Preamp sending amp into protect

Hello everyone,
I recently took delivery of a Denafrips Athena preamp and their Apollo power amp, as well as a Lumin U1 Mini and an Ares 2 DAC. When the amp is connected via xlr outs to the preamp, it goes into protect within a few seconds. However, when connected directly to the Ares 2 DAC, everything is working as it should. Before I got the amp in I was using the xlr outs of the preamp to connect a set of powered monitors, which worked fine. I’m confused as to what would cause this issue with the preamp and amp combo. Any help would be appreciated.

Same brand amp fails fed by their own pre?
Time for support from the manufacturer.
Hope you understand Mandarin.

Did you try reaching out to Alvin as he is a better source than this forum of non owners.

Sounds like a kind of DC offset.

Went through some troubleshooting steps with Alvin and the NA repair rep and it seems this only happens when the left channel on the amp is connected to the preamp. Connecting just the right has no problems

Check your speaker cable connections. They can come loose, or, be too close to the opposite binding post.
