Classe Power Amplifier Delta Stereo

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. It’s 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 has capable as it sounds.
