Introducing the incredibly amazing Metaxas & Sins headphone amplifier, the Marquis.

Not everything has to come in a square box and this is something that Kostas Metaxas firmly believes. His gorgeous creations are captivating works of art alongside immensely high grade, high specification audio products. One of his most stand out pieces is the Memento Mori, a stunning piece of CNC'd aluminium block shaped into an intricate human skull. 

Each hand made Marquis headphone amplifier is meticulously put together by Kostas and his two engineer sons. The Marquis delivers a seriously impressive frequency response to give unprecedented performance for any headphone given the privilage of being used with it.
