The Balance Plus is an extremely quiet, high resolution phono stage capable of handling both MM and MC cartridges. It can be run in fully balanced mode using the XLR input and output, or in true single-ended mode using the RCA input and output (both not a mixture of the two modes). Additionally, it has the option of being run directly into a power amplifier via a high resolution attenuator located on the faceplate along with mute and fixed/variable selectors. This attenuator is also connected to an independent, high quality headphone amplifier. The audio chassis circuit board uses ultra high quality parts for all aspects of the signal path and is housed in an extruded aluminium block that protects against unwanted vibrations. The external power supply is housed in an identically-sized extruded aluminum chassis. Clearaudio's Accu Plus battery power supply may be added at any time, allowing the Balance Plus to run on pure DC power for even greater performance.
