The
HA-1 is designed to provide a listening experience far superior to solid-state
headphone amplifiers, and other inexpensive so-called "tube" headphone
amps. We believe that we have succeeded, in a big way.
The HA-1 uses the ECC82 (the European designation for 12AU7) tube as a
voltage amplifier, and a pair of special triodes, the 7044, as output
tubes. The 7044 was
designed for use in computers, and makes an excellent low-impedance output
stage. In fact, the output impedance of the HA-1 is so low (around 35
ohms) that it can drive even low-impedance headphones, like Grados, with ease.
Even though the HA-1 is inexpensive, high-quality components are used throughout. Polypropylene capacitors, toroidal power transformer... everything you hope to find in a good piece of equipment is there. It is truly a marvel of affordable audiophile equipment!
