The A200 is our current flagship Circle Labs integrated amplifier. Its design uses all original Circle Labs Solutions.

The P300 preamplifier is a fully balanced design from input to output. The idea behind the construction of the P300 was to build a preamplifier as neutral to the signal as possible. With the shortest possible signal path. Internal cabling length is minimal.

A stereo power amplifier with the possibility of working as well as a monoblock in a fully balanced mode. NOS Siemens triodes coupled via Supreme Silver / Gold / Oil capacitors are responsible for the voltage amplification. The power stages use the proprietary Circle Power system made for high power and high current applications.

The V1000 is a high-end phono preamplifier for MC / MM cartridges, supporting two phono cartridges independently with fully adjustable impedance (10 - 1000 Ohms) and capacitance (0-320 pF). Built with a unique Step-Up Transformer using our own technology. We are one of the few companies that created from BASIC our own SUT design. Primary winding made of Lica consisting of 25 wires (each insulated from each other, all in Silk braid. Secondary winding made of high quality copper. All this made it possible to achieve a very low resistance (0.25 Ohm / 22 Ohm) to reduce signal loss from the cartridge.
