Senna Sound Sunstone

Hand-built in Serbia by Nemanja Cokic, the Senna Sound Sunstone is a fully discrete Class A headphone amplifier that delivers 4.5 watts per channel into 50 ohms, enough authority to drive the most demanding planar magnetics with effortless control, in a chassis that pairs vintage studio aesthetics with modern engineering discipline.

Type and Technology

Desktop headphone amplifier, fully discrete Class A solid-state. Zero-feedback topology for a linear, distortion-free response across the full audio bandwidth. Meticulously regulated high-current power supply using a custom toroidal transformer and custom-tuned capacitors. Balanced XLR and dual unbalanced RCA inputs. Front-panel VU meter for real-time signal level monitoring. Available in Black, White, and Red. Hand-assembled in Serbia.

Sound Character

Authoritative, immediate, and tonally honest. The Sunstone has the visceral dynamic impact that Class A circuits deliver at their best, bass that is tactile and controlled, a midrange of genuine presence and clarity, and a treble that extends without hardness. There is no slew-rate limiting, no dynamic compression, and no clipping on transients. The noise floor is essentially unmeasurable at 0.03% THD, which makes it equally at home with sensitive IEMs on low gain and demanding planars that need the full 4.5 watts.

Build and Finish

Heavy-gauge matte chassis with tactile mechanical switching and a front-panel VU meter that gives the Sunstone a warm visual character alongside its technical precision. Each unit is hand-assembled with premium components. Available in Black, White, and Red. Voltage is selectable via rear panel switch for worldwide compatibility (120/230V).

Best For

Studio professionals and audiophiles who want a Class A amplifier with the output power to handle the full range of headphones from sensitive IEMs to the HiFiMan Susvara, in a chassis built to studio and audiophile standards equally.
