I pretty concur with the positive views on the M1 DAC.
I recently purchased the Musical Fidelity M1 Headphone amp partnered with the DAC.
Most of my listening has been using Grado GS1000i listening to ipod Classic, WAV or Apple lossless files,
sent via Wadia 170 digital dock to the Musical Fidelity DAC and then to the M1 HPA.
This is without debt my best headphone listening experience so far, the whole set up, including cables, cost
me around 3,000 pounds but it compares very well with my Hi -Fi set up which cost me nearer 20K.
I am a Musical Fidelity fan and have been using them on and off for 20 years now. My only
real complaint would be they replace products too quickly. There seems to be a new product
I would recommend the DAC wholeheartedly.
