Yeah that's part of why I said don't bother trying to look for a Spectral, it sounds great but ti's kind of a high-maintenance affair at the end of the day.
The power brick gets uncomfortably hot, I ended up taking the PSU out of its case and laying a heatsink on top with some random interface material.
There's a fan inside the DAC that maintains uniform temperature between the digital input and the DAC + analog output, but the entire thing still gets too hot. I think they were trying to keep the entire unit hermetically sealed, to maintain control over the internal air currents. After a few weeks I noticed that the faceplate was sitting slightly crooked. At that point it was already too late and now I have 4 hardened puddles of silicone on my glass rack. Anyone know how to clean that kind of stuff? I haven't figured out a chemical solution yet and my last resort is to put the BHSE underneath and scrape off the resultant mess of goo.

In other news, the Yggdrasil continues to be an enjoyable listen. The way it depicts the soundstage is really interesting and addictive. Because of the architectural similarity to the SDR I'm personally attributing most of its character to the filter, but who knows. Looking forward to actively comparing it to the Segue, hopefully tonight.
At the risk of sounding shilly, it's worth taking advantage of their 15 day trial once they get production under control. The effects will be noticeable even if you don't subject it to 700 years of burn-in/uptime. Supposedly they also run them for 72 hours before shipping out
