Firestone Audio - Bobby - Pure-Class-A, Fully Balanced Headphone Amplifier

100% Positive Reviews
Rated #124 in Desktop Amps

Pros: Well balanced sound, black background, ultra precise volume control, low or high impedance jacks (in single ended mode) to adjust for flavor,

Cons: 0 ohm output impedance on one jack would be ideal, I dislike the 3-pin XLR balanced style

See my full review HERE. In summary, this is a well rounded, high performance amp that really offers a lot for the price. It's neutral, clear, and balanced - literally speaking and in terms of sound. Not sure why it isn't more well known.
