I have been running the Tyrs for a couple days now and thought I should drop a comment out here. General observations are as follows: They run much cooler than my Vidar. They have not gone over 92 degrees according to the temp gun, regardless how long they have been on. They have primarily been attached to my Salk Veracity monitors. The Salks use a Seas excel 16 cm driver and a RAAL tweeter and have always been exceptional at retrieving detail. However, they are rather low sensitivity. The Tyrs have actually caused the Salks to achieve a speed and bring out micro-detail which my prior amp did not. In addition, the bass, while always surprising for monitors this small (which will go down to 37Hz), was never as fast or as strong as it is now. It has caused two bass traps to be ordered for behind the listening position as well thicker panels to absorb the bounce behind the speakers. A quick test with the Maggie LRS and I'm hearing bass that is much stronger and more controlled than with the Vidar/Freya+ that runs in the other room. For me, the Tyrs are a winner. They have plenty of power and what appears to be amazing control over the drivers. They bring out so much detail, but are in no way harsh. Definitely an iron fist in a velvet glove situation. YMMV. As others have done, I also had to move my speakers a bit farther from the wall and also a bit farther apart as it seemed to make things sound more "right". The weekend will allow me more time to mess around with them. I'll see how the Freya S versus + changes things. I can also try the Maggies a bit more, and possible move everything to a larger room for a while. I'm loving them so far. Definitely keepers.
