About the 750 Phono
The Soulution 750 Phono is a premium phono preamplifier designed to deliver the ultimate performance for moving coil (MC) cartridges. It features an advanced ultra-wide band (1 MHz/–3 dB) multi-stage amplifier design, achieving extremely low noise, distortion below 0.006%, and high channel separation of 60 dB at 1 kHz. The unit offers three MC inputs with fully selectable gain and terminating impedance, supporting input impedances from 10 Ω to 1000 Ω for MC cartridges. It adheres strictly to RIAA-IEC equalization standards and includes a subsonic filter (< 20 Hz) to suppress rumble from warped records. The 750 provides up to 80 dB gain (equivalent to a 10,000 times signal increase) with level and phase accuracy. Outputs include one balanced XLR and one unbalanced RCA. It requires external power via the dedicated 750 PSU or 725 preamplifier. The phono stage is noted for its neutrality, transparency, and lifelike sound reproduction, making it highly regarded among audiophiles. Dimensions are 480 × 117 × 450 mm, and it weighs approximately 17 kg.
