FEATURES

The following section describes the HH-1’s basic features. The features are subject to change

without notice or obligation.

PRODUCT FEATURES

The new HH-1 headphone amplifier from Cary Audio is an all-new 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 a 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 HH-

1 headphone amplifier, and ensures that all circuits are fully stabilized before each listening

session.

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.
