Предусилители — Soulution Audio 525 preamplifier

The 525 preamplifier is a flagship preamplifier from Soulution Audio, built with an exceptionally wide rated bandwidth and extremely low distortion. This model represents Soulution Audio's most ambitious preamplifier engineering, incorporating measured figures that place it among the most transparent preamplifiers available at any price.

Position in line

It sits alongside the 727 and 326 preamplifier in Soulution Audio's preamplifier range. This positioning alongside the 727 and 326 suggests Soulution Audio offers a small, carefully graduated family of preamplifiers, each likely differentiated by connectivity and specific chassis scale.

Key specs that matter

Two balanced and two single-ended inputs are provided, with one balanced and one single-ended output. Input impedance is an exceptionally high 820 kOhm balanced. Rated bandwidth is an extraordinary 0 Hz to 2 MHz. Signal-to-noise is 120 dB with distortion under 0.00009%. At 442 x 143 x 448 mm and 20 kg it is a substantial chassis.

Sound and use context

Expect an exceptionally transparent, wide-bandwidth presentation with the extremely high input impedance minimising loading effects on source components - a reference-level performer reflecting Soulution Audio's characteristic uncompromising Swiss engineering.

Pairing

Both balanced and single-ended outputs allow it to partner with either type of power amplifier without adapters, giving genuine flexibility for a mixed-brand system.

Alternatives

The 727 and 326 preamplifier sit alongside this model in Soulution Audio's preamplifier range, worth comparing directly on connectivity and specific chassis scale with a specialist dealer before choosing between these closely positioned flagship options. Given the considerable price and ambition this flagship preamplifier represents, a dealer demonstration alongside a matching Soulution Audio power amplifier is strongly worthwhile before committing, since the brand engineering philosophy likely shines most clearly in a fully matched system. Soulution Audio relatively small dealer network worldwide means sourcing a specialist is well worth the extra research effort. Overall this remains an uncompromising flagship choice reflecting Soulution Audio absolute best engineering. A dealer visit remains the simplest way to compare this model against both the 727 and 326 preamplifier. Cable and stand choices matter far less here than the basic power amplifier pairing already covered.
