Well, my Susvara was connected to Ragnarok2 for the night, music paused, amp on (not doing that again, just for peace of mind). The system has a PS audio power plant P3 for clean power (we hope) and protected by a rackmount Cyberpower UPS. Dac is Holo May. Susvara fine in the night. Only other condition is a tower fan blowing very gentle air through the rack, as there's some warm network equipment in it.
The next morning, the Susvara isn't making sound. Both drivers have no continuity/resistance (trace must be internally broken somewhere). I shine a light on the drivers and they look OK. Ragnarok2 appears to be operating fine, May DAC fine, PS audio power plant fine. PS audio power plant has 9 years of reliable service; May DAC 6 months reliable service; Ragnarok2 6 months reliable service.
I test the Ragnarok2 for DC offset on the 4 pin XLR out, I'm not getting any. It would have to have somehow blasted both drivers with bad stuff in one night. I run logging on my fluke 289 multimeter for 30 minutes, nothing outside the normal (0.0008V dc average with minimal deviation).
Plan is RMA ragnarok, RMA susvara, and just for peace of mind decommission the PS audio power plant and replace with a simple Furman rackmount pro grade power conditioner.
Disclaimer: Rag2 and Susvara are two of my favorite products, and both companies have been extremely helpful in offering to fix things, but it's unclear what is at fault, hopefully we figure it out.
