About GeerFab Audio: A division of GeerFab LLC, founded in 2006 in Milwaukee, WI as GeerFab Acoustics, a leading developer and manufacturer of acoustic products for recording, broadcast, live performance, restaurants, hospitals, museums and education. GeerFab Audio was founded in 2017, with the D.BOB being the first of a good handful of products designed to release hi-res discs of all kinds from the tyranny of internal DACs-in-the-box.

The D.BOB has arrived and is currently available at:

A. Universal player must output DSD64 and up to 24/192 PCM via HDMI. If there is only one HDMI output, use the HDMI OOUT on the D.BOB to send video to a monitor or TV.

B. External DAC must accept DSD via the DoP protocol through S/PDIF Coax (preferable) or Toslink inputs. The D.BOB does not have a USB output.


Each individual GeerFab Audio D.BOB undergoes comprehensive quality control and a complete test before shipping. This D.BOB is warranted by GeerFab Audio to the original purchaser against defects in workmanship and materials used in manufacture for a period of three (3) years from the date of purchase. Faults due to customer misuse, unauthorized modifications or accidents are not covered by this warranty. No other warranty is expressed or implied.

If you suspect that your product is faulty, please contact the retailer from which you purchased the unit and the retailer will contact GeerFab Audio. Sometimes a defect is simply a transport or DAC not properly setup or a DAC that does not support DoP via S/PDIF Coax (see System Requirements below). If a purchaser wishes to return a unit because of system incompatibility, it is at the retailer’s discretion to accept a return or exchange. GeerFab Audio is not responsible for customer's system incompatibility.

Prior to shipping, customer or retailer must obtain an RMA number from GeerFab Audio for warranty services. Units sent without RMA number will not be accepted. GeerFab Audio will repair or replace a defective unit with a new or refurbished unit at its sole discretion. The warranty from the original unit will stay in effect through the original term.
