Single owner from a non-smoking household, and purchased directly from Black Ice Audio in January 2026. It currently has and will be sold with less than 300 hours of use.

Included: four EL84 EH power tubes and four 12AX7/ECC83 signal tubes, power cable, remote control, and the bias tuning tool (PLEASE MAKE SURE TO FOLLOW BIAS INSTRUCTIONS BEFORE USING).

This will be shipped well-protected using its original box and packing foam. Happy to answer any questions and send additional photos upon request.

From Black Ice Audio:

The Fusion F11 is a dual chassis design laced with carbon fiber and mirror-finished glass panels decked out with LED backlit touch sensors, that provide a rigid home for one of the newest circuits to date. The Odyssey Circuit is a dual-phase V-drive circuit that is one of a kind paired with our custom designed German grain oriented silicon steel core transformer based on the Hafler design. With EL84 power tubes, it pumps out 23 - 25 watts of pure tube magic depending on the power tubes. Using the Exact Biasing Vu meter, biasing the tubes is a breeze. The F11 features 4 RCA inputs, a sub out, and a chunky metal remote to keep you in control. The F11 final assembly and burn in is done by hand in our Maryland workshop.

The F11 is a mighty headphone amp that uses the extremely musical EL84 tube. The headphone output is all tube, tapped from the speaker path with a resistor to keep your headphones safe.
