Personal Audio Perfection 
We all know that when we listen to pure Class A amps that the sound is incredible. It is richer, fuller, smoother and the bottom end is more extended. That's why the reputation of pure Class A amplifiers remains so strong; they really are the best thing.
Musical Fidelity has a long history of making superlative headphone amplifiers. The M1 HPA pure Class A headphone amp has exactly the same sonic characteristics with headphones as our pure Class A amplifiers with loudspeakers. It sounds fantastic.
The M1 HPA pure Class A headphone amp's technical performance is outstanding. Distortion is incredibly low (less than .0005% across the band) frequency response is ruler flat. Noise ratio is outstanding. In every technical parameter the M1 pure Class A headphone amp is outstanding. The HPA's extraordinary low output impedance (below 1 ohm) means that it can drive any headphone with complete linearity and low distortion.
We believe that neutrality and complete faithfulness to the original recording is what hi-fi exists for. If you agree with that ideal then the HPA pure Class A headphone amp is for you.
“The HPA enjoys the lowest 1ohm source impedance and is capable of sustaining a full 1W into low impedance (30ohm) cans. It’s the beefiest can-driver of our group!” … “On excellent sound, facilities and value for money, the M1 HPA is a clear winner”… APRIL 2011 HI-FI NEWS
The new M1 DAC is the fruit of our 23 years experience of making top performance DACs. It has four digital inputs; coax, optical, balanced and USB.
The M1 DAC will lock on to any S/P diff signal at; 32kHz, 44.1kHz, 48kHz, 88kHz, 96kHz and 192kHz. The input sampling frequency is displayed on the front panel and it upsamples to 24-bit at 192kHz. This is genuine true upsampling.
The M1's technical performance is, pretty well, as good as any at any price. Musical Fidelity's state-of-the-art circuit design and pcb layout with the use of top quality digital components gives state-of-the-art performance.
The M1 DAC has a high quality power supply. Interestingly it has choke filtration on the mains input. This, effectively, is a mains signal conditioner which increases the performance and value of the M1 to even greater heights.
“The sound was deliciously holographic.” … “The instruments in his backing orchestra beautifully spot-lit by the M1 DAC’s sprightly and vivid demeanour. Talk about looking through the recording studio’s control room window.” … “The DAC transformed the sound” … OCTOBER 2010 HI-FI NEWS
