- [Hi-Fi Tone Control for Perfect Sound] Unlike most purist preamps, the C1 features a high-fidelity Treble and Bass adjustment circuit. This allows you to correct source limitations, enhance details at low volume, and perfectly "polish" the sound of both tube and solid-state power amplifiers.
- [Ultra-Low Noise Floor] Engineered for a dead-silent background. The advanced circuit achieves an extremely low noise floor, measuring just 0.08mV at minimum volume and 0.7mV at maximum volume. This results in a high signal-to-noise ratio of up to 96dB, allowing every micro-detail in the music to emerge.
- [Audiophile-Grade Components] Built on a 2u immersion gold PCB, this preamp features true 5U4C tube rectification and a linear regulated supply with a 10H choke and CLC filter. The signal path uses premium imported Rel-cap coupling capacitors, tone capacitors, electrolytic capacitors, and gold-plated ceramic tube sockets.
- [Versatile Connectivity & Tube Options] Equipped with 4 sets of RCA inputs switched by relays and 2 sets of RCA outputs. The Standard version includes four 6H8C tubes, while the Upgrade version comes with four premium Psvane CV181-SE tubes. A Balanced Version with XLR inputs/outputs is also available as an option.
- [Classic Vintage Design] Features a robust 43cm standard-size chassis with a thick aluminum alloy front panel. The two large, responsive VU meters provide a classic look, while the external tube design allows for easy tube rolling and replacement. The unit has a solid net weight of 12kg (26.5 lbs).
