Black Ice Audio Fusion F11 Integrated Amplifier


Arizona Sales Only

The Black Ice Audio F11 and F22  integrated amps display an aesthetic that melds classic tube-and-transformer with more modern style and conveniences, such as touch-sensor buttons on the front panel, a headphone jack right off the output transformer, and an included tube-biasing tool that’s easier to use than the typical tiny screwdriver. Both amps were created around Jim Fosgate’s Odyssey dual-phase V drive circuit, a fully balanced differential push-pull design. The F11 delivers 18.3Wpc and uses new-reissue 7189 output tubes, said to allow more voltage to be applied for more sonic sparkle, weight, and punch. The F22 uses EL34s for output and 12AX7s for the preamp stage and features a Hafler hybrid design on the output transformers that’s been tweaked to enable these amps to drive relatively lower-efficiency speakers.

Remote control.
