AMPLIFICATION

The Delta MONO has been built for exceptional performance and durability – every detail is meticulously crafted. The first 35W of power is pure Class A, and with over 300W total (1,000W @ 2Ω) available, the Delta MONO can control any speaker.

• Up to 35W in pure Class A operation
• 300W total per unit
• Massive, high-quality power supply
• Custom toroidal transformer

DIFFERENCE

The Delta MONO offers ultimate clarity in everything you hear. Every detail conveys natural and commanding sound. An extensive dynamic range with minimal noise provides unparalleled fidelity to the music source.

• Handmade circuit boards
• 6-layer boards for short signal and power paths with the lowest noise
• Fully balanced output stage and balanced circuit design
• 22 4-pole Mundorf® capacitors
• Custom Navcom® feet for vibration absorption
• RCA and speaker connections by Furutech® with rhodium plating and torque protection

DESIGN

The Delta MONO continues Classé’s reputation for monumental design. The amplifier creates an immediate presence in any room or setup through its unique form and exceptional materials. The illuminated VU meter beautifully communicates output with elegance and detail.

• Harmony between minimalist design and unmatched performance
• Luxurious anodized aluminum body
• Custom, illuminated VU meters
• Excellent compatibility with other elements of the Delta family

COMPLEXITY

Thanks to the unique ICTunnel cooling technology, the Delta MONO can be stacked and placed on a shelf in a way that traditional cooled amplifiers cannot compete with. The internal temperature is continuously monitored and controlled, ensuring performance in any arrangement.

• ICTunnel temperature regulation technology
• Heats to optimal temperature in minutes
• Active sensor and adjustment of the amplifier’s optimal temperature
• Low-noise operation suitable for studio use
