nothing1 Posted April 20, 2012 Posted April 20, 2012 i was just wondering is it possible to pass a 32 bit signal through a digital coaxial (or optical) cable?
nothing1 Posted April 21, 2012 Author Posted April 21, 2012 i want to get the most out of my new minimax dac plus. I have a lot of sacd iso's which i can convert to 32/176 with Weiss Saracon and just wondered if it was worth the effort.
Lil Caesar Posted April 21, 2012 Posted April 21, 2012 Yeah COAX will handle it, optical cannot. But I'd question the value of 32bits, the last eight will most likely just be padding. Even 24 is usually never fully utilised, particularly when we are talking about transcoding DSD to PCM.

If you use digital volume control and have high resolution recordings like the sacd or PCM 24 bit downloads and have abundant hard drive space for parking the 36/176 FLAC's and a transparent system and great hearing then it may well be the way to go. Why dont you experiment with converting one DFF track to different bit-sample rates till you find where the performance edge is for you? Dont be surpised if its at 16/44 if you use a preamp.
NeoG Posted April 25, 2012 Posted April 25, 2012 You can have as many bits as you want as long as the right devices are on both ends of the cable Your aim is to set up a 32-bit playback pipeline, you need to check every link to make sure it won't truncate the signal along the way 32 bit Source - check 32-bit Player - check (foobar) 32-bit Audio Driver - Unknown 32-bit S/PDIF Output - Unknown 32-bit DAC - check If you use the minimax dac plus USB direct, the audio driver will go down to 24-bit. So your next step would be, what do you plan on using as your 32-Bit S/PDIF source from the computer, and have you checked it allows 32-bit output in the playback software.. I would personally also question the value of the extra bits, but this is pretty unexplored territory!
gavtron Posted April 26, 2012 Posted April 26, 2012 according to their website Kingrex UC192 supports 32bit spdif output.
nothing1 Posted April 26, 2012 Author Posted April 26, 2012 according to their website Kingrex UC192 supports 32bit spdif output. No from what i read it accepts up to 32 bit via usb but only outputs up to 24 bit through spdif From Website: USB interface : -USB 2.0 High/Full Speed compliant - Adaptive Clock Generator for Audio Streaming Synchronization - Supports CRC Error Correction for Playback Data.
