While most tube OTL amps are really only designed for 300 ohm Senns and 600 ohm Beyers, Valhalla 2 stretches to include headphones that you’d never expect to use with a tube amp. Many people use Valhalla 2 with sensitive, lower-impedance headphones as well.
A Complete Desktop Preamp
Valhalla 2 also has preamp outs and a gain switch. Preamp outs let you connect your powered monitors, to give them some of what some people call “tube magic.” The gain switch gives you better control of both output level and impedance, for better matching to your headphones. It's easy to build a complete desktop system around the Valhalla.
Not Your Father’s Tube Amp
If you’re expecting syrupy, tubby, euphonically colored tube sound, you’re in for a shock. Valhalla 2 is exceptionally accurate, neutral, and resolving, without being strident or etched.
Designed and Built in California
The vast majority of the total production cost of Valhalla 2—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Chassis are made minutes from our facility. PCBs are done just over the hill from us, or done in NorCal. Transformers are also made in California. You get the picture.
