Classe Delta Mono Performance amplifier

The housing, which has been manufactured with great attention to detail, houses highly innovative technologies and hand-picked components that effortlessly deliver an unadulterated, noble sound.

The highlights at a glance

• Up to 35 watts (MONO) or 12.5 watts per channel (STEREO) in pure Class A operation and control with
  low impedance eliminate switching distortions at low signal levels and guarantee a sovereign
  performance with any type of speaker.
• The in-house ICTunnel™ technology for active cooling ensures an ideal operating temperature for
  maximum performance and reliability even under maximum loads.
• Special and premium components such as the 22 four-pole capacitors from Mundorf®, the custom-made
  Toroidal transformer and hand-built 4- or 6-layer printed circuit boards ensure excellent performance.
• Furutech® rhodium-plated RCA and Torque Guard speaker terminals offer greater durability and performance than gold terminals.
• Navcom® custom feet dampen vibration and counteract microphonic effects, improving overall clarity.
• Level meters provide diagnostic feedback as well as an aesthetic visual representation of the auditory and
  noticeable performance.
