I could test a single ended input to the UcD but it would require a cable that I don't have. Focusrite is 1/4" jacks and UcD has XLR input. I would need to cannibalise some other cables to get the right connectors. I have run out of test time now and don't see the opportunity for more for quite a long time.

I checked DC offset on the LKS DAC and it is very low at 0.6mV, the balanced output is trimmed to 0 but that doesn't change the single ended output offset at all.

I had a few Jriver crashes after so maybe Jriver and the cheap Amanero clone caused a DC spike that shut down one channel, the other answer is that the power supply for that channel is faulty, and I would prefer that not to be the answer. I put the Focusrite interface back in so I will see if that helps.

I may have found the cause of my amp shutdown issue, not 100% confirmed yet though.

It has happened every time I played Flamingo by Infected Mushroom, which seemed a little too coincidental hmmm....

So I checked the spectrum with Audacity and got this, that level of ULF could be enough to trip the DC protection in the First One 1.4 as it is DC coupled. Time to try a steep High Pass at a low frequency and see if that fixes it.

I tried a Linear Phase 96dB low cut filter at 15Hz Q1 which is basically a brickwall and it wasn't enough. I got 4:30 into the track before the left channel shutdown again....

Looks like I'll have a try a coupling cap and see if that stops it from tripping.

Good luck troubleshooting, if you need another trigger it could be the track you shared that ended life gkh's Yamaha's.

Here another trigger candidate in CD quality, length is very short and first two seconds create below spectrum.
