The M6 Vinyl Phono Preamp was designed specifically to be a phono stage without any practical limits. Essentially, in real life, you cannot overload the input stage or find any practical limitations in the output driving capacity. Single ended or balanced. It has three inputs, each can be set for either MM/MC and exact loading. It will remember those settings.
The true point of any electronic, actually any audio component, is that you don't know it is there. You completely forget its existance. By that criteria the M6 Vinyl is almost perfect. It has no practical audible noise, it doesn't really have distortion, you cannot overload its input or output, you can load your cartridge perfectly. It exists to serve the music. To bring the artists intent, emotions and passion to your ears and heart.
