HCA-800II

About the HCA-800II

The Parasound HCA-800II is a high-performance stereo power amplifier featuring dual-mono construction and a fully complementary symmetrical amplifier topology. It delivers 100 watts RMS per channel into 8 ohms in stereo mode, 150 watts per channel into 4 ohms, and 260 watts into 8 ohms in bridged mono mode. The amplifier operates in Class A/B and uses 60MHz Sanken output transistors, contributing to its clear sound, minimal noise floor, and remarkable bass response. It has a frequency response from 8Hz to 90kHz, total harmonic distortion (THD) around 0.05% to 0.25% depending on power level, and a damping factor greater than 100, which helps control speaker drivers effectively. The power supply includes a 700VA toroidal transformer and 30,000µF of gold capacitors, ensuring robust and stable power delivery. The unit weighs approximately 23 lbs and measures 17-1/4 x 3-3/4 x 11-3/4 inches. It is known for its reliability and sound quality, making it a favored choice for audiophiles seeking affordable high-current amplification. The amplifier was manufactured in Taiwan and was available from the late 1980s to the 1990s. It is still sought after on the used market for its sonic performance and build quality.
