Had a bit of an accident today. Won't bother you with details but the result was two destroyed Placids. An old one and a new HD... Oh well... one detail then: I had them out to check and something heavy fell on it. It was not my fault and the person who did cause the accident is still alive.
Switched to the DIYINK 5 V supply.
I managed to remove the connector on the Amanero without any damage.
So everything is playing again. On 192 that is. Still distortion on 384.
Russ, you asked me to check supply sag. When the Placid for BIIISE was still in place I measured the the output of the Placid without BIIISE attached. It w s a bit low so I turned it up to about 600mV. When I connected BIIISE it dropped considerably. (If I recall correct something like 190mV). Is that what you meant?
Also ordered the UFL cables today. When checking the UFL connectors on my BIIISE I noticed my soldering skills were not that great. (I actually improved them over the years 😉 ) Could that cause the problem it won't play at 384?

I am most interested about the 1.2V trident - it can sometimes sag a bit too much at 384Khz, Be very very careful when checking it. Remember you must be measuring when the music is playing to see any effect.
Hmm few observations:
1) The 1.7V reading at idle seems quite high - you may want to double check that. 1.7V is way too much for the chip to handle safely.
2) The 1.08V reading is definitely low (sign that the trident is starved for current) - You can add 27-35R at R4 on that trident to give it more current. (any 1/4W metal film type will work fine)
3) Also make sure the VD supply to the B3SE and the supply to the Cronus don't dip below 5V when 384khz music is playing.

How sensitive is Cronus for a good power supply? Does it neet a 'high end' power supply to get the best result or will it be just as good with a simple power supply?
It has very good local regulation - but as with anything - the cleaner the input the cleaner the output. 🙂
A small step for mankind, a giant step for a man! A 30R resistor solved the problem! Thanks Russ!!! (And Grael and Brian)
Next step: order a new Pacid HD and move the Cronus-Hermes-Amanero next to the BIIISE with the longer UFL cables.

🙂 Just ordered a new Placid to replace the crushed one 🙁
Been listening with the DIYINK PSU connected to Cronus and BIIISE. There is a difference between this PSU and the Placid so I won't comment about sound to much but my first impressions are: a bigger soundstage and more detail. So far I'm really happy! 🙂

Any chance of posting a photo of the resistor you have installed it may solve an issue I've had.
Well, everything is working as advertised! 🙂 When I started using my WaveIO I first used it USB bus powered. Later I used a separate PSU for the WaveIO which gave a nice improvement. Amanero is also bus powered, is there any benefit in powering Amanero with a separate PSU? Anyone tried?

No value in this case - because the amanero does none of the final signal processing. 🙂 You are already cleanly supplying everything that matters. 🙂 The amanero is completely isolated in every sense - physically - and signals in time domain.
