Sugden Masterclass HA-4 Headphone Amplifier
The HA-4 is not only a state of the art class A headphone amplifier, it can also be used as a compact high-end pre-amplifier.
The design shares many similarities to Sugden’s top of the range Sapphire DAP-800 and will drive any dynamic headphone. Featuring Sugden VCV circuit and coupled to a pure class A zero feedback mosfet output stage.
The HA-4 is unconditionally load stable with a discrete constant voltage series power supply and a high input impedance ensures absolute minimal loss of signal with perfect current gain.
Standard finish options are either black or silver – please contact us directly for Sugden’s custom colour options service!
