Distorted 24-bit/192kHz PCM using iFi Zen One Signature DAC?

Anyone with this DAC get a chance to play 24-bit/192kHz though the Toslink input?  I'm getting distortion despite playing fine through the coaxial input.  If I use the same Toslink cable and player to another DAC, the sound is fine.  




AES3 calls for 192 frames per block and 24 bit is fully supported so unless there is a hardware issue you shouldn’t be having problems. Since you had no problems using same cable on another dac I’d suspect it’s an issue within the Zen One. if trying a different Toslink cable doesn’t solve the issue I would send it back and exchange on a new one.

Does anybody know if the Zen Stream can output over SPDIF DoP in 24/96 format? My DAC accepts max 24/96 and need to listen to my DSD files on external SS drives.


I don't know about the Zen Stream, but to address my original post, iFi did eventually confirm that 24/192 is not supported on Toslink.  They were gracious enough to compensate me for not being fully transparent in their product specifications.
