  • A grounded Faraday Cage chassis for RFI and EMI rejection improves micro-dynamics and tonal colors and contrast.
  • Balanced components, in the push and the pull parts of the power supply, and having critical components toleranced to less than +/- 1% results in a sense of aliveness and ease in the music.
  • Special circuitry to “keep things warm” without wasting a lot of electricity means that your system is ready for you to listen to whenever you are.
