About the 710

The Soulution 710 is a solid-state, two-channel power amplifier designed for exceptional speed, precision, and power. It delivers 120 watts per channel into 8 ohms, 240 watts into 4 ohms, and 480 watts into 2 ohms, with a maximum peak current of 60 amps per channel. The amplifier features an ultra-wide frequency response from DC to 1 MHz (-3 dB), an extremely low total harmonic distortion plus noise (THD+N) of less than 0.0007% at 50 watts into 8 ohms, and a damping factor greater than 10,000 at 100 Hz. It has a voltage gain of +26 dB, input impedances of 4.8 kΩ (XLR) and 10 kΩ (RCA), and a signal-to-noise ratio of 107 dB. The design emphasizes short signal paths, dual-mono architecture, and uses 14 temperature-controlled power transistors per channel mounted on a thick copper bus bar. The power supply includes two 1000 VA toroidal transformers and nearly 250,000 µF of capacitance for stable and linear operation. The chassis is made of black or silver anodized aluminum, measuring 21" (535 mm) wide, 10.9" (277 mm) high, and 18.7" (480 mm) deep, weighing approximately 80 kg (176 lbs). The amplifier is noted for its transparency, transient speed, and musical engagement, with a price around . It is manufactured by Soulution, Spemot AG in Switzerland.
