FEATURES
  • High-Quality Lundahl™ Transformers with Mu-Metal Shielding: Ensures extremely low noise and high-resolution sound reproduction by minimizing internal and external interference.
  • Dual Mono Design: Provides fully discrete circuitry for each channel, eliminating crosstalk and distortion for clearer, more lifelike stereo imaging.
  • Gold-Plated RCA Jacks with Teflon Insulation: Maximizes conductivity and minimizes signal degradation for high-quality signal transfer with premium interconnects.
  • Gain and Impedance Flexibility via Internal Jumpers: Compatible with most Moving Coil cartridges by allowing users to adjust gain/impedance settings without compromising aesthetics.
  • Minimal Internal Wiring with Industrial-Grade PCB: Preserves signal purity and integrity by reducing complexity in the signal path.
