HA-3A
When exquisite design accomplished by first class engineering, when aesthetic backed up by rigorous production.
The HA-3A vacuum tube headphone amplifier let you enjoy your beloved music through your choice of headphones or earphones in a dedicated, engaging, and indulging retreat. HA-3A might look compact and simple, but Cayin has devoted our renowned engineering, decades of audio equipment manufacturing and carefully selected performance-based components to make this happen.
Carefully Selected and Hand-matched Vacuum Tubes
Driver Tubes
Dual 12AU7/ECC82(Matched Pair) from JJ*
Output Tubes
Dual 6V6S (Matched Pair) from JJ*
Clean Power with Minumum Interference
HA-3A uses an RCA 22DE4 as a rectifier tube, one of the best versions of 22DE4 available in the tube market.
While converting the incoming power source to DC current the 22DE4 rectifier tube minimises interference and provides clean power to the amplification circuit.
The Hidden Details
The chassis and transformer pots are treated by our proprietary 14 rounds of crafting process composed of scratch, spray, sanding and baking.
The high gloss final finishing endows a refined and delicate texture as well as protects the amplifier during years of long service.
Impedance Matched Phone Output
Our engineers have optimized HA-3A’s output to handle the headphone loading according to three headphone impedance settings:
Low: 8Ω ~ 64Ω
Medium: 65Ω ~ 250Ω
High: 251Ω ~ 600Ω
Three XL Aluminum Foot Pads
A set of three 39x18mm XL shock-absorbing aluminium foot pads to provide firm and stable amplifier placement on any hard flat surface.
2-rear & 1-front self-levelled placement to handle the extra weight on the back of the amplifier due to the power and output transformers.
Single-ended Vacuum Tube Circuit
The HA-3A vacuum tube amplification is designed as a 2-stage single-ended circuit.
The 12AU7/ECC82 driver tubes will amplify the voltage level of the incoming audio signal so that the 6V6S output tubes will perform their amplification at a very linear condition.
Single-ended circuit design displaces the beautiful tone of your vacuum tubes without any cancellation.
Single-ended uses matched pairs instead of matched quad-set tubes, you can enjoy greater flexibility when you perform tube rolling.
Carefully Optimized Headphone Outputs
6.35mm Single-ended
4.4mm Balanced
4-Pin XLR Balanced
The 4-Pin XLR output is a full-fetched output but the 4.4mm output is optimized for a wider range of headphones, including high-sensitivity portable headphones.
Anti-inference Design
Special shielding and anti-shock design remove microphonic effectively.
60 seconds start-up delay circuit
Enhances circuit protection and minimizes pop noise during start-up.
High-Quality Volume Control
The High-performance 50KA*2 Dual Unit smooth potentiometer from ALPS offers durable, high-precision volume control with excellent operational fee.
Bundled Protection
Specially designed vacuum tube shielding cage to protect users from touching the red hot vacuum tubes during operation.
Dual Inputs
Balanced (XLR) and Single-ended (RCA) to cover a variety of inputs. Balanced input will go through a pair of input transformers, and the + and - half cycle will merge to become a single-ended signal.
Transformer-coupled, Balanced Driven
The 6V6S output drives a pair of proprietary output transformers that supports single-ended and balanced headphone outputs.
The secondary winding of the output transformer provides an alternative phase and composes a balanced output, enabling a balanced driver from a single-ended vacuum tube amplification circuit.
Both single-ended and balanced headphones are
“original” outputs from the transformers.
In-house Designed Premium Power Transformers
Cayin always designs, wind and use high inductance, high-efficiency power transformers in our products.
Reinforcing shielding design minimizes interference and noise while ensuring HA-3A to work in the best condition.
Point-to-Point Wiring with Craftmanship
Time-consuming, shortest signal path, better attention to detail, the entire circuitry is hardwired by skilful craftsmen.
Implement circuit design with a high level of transparency and refinement, improving overall efficiency and conductivity.
