Phono Preamplifier Soulution 757 Deemphasis Preamplifier
Description
The soulution 757 redefines the boundaries of analog playback, setting unprecedented global benchmarks as a reference deemphasis preamplifier for all analog sources. Engineered to interface flawlessly with MM/MC cartridges, tape heads, and optical cartridges, its revolutionary input stage utilizes parallelized instrumentation amplifiers to deliver a staggering noise density below -170 dBV. For vinyl enthusiasts, it features a comprehensive suite of historical phono curves (RIAA, Decca, Columbia, London, Teldec, NARTB) executed with flawless accuracy (±0.05 dB from 20 Hz to 200 kHz), alongside a dedicated wideband transimpedance input designed specifically for DS Audio optical cartridges. Reel-to-reel connoisseurs will appreciate the tape head input with an active calibration network supporting IEC and NAB equalization. System gain is managed via an 80-step, dual-path relay network using high-precision metal foil resistors for pure, click-free adjustments. Driven by a powerful Class-A output stage with a 20 MHz bandwidth and backed by a dual-mono distributed local power supply, the soulution 727 guarantees a breathtakingly holographic, lifelike, and profoundly musical analog experience.

Soulution Audio: Swiss Precision, Uncompromising Speed, and Absolute Transparency
Swiss manufacturer Soulution Audio represents the pinnacle of ultra-high-end audio engineering. The brand was founded in Dulliken, Switzerland, by Cyrill Hammer and Roland Manz, managing directors of Spemot—a renowned Swiss precision engineering firm specialized in electric motors and custom electronics. Driven by a passion for music and a desire to transcend the limitations of existing reference equipment, they set out to create audio electronics characterized by extreme speed, surgical accuracy, infinite dynamic scaling, and zero tonal coloration.
Leveraging Swiss manufacturing expertise alongside an elite team of engineers, Soulution officially launched its reference line of amplifiers, preamplifiers, and digital sources around 2005–2006. Soulution components incorporate ultra-fast circuit topologies, massive power supplies, and uncompromising current control, allowing loudspeakers to reveal the subtle micro-details of a recording with effortless naturalness. Hand-built in Switzerland to exacting standards, Soulution products are designed for audiophiles who demand absolute sonic truth, uncompromised signal purity, and sovereign speaker control. At Dream Audio, we proudly feature Soulution Audio as an benchmark of Swiss acoustic perfection and ultimate fidelity.
