About the 331
The Soulution 331 is a 3-series integrated amplifier that combines a dedicated preamplifier and power amplifier in one chassis, with optional DAC and MC phono modules. It uses a three-stage current amplification design, relay-switched volume control, and a switched-mode power supply architecture aimed at very low phase shift and high power stability. The 331 replaced the 330 in Soulution’s lineup and entered production in 2024.
