Haha I'm glad you're enjoying the pairing. I just received mine yesterday but only had about 30 minutes to give them a listen. Initial opinions are that the mids and highs sound incredibly great. That is some amazing clarity. However, the lower end (bass) didn't seem to punch as well as my Marantz. Maybe the lower end isn't Schiit's specialty or maybe I just liked how the Marantz handled the lower end more.
Also I feel a little worried for my own well being because I found the early volume stages (7 o' clock to 9) to be pretty quiet so my volume was set at 10-12. I don't know if its my songs or the increase in volume is more gradual in the Lyr. No doubt it has plenty of power though. I just feel quite uneasy with the volume knob set so high on an amp that has been advertised to have stupid amounts of power underneath :P
Since I'm not the only one whose recently received the Lyr, I'd definitely like to hear all the impressions so far I don't know if there is such a thing as burn in for amps. Even for headphones I don't think it affects the overall signature too much at all. Coming off my first listen though, I really hope the bass opens up a bit more.
The Lyr will open up in due time. I also had to crank up the knob to 11. For what it's worth it's now at 10.
