Class A valve operation and removing the need for a phase splitter, which introduces unnecessary crossover distortion. The Audio Note amplifier range does not make use of any kind of feedback. As a result, they were neither designed for vanishingly small harmonic or low intermodulation distortions, but instead for minimal non-harmonic and time base anomalies.
The phono input is suitable for connection to a turntable with a moving magnet (MM) type cartridge. Turntables with moving coil (MC) type cartridges will require a step- up transformer between the turntable and the pre-amplifier; Audio Note produce some of the best step-up transformers available.

Using the M9 Phono Once all the connections are completed and checked, make sure all power amplifiers are off and flip the mains rocker switch located on the back panel of the PSU to the 'on' position. The M9 Phono is a vacuum tube design and therefore requires about 45 seconds warm-up time.
Warranty and Servicing Audio Note warrants that this product will be free from defects in materials and workmanship for one year from the original date of purchase from an appointed Audio Note dealer. The valves are warranted for three months.
