Power Amplifier Soulution 717 Power Amplifier
Description
The soulution 717 represents the pinnacle of Swiss audio engineering, defining a new global benchmark for power amplification. This reference power amplifier is engineered to drive any loudspeaker on the planet with absolute authority, shattering previous limitations in noise, phase coherence, common-mode rejection, and distortion. Designed as a strict dual-mono masterpiece, the 717 features entirely separated PCBs for the left and right channels, achieving an extraordinary channel separation of over 120 dB. Its innovative input stage utilizes parallelized instrumentation amplifiers with a 20 MHz bandwidth to deliver an astonishing common-mode rejection ratio (CMRR >105 dB) without inducing noise. The ultra-linear voltage stage operates with a monumental loop gain of over 120 dB and a 2 MHz bandwidth, guaranteeing unmatched phase coherence. In the current stage, 16 power transistors per channel work in Class AB, managed by a smart bias circuit that monitors each transistor in real-time. Supported by four ultra-high peak-power switched-mode power supplies delivering over 400 Amps of impulse current, the soulution 717 seamlessly fuses delicate micro-dynamics with staggering raw power.

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.
