SACD Stack

Not Just for SACDs

If you’ve been relying on the internal DAC on your universal player* or AVR for playback of Blu-Ray Audio, DVD Audio, or standard CDs. D.BOB will allow you to take advantage of your high-end DAC** to enjoy those formats to their ultimate ability.  D.BOB can also improve the audio quality of Apple TV and other media streamers.

The Promise:

Originally developed by SONY and Phillips, Direct Stream Digital (DSD) is arguably the best recording and playback format ever developed for digital audio with its 2.8224 mHz sampling rate (64 times the sampling rate of CDs). The introduction of Super Audio CDs (SACD) as the delivery method for DSD held great promise for audiophiles everywhere. 

The Problem:

DSD sounded good, so good in fact that copyright holders were concerned about releasing music at such a high resolution because of the rampant piracy of traditional CDs. Copy protection restrictions were placed on SACD players that blocked the playback of the HD layer of SACDs through digital outputs and it could only be played back through analog outputs. That meant the audio quality was limited to the quality of the player’s onboard DAC, which was often compromised.

The Solution:  

Introducing the D.BOB Digital BreakOut Box. GeerFab Audio has developed an innovative solution that allows you to legally harness the digital audio transfer of DSD audio from SACDs through the HDMI output of universal music players and feed it though D.BOB’s S/PDIF coax or optical output for conversion through your favorite high end DAC. See System Requirements for tested and confirmed universal players and DACs.
