Audible Illusions Modulus M3 with MM Phono Factory Refurbished with 6 Month Factory Warranty. Audible Illusions only accepts pristine used Preamps for trade to a new M3B or L3A Models.

These factory reconditioned Preamps are very rare to come by and they sell very quickly.
The Preamp is still sealed in its original box, the images of the preamp given are my preamp which is identical, the open top image is from factory.
