levels made from 3 different Aluminium alloys –
  • with inlays of Titanium and vibration-absorbing gel.
  • Tonearm mounting boards with “Zero-tolerance” –
  • automatic perfect re-location design:each tonearm mounted and aligned on one position can be moved to any of the
  • ther 3 positions without ANY re-alignment / recalibration needed.
  • Arm boards with defined and maximized energy transfer.
  • Double-point brushless DC motor belt drive – with active dynamic control motor
  • management – and free of any parasitic side force / drag applied to the platter.
  • Double flywheel drive – with maximized inertia incorporated in the active
  • motor management.
  • Totally decoupled bearing level and tonearm mounting board level from
  • motor level.
  • Speed 33, 45 and 78 – all full stabilized with below 0.01 derivation from
  • set speed.
