cello encore 150 amplifier

The Encore 150 Amplifier

The Encore 150 Amplifier is comprised of two solid state mono-power amplifiers with dual choke power supplies.

Input impedance is one megOhm and input sensitivity is high, permitting the Encore 150 to be driven by any preamp. Output impedance is low to ensure the best interaction with any speaker load.

The Encore 150 Amplifier’s sonic outputs include a tight bass and open highs. It offers the clear, balanced, effortless sound, which is the hallmark of Cello. It is ideally suited to systems that require medium to large amounts of power to achieve realistic performance levels.

The Encore 150 Amplifiers are individually handmade from the finest parts and materials and use proprietary Cello circuitry that represents state-of- the-art audio electronics.
