I am using the Gustard U18 with a Musician Pegasus DAC. I am using the I2S output on the U18 and the I2S input on the Pegasus. PCM audio seems to work fine, however the left and right channels are swapped while playing DSD audio. I have tried the 4 different modes on the U18 and the 8 different modes on the Pegasus, but the L&R channels are swapped on all modes for DSD audio. Is there something else that I can try? I am using this cable. Do I need a different type of cable?

It looks like pins 1, 3, 4, 6, 7, 9 can be matched. I noticed that pins 10 & 12 on the Pegasus are MCLK- & MCLK+ respectively, where on the U18 pins 10 & 12 are MCLK+ & MCLK- respectively. Is that an issue?

I appreciate any help. Thank You,

There was someone with the same issue at


I just had one of them last week, but looks like they solved it.

Thank you, but it appears that their solution was to swap the RCA cables, which would make PCM audio incorrect.

I swapped the XLR out cables, then was able to find the I2S mode where everything was backwards, then PCM and DSD came of the correct channel. I also had to experiment until the phase was correct for both types.
