About the 326

The Soulution 326 preamplifier features an ultra-linear analog circuitry using discrete components without negative feedback, delivering uncolored, natural sound with ultra-wide bandwidth up to 2 MHz (-3 dB). It has a dual mono design for channel separation, low-noise power supplies separated for analog and digital circuits, and a high-speed relay-switched volume control with 80 steps (1 dB each) that avoids clicks and preserves signal integrity. The chassis is precision-machined from solid aluminum for stability and shielding. It includes 2 balanced (XLR) and 2 unbalanced (RCA) analog inputs, with an optional phono MC input (10-1260 Ω termination impedance) and optional DAC module with digital inputs (USB, SPDIF, AES/EBU, Network). Outputs include 1 balanced (XLR) and 1 unbalanced (RCA). The preamplifier can deliver up to 200 mA peak current with very low output impedance (10 Ω balanced, 5 Ω unbalanced), enabling it to drive long cables and low impedance amplifier inputs. The optional phonocard is a two-stage active/passive design equalizing according to RIAA with 60 dB gain and high precision components. Operation is via front panel buttons and an optically controlled rotary knob. Dimensions are 430 x 350 x 142 mm, weight approx. 10 kg. The The 326 is designed and manufactured in Switzerland, starting production in Q2 2024. It is no longer considered discontinued as it is a current model.
