Designed with the breakthrough Odyssey Circuit
The new Black Ice Audio F11 is a state-of-the-art stereo tube integrated amplifier sporting a new breakthrough circuit design by Jim Fosgate - that includes touch sensors, LEDs, and a look that wants attention.
The dual chassis design is laced with carbon fiber and mirror-finished glass panels decked out with LED back lit touch sensors, that provide a rigid home for the one of the newest circuits to date.
The Odyssey Circuit, designed in 2015, is a dual phase V drive circuit. With El84 power tubes, it pumps out 18.5 watts of pure tube magic. Using the Exact Biasing Vu meter, biasing the tubes is a breeze and the F11 becomes a 18.5 watt heart of your system.
When it’s time for the neighbors and the kids to go to bed, the fun doesn’t stop. Plug in your headphones and press the headphone button to move your music from your room to your own personal space.

SIGNATURE SOUNDThe signature sound of the F 11 is a fine line of transparency and musicality that results in an accurate, yet organic & natural washing-over affect.
Because of this wonderful mix, choosing the right tube will have a major impact on the overall sound of the amplifier.
Unlike other manufacturers where the circuits in their equipment require you to use a certain type of tube and brand with their products, the Black Ice Audio amplifiers make it easy for you to roll different types and brands.
With the use of the on-board meter and the tuning wand provided with the product, you’re able to bias accordingly. It’s that easy.
PREAMP TUBESThe stock preamp tubes you can choose from are the 12ax7 by Tung Sol or the 12ax7 by Svetlana.
The Tung Sol 12ax7 is a very clear sounding tube with crisp sparkling highs, focused mid range and a tight base. Where the Svetlana 12ax7 will give you smoother highs, a warmer, fuller mid range and a textured bass. Both tubes give a very three-dimensional holographic soundstage.
POWER TUBESThe stock power tubes are Electro Harmonics EL-84.
The EL-84 will provide the listener with a sound that is well balanced for simplistic music like jazz and vocals or dynamic music like rock, hip-hop and big classical.. The sound will have neutral highs and mid range with strong controlled bass. The bass will roll off between 22 and 23 Hz providing more slam and dynamics.
TUBE ROLLINGIn regards to tube rolling, the owner of the F 11 can enjoy exploring and doing a little research. This includes learning that tubes from different regions of the world produce different types of sounds in the amplifier.
For example; Tubes from Russia will have a very clear defined type of sound Extended highs, focus mid range, and a tight bass. Where as tubes from America are going to have smoother highs, fuller mid range and more of a boom boom in the bottom end. You will find tubes from Germany are articulated compared to the tubes from China were the highs are rolled off with a very lush mid range and a bit of a sloppy bass.
Knowing where tubes come from will help you decide which sound is right pair for you and your system.
Circuit board layout
Only two circuit boards: Control board Signal/power supply board - integrated to lower labor cost to continue offering price to performance for the customer. One reason we are able to offer the prices we do. (Less connections for less chances of failure).
Tube biasingWe know how difficult and time consuming biasing tubes can be. So we incorporated Exact Biasing to the design to make it as easy as possible. The centralized back lit Vu Meter and the Biasing selector switch make checking the bias amperage in real time simple with a turn off the knob. Using the provided tuning wand and the back lit Vu Meter each tube can be biased exactly where you want it.
Touch sensorsWe wanted to incorporate led back lit touch sensors to the design to make the front panel as sleek and smooth as possible and to have that seamless mirror finish. Having touch sensors the user interface is as modern as the current cell phones and appliances on the market today. We use the most up to date capacitance sensors to handle the extreme temperatures that tube amps generate yet allowing the user to use the slightest touch to command.
ChassisThe Dual chassis is an unique design. Each chassis is 3mm thick Stable and sturdy construction Aluminum backed glass on transformer cover. Face plate is steel backed glass.

The ResultsMore sparkle in the highs, smoother yet more detailed and defined.
Mid range has more nuance, emotion, accuracy and maintains control of the focused 3 dimensional image with Increased weight, air, and dynamics.
Bass becomes tighter, with more detail and texture.
