A100 is an imbalanced construction with the power of 70W/8Ω, 130W/4Ω equipped with three pairs of linear RCA inputs and a pre out output.
The amplifier is designed based on the usage of topology – volume regulation – tube preamplifier SE – power amplifier using Circle Power technology.
Volume regulation implemented through the usage of a resistor lader provided by the prestigious company Khozomo. Resistors with a tolerance value of 0,1% are switched using state of the art relays which guarantees the highest possible presicion and durability unreachable for traditional potentionometers. The regulation has a remote control.
Single-stage amplifier is designed using a tube with a stable polarisation. This solution allows for the use of the lowest possible amount of passive components. This system is structured to use one lamp, a resistor and a state of the art capacitor made of solid copper foil, which directly influences the neutrality of sound and dynamism of transmission.
Circle Power power amplifier is the original development of Circle Labs. Often it is reffered to as: „the best combination of tube and transistor devices”.
This stage usues an asymmetric input stage and current steering of BJTs. This solution combines the detail and precision characteristic to asymmetric systems with the efficiency and dynamism of symmetric systems.
Power amplifiers are equipped in separate power adapters with the combined condensator capacity of 140000 µF.
