Cary Audio HH-1 Headphone Amplifier


Used 8.5/10


The HH-1 headphone amplifier from Cary Audio is an all a hybrid design, featuring a tube input stage feeding a single-ended MOSFET output stage. These MOSFETs were chosen as they
have sonic characteristics very similar to tubes, and the entire amplifier operates fully in class-A at all output levels. It is extremely simple to connect and operate, featuring a pair of RCA input jacks and a loop-through output pair, a power switch, and volume control.
Top quality parts are mounted on a heavy gauge fiberglass circuit board, and only two stages of amplification are used for the shortest possible signal path. A power transformer, rated at three
times what is required for the amplifier’s design, feeds a fully regulated discrete power supply for the best sound quality. It is designed to drive headphones with an impedance between 30 and 600
ohms. A 30-second muting circuit prevents any annoying pops and clicks when turning on the HH1 headphone amplifier, and ensures that all circuits are fully stabilized before each listening
All of the design and construction features would be meaningless if they didn’t contribute to both superb sound quality and long-term reliability. Like all Cary Audio equipment, the HH-1 headphone amplifier is engineered to provide accurate and lifelike musical reproduction, and to do so for many years. The HH-1 has beautiful cosmetics and contains the latest technology and quality components to ensure that you enjoy your music, whether used as a stand-alone system in an office or as part of a serious main music system.
