The MAN301 - the future of high-end audio playback


The MAN301 arguably is the most comprehensive system for music archiving, music library maintenance, music playback, CD ripping, Internet radio streaming and more.

The MAN301 comes in two versions, the "DAC" version includes a D/A Converter, the "SERVER" version has digital outputs only for connecting an external D/A Converter. The SERVER version can be user upgraded to the DAC version at any time.


January 2013: The MAN301 won the "Best of the year award" by

Audiophile / Videophile Magazine, Thailand.


A complete MAN301 system consists of:

  • The MAN301 Base Station as pictured below
  • An external NAS (Network Attached Storage) or DAS (Direct Attached Storage) device, typically a harddisk or an array of harddisks. This allows for virtually unlimited storage space for music files.
  • An iPad device with the Weiss MAN app for remote control of the Base Station.
  • A means of accessing the Internet by the Base Station for fetching CD cover art and CD metadata.

Technical background


The MAN301 uses the Gracenote database for fetching metadata and cover art. While Gracenote is the best database for that purpose, its license costs us a five digit amount every year. We sell MAN301 units to recover the costs, but also offer the possibility to make a donation to us via Paypal for our Gracenote support.
