Classé Delta STEREO Power Amplifier

The Classé Delta STEREO Power Amplifier distills all of Classé's innovation and knowledge into a compact high-performance stereo amplifier. In situations where dual mono amplifiers can't be accommodated, the Delta STEREO offers uncompromising performance in a single component.

Schroeder Amplification is proud to be an Authorized Classe Dealer

The first 12.5W of power output is pure Class A, and with a total of 250W per channel at its command (over 350W/Ch @ 2Ω), this compact, powerful amplifier drives loudspeakers with utmost confidence.

  • Up to 12.5W per Channel delivered in pure Class A operation
  • 250W per Channel total
  • Massive, high-quality power supply
  • Custom toroidal transformer

The Classé Delta STEREO Power Amp delivers exceptional clarity. Every effort has been made to preserve the complete separation between channels, delivering the natural, expansive sound that Classé is legendary for.

  • Hand-laid circuit boards
  • 6-layer circuit boards provide for shortened signal and power pathways with the lowest noise
  • 22 4-pole Mundorf® capacitors
  • Custom-made Navcom® feet to absorb vibrations
  • Furutech® rhodium-plated RCA and torque-guard speaker connectors

The Classe Delta STEREO Power Amp has a presence. Its capabilities are expressed through design and it looks fantastic in any room or installation. Superb material finishes and a pair of custom-designed illuminated VU meters display power output for both channels beautifully. Delta Series' design concept is to create a monument to sound. This amplifier looks every bit as capable as it sounds.
