About the Convergent Audio SL-1 Ultimate
The Convergent Audio SL-1 Ultimate is the result of decades of refinement to the original SL-1, introduced in 1985. It is designed to eliminate electronic artifacts and allow superior audio systems to reach their full potential. The SL-1 Ultimate features a robust steel chassis with internal damping compound for resonance control, high-quality Cardas RCA jacks, and a stepped attenuator volume control manufactured in-house. It uses five tubes: a matched pair of 6922s, a single 6922, and a matched pair of 12AX7s. The preamp is single-ended only, with no balanced outputs. The balance control uses resistor-based 0.5dB steps over a 5dB range, and the unit includes a mute switch. The SL-1 Ultimate is highly regarded for its open, dynamic, and quiet sound, making it a reference choice for discerning audiophiles.
