Senna Sound Sunstone: A Premium Class A Headphone Amplifier with 4.5W Power

Senna Sound, an audio manufacturer based in Serbia, has unveiled the Sunstone, a headphone amplifier that boasts reference-quality performance and a fully discrete Class A architecture. This amplifier is capable of delivering an impressive maximum output of 4.5 watts per channel into a 50-ohm load, enabling it to effortlessly drive almost any headphone available today. The Sunstone is offered in three distinct colors, catering to different aesthetic preferences. Its Class A amplification circuit is powered by a low-noise, high-current power supply, ensuring stable performance and consistent output across all volume levels. Notably, the Sunstone is an all-analog device, featuring two RCA inputs and a single XLR input, but it does not include any digital inputs.

On the front panel, users will find two headphone jacks: one balanced and one unbalanced. The amplifier is designed with a frequency response range of 5 Hz to 100 kHz, and it maintains a low total harmonic distortion (THD) of only 0.03 percent, factors that contribute to its ability to reproduce sound accurately and with minimal distortion throughout the audible spectrum. With its robust power output, the Sunstone is compatible with both magnetostatic and high-impedance dynamic headphones, allowing it to seamlessly integrate with a variety of headphone models and audio system setups. The price for the Sunstone is set at €3,600.
