AMPLIFICATION

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

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

CLARITY

The Delta STEREO offers exceptional clarity. Every effort has been made to maintain full channel separation, providing the natural and extensive sound that is legendary for Classé.

• Handmade circuit boards
• 6-layer circuit boards providing shortened signal and power paths with the lowest noise
• 22 4-pole Mundorf® capacitors
• Specially designed Navcom® feet for vibration absorption
• Furutech® RCA and speaker connectors with rhodium plating

DESIGN

The Delta STEREO has presence. Its capabilities are expressed through its design and it looks fantastic in any room or installation. Beautiful material surfaces and a pair of custom illuminated VU meters elegantly display the output power for both channels.

The design concept of the Delta Series is to create a monument to sound. This amplifier looks as capable as it sounds.
