The GeerFab Audio Digital BreakOut Box (D.BOB) extracts DSD64 and up to 24-bit/192kHz PCM from discs to an external digital audio converter. Unlock the DSD64 and hi-res PCM from your SACDs and Blu-ray Audio discs, then output the data stream to an external DAC for D/A conversion with full HD copy protection.
"I loaded the Oppo [UDP-105 universal player] with a recent SACD of pianist Romain Nosbaum playing a selection of 'Saudades' by Spanish and Latin-American composers (SACD, ARS 38 287). It's a delightful hour of charming, witty music, played with panache and nicely recorded. I had been enjoying this recording in multichannel via a ripped file on my server; played in stereo direct from disc, via the D.BOB and my Mytek Brooklyn DAC, it lost a little ambiance (relative to multichannel) and gained a little focus. When I compared the stereo DSD file with the D.BOB disc playback, there was little to choose between. With more complex music, such as the spritely and elegant Sextet Op.142 by Ferdinand Ries, performed by the Franz Ensemble (SACD, MDG 903 2136-6), the stereo-file-to-D.BOB comparison was still a draw.
I also made comparisons between the GeerFab S/PDIF output and the direct connection from the Oppo to the Brooklyn with the same recordings, but since the Oppo (like other players) does not support DSD via its S/PDIF output, I was comparing the DSD tracks with the Redbook CD tracks. Even so, the differences were small once the levels were matched. I consistently felt that DSD via the GeerFab had more generous ambience and smoother treble. That's a sighted comparison leading to a subtle, subjective distinction, so I prefer the conclusion that DSD via the GeerFab was at least as good as direct CD playback and probably better.
With this box in your system, you'll probably also be using it to play audio from your CDs, DVDs, DVD-As and Blu-rays, too. I unearthed a few 24/96 and 24/192 stereo DVD-As, as well as a couple of CDs, and through the D.BOB, all of those PCM sources sounded fine.
Why didn't someone do this before? GeerFab's Eric Geer says it hasn't happened before because it's complicated. He had to solve three problems at once: extracting hi-rez audio, keeping HDCP copy protection intact, and outputting DoP over Coax and TosLink. It took him three years to solve it. Some readers will have no use for the D.BOB. Some may find it expensive, a shade under $1000. A few may be intimidated by lingering concerns over the legality of such a device. Many, though, 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, May 2020
Wouldn't it be nice if we could play our SACDs with the DAC of our choice? Enter GeerFab's D.BOB.
The D.BOB does what it claims to do.
- Extracts DSD64 and PCM up to 24/192 from the HDMI data stream from a player/transport with HDMI out
- Outputs DSD64 via the DoP (DSD over PCM) protocol and hi-res PCM up to 24/192 through the S/PDIF Coax and Toslink Optical outputs to an external DAC
- Fully HDCP (High-bandwidth Digital Content Protection) and copy protection compliant
- HDMI pass-through for player menu settings and other video uses
- Mini-USB for firmware updates
- DC 12V input for battery power (AC to DC adapter included)
