Features & Specs Line Circle

CLASS A POWER & LOW IMPEDANCE DRIVE
Revel in pure Class A power up to 30W (Delta MONO) and 12W per channel (Delta STEREO) — it’s the purest form of amplification, used to eliminate the switching distortion inherent in Class A/B designs. Enjoy low impedance drive capability offered by the overall design topology and the massive, high-quality power supply, providing effortless power delivery to control any loudspeaker.
IC TUNNEL ACTIVE COOLING
The proprietary IC Tunnel monitors heat generation and controls fan speed to maintain ideal operating temps for best performance and reliability. The IC Tunnel also allows for amplifier installation in equipment racks and cabinets where conventional passive convection cooled amps can’t go.
CUSTOM & PREMIUM PARTS
Includes 22 4-pole Mundorf® caps, a custom toroidal transformer and hand-laid multi-layer circuit boards for superior performance attributes.
FURUTECH CONNECTORS
Furutech® rhodium-plated RCA and torque-guard speaker connectors go beyond gold to provide ultimate durability and a smoother contact surface, while allowing direct-to-copper plating for greater longevity and elevated performance.
PRECISION VU METERS
Custom VU meters complement the practical purpose for reporting output power with an enticing visual aesthetic, while providing quick reassurance during the most demanding listening sessions. Also alerts you in the rare instances where the amplifier is approaching its power threshold.
NAVCOM FEET FOR REDUCED VIBRATION
Custom-made Navcom feet absorb and reduce vibrations along the signal path related to microphonics, ensuring the utmost detail and clarity in everything you hear
