Probably should have posted this here, not in the "Schitt Happened" thread.... My Vidar arrived a few days ago, and i managed to run it into protection after a couple of hours at *very* high volume into 4 ohm speakers. Running via a Joty to VAF DC-7 Gen 4 speakers, I had the Joty on high gain and at close to 3 o'clock. It sounded awesome Normally I wouldn't listen that loud (wish I checked the SPL, will do that another time). When it shut down I checked the temp with my hand, and couldn't leave my and on the heatsinks, they were hot. 61 degrees C when I checked with my infrared thermo. Is was about 26 degrees ambient in the room. In less than a minute it was running again, the protection seemed to work flawlessly. So I found the limits in my system. I seriously doubt I would go anywhere near this normally. Yesterday at much more sane levels, the Vidar sounds excellent.
