Senna Sound has introduced the Sunstone headphone amplifier (€3,600), which the company classifies as reference level. The newcomer features a fully discrete circuit topology operating in pure Class A. The Sunstone delivers up to 4.5 W per channel into 50 Ohms - sufficient to effortlessly drive virtually any headphones. The Sunstone suits both planar magnetic and high-impedance dynamic headphones.
The high-current, low-noise power supply supports Class A operation. According to Senna Sound, this configuration ensures stable operation with consistent output voltage and current across different volume levels.
The Sunstone is a purely analog device. Connectivity includes two unbalanced RCA inputs and one balanced XLR input - no digital inputs. The front panel features two headphone outputs: balanced and single-ended.
