Audio Note M1 RIAA Phono Stage
Audio Note M1 RIAA Phono Stage
The M1RIAA is an all valve MM phono stage utilising ECC83 and ECC88 triodes. This is the second model up in the range and the first in the 'medium' sized Audio note chassis. This chassis provides great separation and screening between the power supply and the audio stages for low noise. The output stages has the ability to add some negative feedback via a switch on the rear panel, this enables it to drive lower impedance loads when required at the expense of some output level.
Naturally this can be used with MC cartridges by adding an external step up transformer.
