Soulution 550 Phono

The Soulution 550 Phono stands as a masterclass in analog signal retrieval, engineered to extract every nuance from vinyl's grooves. Built on dual-mono architecture with independent power supplies for each channel, it achieves exceptional channel separation while maintaining the phase coherence essential for transparent playback. The amplifier delivers a commanding 80 dB gain without compromise, handling even the most delicate moving coil cartridge outputs with remarkable linearity across an ultra-wide 1 MHz bandwidth. Dual-input flexibility allows independent configuration for moving magnet or moving coil sources, with front-panel and remote-selectable load impedance adjustment. A subsonic filter protects speakers from warped record artifacts. The output stage mirrors Soulution's acclaimed 520 Preamplifier topology, ensuring sufficient drive capability for any interconnect while preserving the tonal richness and dynamic expression that make vinyl a preferred medium for discerning listeners.
