Amplification in HA-6A

The advantage of transformer coupled tube headphone amplifier is that the matched pair output transformers can deliver genuine balanced driven output of excellent soundstage and separation.

Purist Power Management

Multi-stage independent Power Supply.

Voltage amplification employs independent regulator design.

Minimum ripple effect of power interference ensures outstanding audio performance, free from any grain and harshness.

Serious Components for Unbeatable Price-Performance

Matched-pair Custom Build EI Output transformers

Enable complicated multi-layer winding and multiple impedance output to match with different needs.

Carefully matched output will sound balanced, natural and realistic across the complete audio spectrum.

Custom Build EI Power Transformers

Require more space but extremely stable and cost effective. Very Musical with addictive mid-range performance.

Transformer is the corner stone of tube amplification. We are determined to meet all functional and audio requirements, so we designed and custom-built all the transformers of the HA-6A in-house.

High-Precision 24 Steps Potentiometer

Matched-pair resistors, low noise, durable and reliable.

Premium shield silver-plated cable

Minimize interference during transmission.
