One of the great innovations that made the Era Gold V phono stage preamp miraculous and the Reflex our next generation of Stereophile "class A" recommended phono stage preamps is their ultra open loop linearity.
Just like tubes (valves) the Reflex M does with solid-state a number of ultra-linear techniques that makes music sound so incredibly live!
Negative feedback is used in most all amplifier stages to straighten their open-loop distortion, but 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.
