A balanced connection separates audio channels, eliminating interference. This ensures a distinct tone and enhanced dynamic range within an expansive acoustic field.
A ø4.4mm connection cable has two polarised signals that cancel each other out, reducing unwanted noise picked up from the wire to the amplifier.
Plus and minus amps independently drive the right and left signals generating a high stereo effect – so you can enjoy distinct High-Resolution Audio with no crosstalk.

Discover how developments in design make the PHA-2A easier to control, more intuitive to handle and a pleasure to listen to.
Clock generators set the sample rate timing for digital-to-analog conversion. Designed to work at multiple frequencies, the precise clock ensures audio is accurately reproduced, creating the stable sound the composer intended.
A high quality volume dial regulates how voltage is delivered to the headphones. Low resistance ensures there is little signal lost, allowing you to precisely control the volume, for comfortable listening.
A gain switch lets you adjust the input signal from the source, which in turn, affects the range of volume control. Depending on how sensitive your headphones are, the balance of gain and volume comes down to personal taste.
