LAIV Harmony

I’m running an Aurender N200 USB to a Denafrips Gaia 12th and then I2S to the Harmony. All formats work fine except DSD128. The left and right channels are swapped and this only happens on DSD. I’ve tried every possible pinout  configuration between the two. I also have a Denafrips Pontus 15th that works on DSD 128 so I’ve eliminated other components in the chain. Anyone else experience this? Thanks. 

He (Weng) also added that by adding the DDC I might hear very subtle improvements but not noticeable.

Most audiophiles here claim they hear a significant improvement from adding a DDC. Do they have better ears than audio engineers, are they exaggerating, or do they simply want to justify their spending?  

@kereru, Assume you have received your LAIV uDDC by now?  What are your impressions, and how does it compare to the other uDDCs you own or have tried?

@Audiostick I paused my uDDC pre-order for financial reasons so I do not have the uDDC yet sorry.
