Brand new in box EU 220V Schiits crazy ass 10 tube, DC coupled, OTL headphone beast. I haven’t had a chance to try this out but I thought it was such a nut headed idea I got one- one of 250 ever made. Likely won’t see crazy Schiit like this ever made again. Hard core collectors item. From Schiit:

-two matched 6N1Ps for input and voltage gain, and eight 6N6Ps for output. Eight separate DC servos keep the output tubes at a low level of offset, and an analog-computer-style protection system monitors and mutes the output in case of any tube mishaps. At idle, the 10 tubes run 7.2A of heater current and 100mA of standing bias.

In addition to the tubes, Folkvangr offers a switchable impedance multiplier—an electronic circuit that operates similar to a transformer. Stoddard emphasizes this is "not a buffer, it's output is in parallel with the tube stage, and has the same distortion profile." The impedance multiplier makes 32 ohm headphones look like 256 ohm headphones to the amp, which is a much better load for tubes. The impedance multiplier is also completely switchable out of the circuit, so owners can choose to use only tubes.

Folkvangr also features an oversized, 400VA transformer and discrete-regulated high-voltage rails at +/-100V and +200V. Coupled with over 10,000uF of filter capacitance (yes, on a tube amp), Folkvangr is truly overbuilt.

Prospective customers may also notice the new-style, new-form-factor chassis design, which provides maximum tube exposure for best heat dissipation.

Like all Schiit products, Folkvangr is made in the USA—specifically, designed and and built in California. The vast majority of the total cost of the product, including chassis and PC boards, go to US-based companies manufacturing in the USA.
