Send the DSD Signal from SACDs and PCM from Blu-rays/DVDs to an Outboard DAC:  GeerFab Audio D.BOB Digital BreakOut Box Unlocks the Potential of Your Discs

Freedom: The blue-ocean GeerFab Audio D.BOB Digital BreakOut Box extracts the DSD signal from your SACDs and high-res PCM data from your Blu-ray, DVD-A, DAD, or DVD discs so it can be sent to your outboard DAC. While the Stereophile Class A Recommended D.BOB only has an HDMI input, meaning you will need a universal player with an HDMI output to use it, never before have music lovers and cinephiles had such an opportunity to hear so much from their previously locked-down physical media. You won't believe the sound quality that has been buried in your collection of SACDs, Blu-rays, and DVD-based discs. We're talking staggering improvements in clarity, dynamics, focus, presence, definition, soundstaging, and more. Practically any audiophile trait you can imagine gets elevated with D.BOB in the chain. You need to experience it for yourself, and with a risk-free in-home audition, you can.

From a technical perspective, D.BOB is a breeze to use. It outputs DSD64 via the DoP protocol and PCM up to 24-bit/192Hz through S/PDIF coax (and up to 24-bit/176kHz through S/PDIF Toslink outputs) to your external DAC. What's more, D.BOB is fully HDCP and copy-protection compliant, and comes with a mini-USB port for firmware updates. Its HDMI pass-through allows for player menu settings and other video uses.

We all know the performance of built-in DACs on years-old universal players is very dated. D.BOB ends the limitations and opens up what's really embedded on your discs. 100% Music Direct Guaranteed.

Disc-player compatibility note: D.BOB only works with universal disc players with an HDMI output. D.BOB only accepts HDMI signals.

DAC compatibility note: D.BOB works with most DACs. For DSD, the DAC must accept DoP via S/PDIF Coax and/or Toslink.

"Many [readers] will pounce, knowing that the D.BOB can assure continued access, into the indefinite future, to the SACDs in their collection via the DAC of their choice. You know which group you're in."
– Kalman Rubinson, Stereophile

"The D.BOB fills a void that desperately needed filling. It not only simplifies source selection when playing higher-resolution discs, but also delivers consistently high-quality audio when attached to a current-generation DAC or DAC/preamplifier."
– Steven Stone, The Absolute Sound

“If you still love your SACDs and to a lesser extent, Blu-ray Audio DVDs, and are not interested in making a five-figure investment in playback, the D.BOB is truly the way to roll.”
– Jeff Dorgay, TONEAudio

"For many old school audiophiles (like myself) who prefer curating their own music collection and listening with album notes in hand, the improvement in sound quality the D.BOB provides is rationale enough: why rely on the player's outmoded DAC?"
– Brian Kinch, Positive Feedback

"It not only simplifies source selection when playing higher-resolution discs, but also delivers consistently high-quality audio when attached to a current-generation DAC or DAC/preamplifier."
