Will the Isolator pass DSD Data? Is it bit perfect? Will it pass all higher resolution PCM also?

The Isolator can reach full USB bandwidth of 480MBit/s and it will pass DSD data in a bit perfect manner without changes. This is also true for any other data format and of course for PCM audio. We have successfully transmitted 32 channels at 192kHz in both directions without failure.

Summary: it can handle all sample rates and data formats. Of course 384kHz and even the new 768kHz. PCM, DSD, etc.
