Key Specifications and Features:
The unit is available in two versions: Classic (black box) and Deluxe (chrome and gold finish). 

  • Valve Complement: Typically uses three double triode valves, often cited as two ECC82 (12AU7) and one ECC83 (12AX7). Some sources also reference ECC88 variants.
  • Inputs: Features 6 total inputs (5 line-level RCA inputs plus 1 genuine tape monitoring circuit).
  • Outputs: The standard version has one main RCA output and one tape output. The Deluxe version adds extra outputs to facilitate bi-amping systems.
  • Power Supply: Employs a high-quality toroidal transformer with a double DC power supply to provide pure current for both heater and anode voltages, minimizing AC ripple.
  • Circuitry: Minimalist “de Paravicini” architecture designed to reduce sonic degradation. 
Technical and Sonic Characteristics
  • Sound Profile: Users and reviewers from Audiogon and Technology Factory describe the sound as smooth, detailed, and “musical,” with a particularly strong presentation of image dimensionality and middle frequencies.
  • Measured Performance: According to detailed measurements from Audio Science Review, the unit is “distortion limited” by design, with a dominant 2nd harmonic that adds traditional “tube warmth”. However, it has been noted for having relatively poor channel separation compared to modern solid-state equivalents.
  • Durability: The valves are designed for a minimum life of five years of continuous operation
