The Performance Amplifier II

The Performance Amplifier includes many engineering features exclusive to Cello, which together provide unparalleled speed, clarity, impact, natural tone quality and reliability.

Each amplifier chassis has a balanced audio input, balanced bridging output, and four sets of barrier strip outputs. Three pin Fischer connectors are used to provide balanced line audio connections of the highest quality.

The cost of the Performance Amplifier reflects Cello's insistence on the most innovative circuitry and premium parts.

The Performance Amplifier offers a combination of sonic purity, power, build quality, freedom from obsolescence, and flexibility that makes a new level of musical integrity and system performance possible.
