Product Overview & Specifications
The Aavik C-880 is the flagship reference control preamplifier from Audio Group Denmark, designed to serve as an uncompromising, ultra-silent control center for state-of-the-art audio systems. Created through the joint vision of Gryphon Audio founder Flemming Erik Rasmussen and Michael Børresen, the C-880 features an inverted amplifier topology with virtual ground, a switchless LDR (Light Dependent Resistor) volume control, and an all-analog crossover and room correction network.
Housed in a solid copper enclosure with a titanium-laminated sandwich bottom plate, the cabinet virtually eliminates magnetic hysteresis, inductance, and mechanical resonance. The preamplifier is powered by four 500W sine-wave resonant mode power supplies and is outfitted with Audio Group Denmark’s most extensive noise-reduction matrix—featuring 663 active square PCB Tesla coils, 314 active Tesla coils, 2 active zirconium anti-aerial coils, and 36 3rd-generation analog dither circuits—delivering a near-zero noise floor and breathtaking dynamic scale.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Flagship Collaborative Design: Jointly created by Flemming Erik Rasmussen and Michael Børresen, merging striking industrial aesthetics with state-of-the-art analog circuit topology.
- Solid Copper Enclosure & Sandwich Chassis: Heavyweight solid copper body with a copper/laminate/titanium bottom plate suppresses hysteresis, lowers output impedance, and dampens micro-vibrations.
- Switchless LDR Volume & Input Board: Light-Dependent Resistor optical attenuator attenuates signal without mechanical switches or relays, preserving delicate micro-details and tonal authenticity.
- All-Analog Active Crossover & Room Correction: Zero-latency analog dual-slope filters eliminate pressure-wave "room boom" and enable precise 2.1 subwoofer integration without DSP latency.
- Resonant Mode Power Supplies: Powered by four 500W power-factor-corrected sine-wave power supplies capable of peak currents in excess of 80A with ultra-low voltage ripple.
- Comprehensive Ansuz Active Noise Cancellation: Outfitted with 663 active square PCB Tesla coils and 314 active Tesla coils to actively eliminate power supply noise and voltage spikes.
- 36 Active Analog Dither Circuits & Zirconium Resonance: 3rd-generation radar-derived anti-phase dither technology paired with zirconium anti-aerial coils for unprecedented background silence and spatial imaging.
