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.
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.
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.
