Aesthetix IO Mk2 Superior is the basic version of their top line offering. The basis for reaching to the stars in various configurations to meet individual needs.

Io is an all-tube phono stage suitable for the most demanding cartridges, including low-output moving coils. It is in the Jupiter Series, sharing common design characteristics with the Callisto. It has won numerous awards, receiving worldwide acclaim for its superior sound quality.

  • High gain / low noise capable of handling low output moving coils
  • Zero global feedback
  • 80dB maximum gain, internally selectable down to 56dB
  • Flexible user selectable loading on the back panel from 47Kohms down to 10ohms
  • All tube amplification and output (16 tubes total)
  • Separate vacuum tube regulated power supply utilizing 8 tubes
  • Two sets of XLR and two sets of RCA outputs per channel
  • Input can be either RCA or XLR
  • Optional: Innovative and unique mechanically switched discrete resistor volume control with 46 positions using Roederstein resistors, one for each channel

Io is available in three versions: Mk II, Signature and Eclipse. The Mk II version uses high-grade Rel-Cap polypropylene coupling capacitors. The Signature version uses exotic and expensive coupling capacitors and other critical parts to bring the performance to a higher level. Eclipse is the ultimate realization of the true capabilities of the io, incorporating constrained-layer damped machined aluminum panels and Peter Moncrief's Stealth Capacitors. All versions of Io can be factory upgraded to Signature or Eclipse.
