I've been waiting for this amp ever since Jason first mentioned it. I love tubes in general (I collect and restore old Tektronix 500 series oscilloscopes) and tube audio in particular. And I happen to love planar headphones. Ideally driven by tubes (Incubus) or tube hybrids (Mjolnir).
Ordered the Folkvangr yesterday about 930 AM EDT. It's listed as "In Production", so hopefully I'll see it late next week.
Ordered a Gungnir last week, it shipped yesterday, arrives on Saturday. As do my in-laws. I may get as far as unboxing it and powering it up, probably won't listen to it for a few days. Schiit DACs always need time to warm up and settle in after arrival. I'm really interested to compare the sound of the Gungnir to my Bifrost 2.
Assembling a frame now using black MakerBeam components (kinda like minature 80/20 extrusions) to hold the Folkvangr, my Mjolnir 2 above the Gungnir. The Incubus will sit off to the side of the Folkvangr, my streamer will sit below it.
Tubes - I will probably swap out the 6n1p with Raytheon 6BQ7A which I've found sound the best to my ear for tonal balance and spaciousness. I've also got some Amperex 6DJ8s I can give a try as well, though so far in both my Valhalla 2 and Mjolnir 2, I've really come to like the Raytheon 6BQ7s.
Headphone choices, I have a few. HD650, DT990, HE400, LCD3, DCA Ether C. The DCA Ether C may not be compatible even with the impedance multiplier on as they are ~13 ohms. They do sound great with the Mjolnir 2 (bought expressly to drive the DCAs), so that may be their permanent pairing. Proof will be in the listening.
The Folkvangr is the first Schiit product that I've been able to buy at introduction. I'm looking forward to this adventure!
