Dynaudio Arbiter Amps, Pre-Amp and power Conditioner in Mint Conditions

The Arbiter project was something that Dynaudio started ONLY to help with development of their speaker component and loudspeaker designs, in such that the Arbiter does not have any character of its own……..the sound is completely neutral and only amplifying the original source. They are truly amazing, cost-no-object designs, and are no longer in production which retailed at $300,000 for the package (USA: $120,000 for each amp and $80,000 for the preamp). Dynaudio produced and sold 30 pairs of the amps and 40 preamps Dynaudio Arbiter Amp Effective Output: 620W (8Ω), 1072W (4Ω), 1670W (2Ω) Frequency response: 0.3Hz-300kHz (-3dB) THD levels: less than 0.005% (8Ω) S / N ratio: 103dB or more Input Impedance: 2000Ω Input Sensivity 2,25V, 6,75V Damping Factor: 1000 or more (Output 1), 40 or more (output 2) Power consumption: 120W, 2000W (Max) Size (WHD): 27.5 × 80 × 67cm Weight: 140kg each Output level (maximum): 17V (Balanced), 8.5V (unbalanced) Frequency: 5Hz-100kHz (± 0.1dB) THD level (maximum output): less than 0.005% S / N ratio: 128dB or more (line), 78dB or more (Phono) Crosstalk:-127dB (100Hz),-110dB (1kHz),-92dB (10kHz) Pre-Amp Input impedance: 2000Ω (Balanced), 11000Ω (unbalanced) 14-47000Ω (Phono) Output impedance: 100Ω (balanced), 50Ω (unbalanced) Consumption power: 25W, 250W (max) Size (WHD): 27.5x27.5x47.5cm Weight: 80kg The amps S/N are #025 and the pre-amp is #017. “The units are kept in excellent condition with no scratches or marks , I have the original remote control, owners manual, box and packing materials.
