The Reflex M is a phono stage preamp for moving magnet, moving iron and high-output moving coil phono cartridges in the output range 2 – 10mV. One of the great innovations that made the Era Gold V phono stage preamp miraculous and the Reflex Graham Slee‚ next generation of Stereophile “class A” recommended phono stage preamps is their extremely good open loop linearity.
Negative feedback is used in most all amplifier stages to straighten their open-loop distortion, but often lashings of negative feedback has to be used to force them into linear operation. But as tube amp enthusiasts know, lots of negative feedback doesn’t do good music.
The Reflex M phono stage preamp is highly linear before negative feedback is applied. The result is an uncanny reality which transports the listener into a very involving musical experience.
