Cayin HA-3A

$2,399 $2,499

If HA-6A and HA-300 MKII were amps you would argue for, HA-3A is the one that's impossible to argue against. Cayin Audio managed to wrap a single-ended Class A 6V6 tube amplifier into a compact A4 sized package, for desktop headphone versatility.

Weighing in at just over 10KG, not one gram is wasted with Cayin packing their famed power and output transformer iron into even the smallest member of the pack. It immediately leapt onto Headfonia's Recommended Buys list for a reason.

HA-3A brings the benefits of transformers designed and built in-house to meet the demands of modern headphones – both planar-magnetic and dynamic, high or low impedance. [See Product Desc. For More]

Product Description

Flexibility might be the first topic discussed with the lightweight and compact HA-3A, but compromise in quality was never an option.

Cayin's point-to-point wiring is de facto again for signal integrity, and the EI core output transformers utilise their shape to take the transparency of 6V6 power tubes out beyond the human hearing range.

These power tubes popularised by their use in Gibson and Fender electric guitar amplifiers are run in single-ended Class A.

Linearity is a given through the holy grail of bias operation, even at this price point, while tube operating voltages allow for large operating points.

Distortion is below even the threshold of HA-3A's bigger HA-6A and HA-300 MKII brothers – clipping theoretically only occurring beyond the former's maximum power envelope. 

And any distortion will be of the even-order variety expected of tube amplifiers, for a smooth, warm and holistic sound. 25AX4GT tube rectification rounds out a fully-regulated linear power supply built around Cayin's in-house toroidal power transformer.

In there is Cayin's promise – for low cost of entry, weight and size, the flagship trappings of HA-3A are impossible to deny.

A regulated linear power supply, Class A bias, high tube operating voltages, low capacitances, even-order harmonics and EI core output transformers ensure Cayin's baby of the bunch gets mentioned over similarly-priced solid-state competitors, and even higher-priced tube alternatives.

For those shopping with limitations to size and weight, HA-3A absolutely sounds like an offering without limitations. Particularly if Audio-Technica, Sennheiser and ZMF Headphones are your typical port of call. 

As for those without space or weight constraints, make the HA-6A and HA-300 MKII your first candidates, or view Cayin's other offerings here and our other desktop amplifiers here.
