In the ever-evolving world of high-fidelity audio, where every nuance of sound matters, Serbian upstart Senna Sound has made a bold entrance with the launch of its Sunstone headphone amplifier. This reference-grade beast promises to elevate headphone listening to symphonic heights, blending raw power with exquisite tonal finesse. Founded just a few years ago by audio visionary Nemanja Cokic, Senna Sound is quickly carving out a niche among audiophiles who demand uncompromised performance from their gear.
At the heart of the Sunstone lies a fully discrete Class A circuit, a design choice that audiophiles revere for its linearity and warmth. Capable of delivering a staggering 4.5 watts per channel into 50 ohms, this amplifier ensures effortless drive for even the most demanding loads—be it power-hungry planar-magnetic flagships or finicky high-impedance dynamics. Senna Sound touts it as a device that “delivers effortless power and extraordinary tonal richness, revealing every layer of your favorite recordings with lifelike” detail, making it a dream companion for critical listening sessions.
Audiophile muscle
What sets the Sunstone apart isn’t just its muscle; it’s the thoughtful engineering that underpins it. A low-noise, high-current power supply maintains rock-solid stability across volume levels, minimizing distortion and ensuring consistent output. With a total harmonic distortion (THD) of just 0.03% at 1kHz and 1W, and a frequency response stretching from 5Hz to 100kHz (±1dB), the Sunstone captures the full spectrum of audio fidelity without apology. Connectivity is straightforward yet versatile: dual RCA inputs and a balanced XLR for sources that pack a punch, all wrapped in an input sensitivity of 0.8Vrms and 22kOhm impedance.
High-end poise
Design-wise, the Sunstone exudes high-end poise. Measuring 280 x 200 x 127mm and tipping the scales at 6.5kg, its chassis is a study in understated elegance—matte black with VU meters that nod to vintage charm while delivering modern precision. Power consumption sits at an efficient 90VA, with selectable 120/230V input for global compatibility. It’s the kind of build that feels as premium in the hand as it sounds through your cans.
Priced at €3,600, the Sunstone isn’t chasing mass-market appeal; it’s aimed squarely at enthusiasts who view headphone amplification as an art form. Availability kicks off immediately through select high-end retailers, with Senna Sound hinting at demo opportunities at upcoming audio shows. Early buzz from the hi-fi community is electric, with whispers of it being “a really stylish looking and well-specified headphone amp” that could rival established names in the category.
As headphone technology pushes boundaries—from electrostatic wonders to ultra-sensitive in-ears—the need for amplifiers that can tame them all has never been greater. Senna Sound’s Sunstone arrives not as a contender, but as a statement: Class A purity, Serbian ingenuity, and a soundstage that breathes life into every track. For those ready to transcend the ordinary, this could be the spark that ignites your next obsession.
