Why is ethernet streaming for dsd usually limited to dsd64?

Posted by: Zeny on 31 August 2015

is there any technical reason for this? the streamers of a number of other manufacturers, such as chord and ps audio, are also limited to dsd64. Just wondering

There are faster DSD rates available - DSD128 (128 times faster than CD's 44.1kbs) DSD256 & even DSD512 is being looked at

Problem is with replay, there is not much hardware to support the low numbers of higher rate DSD recordings.

I believe that you can only do DSD64 with the 40bit floating point support on the SHARC processors normally used.

Someone correct me if this wrong.

DSD over PCM (DoP) encapsulates a DSD64 (2 ch, 5.6448 Mbit total) bitstream at 176.4 kHz with 8 bits of header data / 16 bits of audio data per channel (stereo), though it is certainly possible to stream at higher rates by doubling the sample bandwidth to 352.8 kHz.
