Cypher Labs Sustain84 Tube Headphone Amplifier

Desktop Tube Amp

Built to help you get the most out of your headphones, the Cypher Labs Sustain84 amplifier features NOS ECL84 vacuum tubes in a class-A single-ended design. The sound is full, rich, and clean at all frequencies, and the overall construction understated and intentionally simple—with a single input and output, and only two gain levels. Suitable for use with sensitive IEMs and demanding planar-magnetic cans alike, this amp is complete with a machined aluminum enclosure that looks great on your desk.

Note: This drop is limited to 5 units. At checkout, you will have the option to add cables (+ $70) which includes two mini 110mm long cables: 3.5 mm straight interconnect and 3.5mm right angle interconnect.

Along with Z11-EI48 output transformers, Nichicon electrolytic capacitors, and Cardas RCA input connectors, the Sustain84 is equipped with a specially designed switching power supply and quality fuse for ultra-low noise. You can add the included removable tube shields to block magnetic interference, and swap your ECL84 tubes for 6DX8s (sold separately) for a different audio experience.
