711 Amplifier
Best high fidelity amplifier for discerning audiophiles.
The Soulution Audio 711 is a rare, high-end stereo amplifier designed for unparalleled musical precision. It significantly outperforms its predecessor, offering enhanced stability, speed, and a natural musical experience. Featuring a cutting-edge switched-mode power supply, it ensures exceptional stability and precise sound reproduction. This amplifier boasts impressive power capabilities, delivering 150W into 8Ω, 300W into 4Ω, and 600W into 2Ω, with pulse power exceeding 6,000W per channel, making it suitable for demanding, low-efficiency speakers. Its advanced circuit design combines an ultra-wide bandwidth with high current capability for superior precision and velocity. The 711 also features remarkably low distortion and noise levels, with THD+N below 0.001% and a signal-to-noise ratio of 108 dB. Connectivity includes balanced (XLR) and unbalanced (RCA) inputs, and it is housed in a robust chassis with high-quality gold-plated copper output terminals.

Know before you buy
The 711 is built on an ultra-fast, wide-bandwidth circuit design that prioritizes signal purity and transient response. Unlike many amplifiers that rely on heavy global feedback, the 711 uses a proprietary design to maintain absolute control over the speaker drivers without coloring the sound.
While the 711 is compatible with most high-quality preamplifiers, it is designed to be exceptionally transparent. To fully realize its potential, pair it with a preamplifier that offers a similarly low noise floor and high-resolution output, such as the matching soulution 725.
The 711 features an incredibly robust power supply and high current capability, allowing it to maintain stable performance even with speakers that have complex impedance dips. It is designed to act as a 'straight wire with gain,' providing effortless power that keeps your speakers under tight control at any volume level.
The 711 operates in a refined Class A mode for the majority of its output range. This ensures the linear, distortion-free performance associated with Class A designs while maintaining the efficiency and power reserves needed for demanding musical passages.
The 711 is a substantial piece of equipment that generates heat during operation. You should place it on a sturdy, vibration-dampened surface with at least six inches of clearance on all sides to ensure proper airflow and thermal management.
Yes, the 711 includes a standby mode for convenience. However, like most high-performance audio components, the internal circuits reach their sonic peak after they have been powered on and stabilized for at least 30 to 60 minutes.
