The stereo amplifier, CA-2100 is rated at 100W and per channel at 8Ω. The CA-2100 establishes a new entry-level Classé performance benchmark. Design features include balanced circuitry, overbuilt power supplies and oversized output stages to ensure the highest performance at every output level, with any loudspeaker.
