Quadral Aurum C9 Reference CD player


Quadral AURUM C9 – Made in Germany (Special Order Only)



Due to its uncompromising architecture, our AURUM C9 reference CD player provides the bits & bytes of a CD to reach their true potential totally unclouded. An undocked drive surrounded with sophisticated vibration dampers is just one of many technical highlights helping to make this a true reference class player.

As true a reproduction to you actually being there when originally recording or performing is another testimony to the abilities of the C9 player.
