Classé Delta Stereo Power Amplifier – Classé

AMPLIFICATION
The first 12.5W of power output are 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

CLARITY
Delta STEREO delivers exceptional clarity. Every effort has been made to preserve 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 lowest noise
• 22 4-pole Mundorf® capacitors
• Custom-made Navcom® feet to absorb vibrations
• Furutech® rhodium-plated RCA and torque-guard speaker connectors

DESIGN
Delta STEREO has 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.
