We’ve really done a good job! We were all a bit skeptical about the ability of disposal of our heat-sink. We had been thinking of it for a while, but we had never actually tried. Then, one day Filippo, our technician, called us and said: “Incredible!” And it never goes into protection!, and I still haven’t even attached the 2nd heat sink (the extruded aluminum chassis)… “Well”- I answered – “And now make it produce an audiophile sound!” And Filippo did. When we started with the design of AS, everybody had something to say for the “model amplifier”, firing all the “usual” key points:


  • High quality sound.
  • Maximum reliability for the most difficult installations.
  • Ability to drive loads up to 1Ohm stereo.
  • Compact dimensions.
  • Top adjustment, intuitive and easily accessible.
  • Connections completely covered and isolated by thermoplastic parts resistant to high temperature (those of the supply are huge).
  • Hidden mounting points for a neat installation.
  • Simple and intuitive design.
  • 100% made in Italy
