Musical Fidelity's Antony Michaelson is a huge fan of headphones and regularly uses them at home for critical/recreational listening. Hence, the company's legacy of high-quality headphone amplifiers in its product line up. The Musical Fidelity M1 HPA is totally straightforward. It has sockets for two sets of headphones, plus inputs for line/ USB and a volume control. There's also an output via RCA phono sockets, enabling the device to be used as a preamp – but more on this later.
