Cayin HA-3A Vacuum Tube Headphone HIFI Power Amplifier Graded Independent Power Supply Three Headphone Output Terminals
Cayin HA-3A Vacuum Tube Headphone HIFI Power Amplifier Graded Independent Power Supply Three Headphone Output Terminals
Two JJ6V6S imported vacuum tubes for single-ended pure class A power amplification
Two JJ12AU7 (ECC82) for voltage amplification
Hierarchical independent power supply with large signal-to-noise ratio optimization
The RCA 22DE4, which is highly praised in the same type of tube type, is used as the rectifier tube
Responsible for the independent power supply of the voltage amplifier stage and the low-noise voltage regulation circuit to ensure pure, low-noise and stable sound output.
Output power mono up to 700mW
High, medium and low impedance selection
Three headphone output terminals
6.35mm single-ended
44.mm balance
4-Pin Balance
Each headphone jack is independently optimized for tuning, among which the 4.4mm balanced headphone output jack is optimized for in-ear earbuds.
XLR and RCA line input
In addition to matching with desktop decoders or CD players, it can also be used with portable players through adapter cables.
The shell of HA-3A is carefully crafted with 14 spray paint and polishing process. The aviation aluminum alloy panel is used on the front, which has both beautiful and practical tough lines, adding a high-quality texture to the home space.
It is made by hand-built point-to-point wiring. The internal circuit of each HA-3A machine is carefully hand-wired by experienced technicians using high-standard wires and components. To ensure that the circuit has a higher pass rate, the transparency and fineness of the sound are better.
Adhere to the self-developed high-quality power transformer, which adopts high-purity copper enameled wire winding design, which produces lower magnetic interference than standard transformers. In addition, special research on shielding packaging technology and circuit protection measures further protects the power amplifier circuit from sound interference, and effectively Improve product life.
