Aegir, Freya, Bifrost 4490 and a Skoll, just pre-Forkbeard. Across the room, next to my recliner is the venerable 1st gen Lyr headphone amp. For our safety it's connect with 70' of Mogami W3106 dual channel stereo mic cable through an ART Cleanbox Pro. I run the Lyr wide open and the Freya in SS gain mode. It's excellent and nobody is gonna bust a hip tripping over my HP cable. Trippin' maybe, but not tripping. I like the Skoll very much with my hotrod DL-103r, but I want to try it with the Denon SUT next. Oh yeah I have a Bifrost Uber to compare against the 4490, but it's the healthier choice since the 4490 is a medical chip
I'd be hanging out in the Schitt'rs headphone demo room a lot if it wasn't a 130 mile r/t
