Jazz-FF - Made in Germany (Special Order Only)


Overview

This amplifier may use a relatively simple (but sturdy) enclosure but at the inside it offers many technological ingredients not found in any other headphone amplifier in this price-range.

The JAZZ-FF not only uses the concept of active balanced ground but also has a discrete volume control (32 positions, two gain settings).

Tis volume control is technically very sophisticated. The position of the potentiometer is measured with the use of an AD-converter. The output of this converter is then used to set the proper volume level with a number of electronic switches. There are a total of 32 levels which allows for sufficient small stepsizes and a very analog feeling. The advantages are strongly reduced channel-imbalances and a much cleaner and more detailed sound.

Of course this amp also has our proprietary crossfeed filter incorporated which helps to strongly reduce listening fatigue.

The application of the FF-technique results in an extremely high level of micro-detail without any harshness. Sound is smooth and silky and this amp is especially recommended for acustical music (classic, jazz, ...)
