Product Info


The Reflex C phono stage preamp is what moving coil cartridges have been waiting for! Previously only possible with our Elevator EXP and Reflex M combo, the Reflex C brings that missing excitement to moving coil cartridge listening, revealing layers of performance buried in your vinyl - as well as great dynamics, delicacy and just the right amount of temperature.

Innovative Ultra-Linear Solid State
The best sounding valve (tube) gear is ultra-linear. Graham Slee has made ultra-linear possible in solid state (read on below for explanation). It does what tubes do so well, but couldn't achieve with moving coil because of tube noise.

Imagine a tube solution for moving coil phono stage pre-amplification? If only! Unfortunately tubes don't have the open-loop gain and are too noisy to do moving coil pre-amplification unless you also use a step-up transformer (or even better, our Graham Slee Elevator EXP flat gain step-up stage). But now, with the Reflex C phono stage preamp you can get the sound you're searching for - yes, that illusive tube linearity from solid state!

But how? Conventional solid state moving coil phono stage preamps have poor open-loop bandwidth which means their open-loop response is only a few tens of hertz (see plot). Negative feedback straightens their response out but obviously it has to make a 45 degree slope into a horizontal line - in doing so it introduces much phase modulation.

The Reflex C phono stage preamp has more than ten times (10X) the open-loop bandwidth which means, for the same amount of negative feedback there is an over tenfold reduction in phase modulation. It has been known for several years that tubes/valves have this property (albeit at much lower gain) but there wasn't the technology available to replicate it in solid state, and at the required gain.

There are many more refinements designed to take the Reflex C phono stage preamp's own influences out of the music's way, including excellent radio frequency rejection at input, power supply input and output, as well as selection from the best branded components available that gel to make the most precise sound stage delivering an unbeatable moving coil musical experience.

Power Supply
The Reflex C phono preamp comes with the PSU1 linear power supply incuded and sounds best with it. It offers more dynamic reproduction and a more visceral musical foundation.
