To anyone interested...
The LISSTs are on their way back to Schiit. During the second day of use they started producing noise in the right channel. No signal being applied and Freya in mute mode. Something getting through that shouldn't have. Sounded like a short and, actually, a lot like a conventional tube going bad. Shut things down. Pulled the LISSTs. Installed a quad of conventional glass tubes. Powered back up. Everything okay...no damage done. Given the long expected service life of 6SN7s in Freya and their affordability, I personally don't see an advantage to LISST. Maybe if they ran cool...but they don't.
