Shiit Audio Valhalla OTL HEADPHONE AMPLIFIER

Great Amplifier with rich, warm sound. Been in use 100+ hours of listening. I hate to part with it, but I've fallen in love with a Mininote more or less rebuilt from scratch.

Valhalla is a Class A, single-ended triode headphone amplifier with no overall feedback and noninverting circuit topology. It provides classic tube sound and can drive headphones with impedances as low as 32 ohms.

All Tube, All The Time
The only active devices in the audio signal path in Valhalla are tubes. The 6N1P triodes input provides highly linear, low noise voltage gain. The 6N6P triodes provide good power output capability for a wide variety of headphones

4 Years of the original warranty remain and the amp includes large rubber feet.
