The M6PRE fully balanced preamp is genuinely fully balanced; from beginning to end. Many preamps claim to be balanced but in fact are single ended preamps with balanced inputs and balanced outputs. Unlike them, the M6PRE is the real deal. Its pure Class A circuitry produces very low distortion, minimal phase shift, low noise and excellent linearity. The low impedance output stages (both single ended and full balanced) will drive any power amp through any conceivable length of cable.
The M6PRE fully balanced preamp has a wide range of inputs; two balanced inputs, phono MM/MC, four line inputs (one with HT bypass) and digital USB2. The M6PRE fully balanced preamp is the epitome of Musical Fidelity design; superlative technical performance, great flexibility, excellent build quality, beautiful visuals and excellent value for money.
