Highlights Philosophy Most integrated amplifiers combine the functions of volume control, source selection and amplification in single multi-function circuit. Not so the soulution 530 Integrated amplifier. It takes the uncompromising route of separate circuits, combining a dedicated reference quality preamplifier, and a dedicated reference quality power amplifier in one housing. It is a real soulution product – truly a great amplifier.
Design The audio section of the 530 is physically separated from the power supply and digital circuits. In order to reduce interferences to a minimum, these sections are additionally shielded. The power amplifier section is executed in dual-mono layout. The left and right audio channels have their own respective identical boards to deliver a channel separation of >110dB for a three dimensional sound stage.
Amplification The amplification circuit of the 530 is based on the technology of the 710 and 700 amplifiers. At its core is an innovative voltage amplification stage that consists of linearized amplifiers operating up to a cutoff frequency of 80MHz. Current amplification is d...
Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Soulution's designs prioritize extremely high-speed circuits and substantial local negative feedback, dramatically reducing distortion and phase errors compared to traditional solid-state amplifiers.
- They utilize sophisticated switched-mode power supplies (SMPS) for exceptionally stable and clean power delivery, allowing for greater dynamic linearity and bass control.
- The brand's components, while solid-state, are often described as having a "tube-like" soundstage and imaging, with a three-dimensional bloom and a natural presentation of instrumental images.
- Soulution integrates advanced digital volume control (Leedh Processing) that preserves signal purity and micro-details, making a separate linestage preamplifier potentially unnecessary.
