The M6i integrated amplifier has been available for 5 years. It has established itself as a benchmark for great sound, high power and value for money. All in a compact nicely finished package. During those five years, the market has evolved; phono is resurgent and, interestingly, computer based music files have also increased in popularity. Talk about Stone Age and Space Age together! Also Musical Fidelity has been refining its circuit design and SMD PCB layout techniques.
