A200 is an imbalanced construction with a power of 100W/8Ω, 200W/4Ω equipped with a symmetric Xlr input, three pairs of Rca linear inputs amd 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 built using the dual-mono technology with seperate toroidal transfromers and power adapters with a combined condensator capacity of 200000 µF.
„With the A200, however, I heard something that happens every now and then, although not so often: it is an internally complex, rich sound with nothing missing from it, which largely repeats what I know from my own system. And that once again shows that the best designers, completely independently and in different ways, come to similar conclusions about what an audio device should sound like.”
„This is one of the best reasonably priced integrated amplifiers I know and one of the best built and best looking audio devices at any price. Bravo!”
