Depends what phones you're driving really. Asgard works well with low-impedence models; Grado, Denon, Audio Technica and up to my HiFiMan HE-500, despite being an ortho. I also heard the LCD-2 pairs well with the Asgard alternatively.
The Lyr's for the higher end of the impedence scale, but I do caution you if you plan to use low-ohm models with it. A few people have already busted their $1000 Ultrasone and AKG phones because they didn't read the manual ( or lacked any basic knowledge of electrical engineering).

For you IMO, would be better off with the Asgard if you plan on getting it, since you seem to favor AT phones.
You can safely upgrade to the AT flagship and still be oozing musical goodness with the Asgard paired.

Still very much cheaper if you buy it individually compared to getting from a distro channel.

Ofc, this is excluding tax and other schiit...lol.

Hi, any experience on Fiio E11 and E17 on the amplification department compared to the govibe martini+ with dt770pro 80ohms? I dun actually need the DAC feature in E17..
