Circle Labs Audio Circle Labs AS100 AS 100 High End Stereo Vollverstärker aus 2026

Circle Labs Audio, a boutique Polish hi-fi brand from Krakow, traces its roots to 2007 when engineer Krzysztof Wilczyński founded the company after years of designing tube amplifiers as a hobby. He partnered with designer and marketer Krzysztof Lichoń, blending Wilczyński's audio expertise with Lichoń's distinctive aesthetic vision. Though the name emerged around that time, the brand gained traction only in recent years through rigorous in-house testing and real-world audiophile feedback.

The company specializes in hybrid amplifiers that fuse tube input stages for warmth with solid-state output for power and reliability. Key offerings include the flagship A200 integrated amplifier, now joined by the P300 preamplifier and M200 monoblock power amp—capable of stereo or bridged mono operation. Earlier models like the obsolete A100 laid the groundwork, emphasizing precise sound reproduction over mass production.

Positioned as a niche high-end contender, Circle Labs commands respect among discerning buyers for its innovative R&D, elegant industrial design, and musical purity. It appeals to those seeking integrated solutions that rival established names without compromising on detail or dynamics, carving a growing international presence in the competitive hi-fi landscape.
