Soulution 525 Preamplifier

The Soulution 525 Preamplifier bridges your source components and power amplifiers with unwavering precision. Its dual-mono architecture keeps left and right channels completely isolated, while premium Vishay Dale resistors and high-quality relays deliver 95-step volume control without audible switching artifacts. Advanced relay-based input selection isolates unused sources, minimizing load on your equipment. A robust output stage effortlessly drives extended cable runs, supported by a switched-mode power supply with over 400,000 μF of storage capacitance for virtually unlimited dynamic headroom. The result is exceptional stereo imaging clarity and focused soundstaging, with zero coloration—the 525 simply reveals your music as intended.
