Description :
The Parasound HCA-2200 mk2 power amplifier was designed by one of the world's most renowned circuit designers, John Curl. He has designed some of the best sounding amplifiers in the world and this is one of the finest ever made. Every part, every direct-coupled circuit, has been painstakingly selected for optimum musical quality on the finest and most challenging music and loudspeaker loads. It has balanced XLR and RCA inputs and the amplifier can be run in Bridged Mono for even more power, up to 1 kilowatt of power. It also has two independent 1200vA toroid power transformers, independent transformer windings for driver stage regulators, higher driver rail voltages and independent regulation to prevent sag, and 100,000uF computer-grade, multiple polystyrene bypass capacitors in power supply. On the dual mono circuit there are cascode Class A input stages with matched J-FET pairs, hand picked MOSFETs in high voltage driver stages, output transistors direct-coupled without inductors, and linear tracking, instantaneous acting DC servos that are direct-coupled audio circuits with 0.3Hz rolloff.
The Parasound HCA-2200 mk2 delivers clear and focused sound at a high power level without any hint of distortion. The amplifier exerts a strong control and produces tight and deep bass. It also has great midrange and extended treble. The highs are detailed and clear even at low volume levels. It takes a masterpiece of an audio system to push the highs to extreme volume without missing a beat. It is smooth with excellent dynamics that eliminates any sense of stress or strain. The amazing resolving power makes the music seem more realistic and tangible. Even at low playback levels the amplifier has incredible performance. The soundstage is wide, deep and detailed without being harsh. Audiophiles will be hard pressed to find a better quality amplifier than the Parasound HCA-2200 mk2 for its price range.
