I am using a Geerfab DBOB to send DSD and 24/192 from a sony universal player to the coax in the DSD DAC. The DSD 1 bit signal from SACDs is perfect and sounds great. But if I play Blue Rays the 24/192 does not work. Sounds choppy, unsyned. The 24/96 is fine.

Does the DSD DAC except 24/192 via COAX??

Welcome to the forum.
As per my experience, yes it does. S/PDIF (coax) accepts 44.1kHz to 192kHz 16bit and 24bit, as well as DSD 64

On BluRay, it will “dumbconvert” to 48kHz/16Bit. Get this :

HDMI/MHL to IIS I2S HDMI IIS I2S Separate Extract Audio I2S/DSD/Optical/Coaxial

And then download makemkv (makemkv) and copy your BluRay’s onto your network drive. Play those files via the coax or I2S inputs and the copy protection will be removed thus allowing you to spin SACD’s natively (I2S only) and playback BluRays are the original PCM rate.

Thanks for your responses but… Has anyone tried the GeerFab D.BOB.

  • 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

All works perfectly except when I send 24 192 it does not work. Yes I get DSD 64 from SACDSs, yes I get 24/96 from DVDs and BDs. The only issue is that 24/192 does not work. Any others have this issue??



Got my D.BOB this weekend and finding that I’m also having the same issue with 24/192 playback while DSD 64 and 24/96 work great. I would love to find a resolution to this as I have quite a few pure audio bluray discs that are 24/192. BTW, I did try this with another DAC that accepts 24/192 through coax and it works fine, so it doesn’t appear to be an issue with the D.BOB.

Discovered another DAC in my possession (Exasound) will accept 24/192 via coax input, and the D.BOB works fine with it. Since I’ve now tried 2 other DACS that accept 24/192 output from the D.BOB, I’m wondering if this means that my DS Sr. has something wrong with it’s coax input since it has issues with that sampling rate?
