General Information
Schiit Audio’s first limited-edition amplifier: the 10-tube Folkvangr. Folkvangr is a DC-coupled, output transformer-less (OTL) and output capacitor-less (OCL) headphone amp.
Folkvangr uses 2 matched 6n1p for input and voltage gain and 8 6n6p tubes for output.
It’s said to dissipate 100W to produce about 1W of output. @Jason Stoddard does not explain this product in his unique style:
“So, how do you explain a 10-tube headphone amp that, gets super hot, measures terribly, connects your headphones directly to the tubes, and is launching at a time when tubes, well, are still kinda stinky to get ahold of? In short: you don’t.”
This passion project is rather interesting. It answers the designer’s question of “what do tubes really sound like?”. It introduces a hitherto unseen design element for Schiit (the recessed top). It is single-ended only, where most of the company’s top range insists on supporting balanced i/o. It has an Aegir-like on/off switch. There are some rather impressive numbers inside (400VA transformer, discrete-regulated high-voltage rails at +/-100V and +200V, >10,000uF of filter capacitance). It also has the necessary protections to survive tubes gone wild and another very unique feature: an 8x impedance multiplier switch so low-impedance headphones play better with the amplifier.
Folkvangr is limited to a 250-piece run. It’s likely more black units than silver were produced given customer preferences discussed in meets, interviews, and such. It was priced at $1799/$1849 including tubes. Folkvangr was introduced in June 2022 and sold out in October of the same year.

The Utopia’22 did great!
They sounded fuller to me with high gain. I can’t say there was anything in the Folkvangr that gave them something extra, or took anything away. They pretty much allowed the amp to show its width and depth and stayed out of the way.
