Description
- Innovative Input Stage: Provides exceptional common mode rejection without introducing noise.
- Precise Volume Control: Relay-switched, high precision resistors form an 80-step control, with a secondary path for click/pop-free adjustments.
- Optional Phono-Preamplifier: Optimised for low noise and high common mode rejection, with adjustable gain and impedance.
- High-Performance Output Stage: Class-A operation optimised for speed, precision, and high peak currents, capable of driving long cables.
- Distributed Local Power Supply: Ensures minimal noise levels and efficient operation.
