I2S input: problem with 705/768 frequency

I have: Reference + DD and Renderer and I2s inputs, Antipodes K50 streamer. Reading about many people here on the Forum who appreciate PGGB files, I installed the program to do some tests. A problem emerged: the oversampled files at 706/768 all sound distorted on I2S and perfect on Renderer. Even with Roon’s oversampling it’s the same: if I send it to the Renderer sound OK, if I send it to I2S it distorts sound… so it’s not a problem of PGGB (which I didn’t like anyway!!) …

Since the Renderer is connected to the Antipodes server and I2S is connected to the digital outputs of the Antipodes Player, could it be a technical limitation of the K50’s digital outputs?

Any ideas? Grazie

Hello @Francesco ,

The Antipodes doesn’t support 705/768kHz via the I2S. It just sends out distorted noise. This is not an issue with the DAC or the I2S input, but instead a limitation of the I2S output of the K50.

Thanks Jonathan, is this a limitation on all digital outputs of Antipodes? For example it wouldn’t even work on USB (which I don’t have…)?

The USB should work great. We don’t support 768kHz via the XLR or Coaxial so I wouldn’t know if those outputs work at these rates.

I’ll ask Luca Righetti if he has a USB input to try and I’ll let you know. Thank you
