 Ultra-Linear

Moving Coil Phono Stage/Preamp:
Reflex C

The Reflex C phono stage/preamp is our new one box solution for conventional (low) output moving coil cartridges having an output of 0.2 to 1.0 mV.

Previously only possible with our Elevator EXP/Reflex M phono stage preamp combo, the Reflex C phono stage preamp brings that missing excitement to moving coil cartridge listening, revealing the secrets hidden in your vinyl - as well as great dynamics, delicacy and just the right amount of warmth. The soundstage is simply spellbinding!

 

Graham Slee Reflex C review in Audio-Video magazine"...the Reflex C is extraordinarily quiet... absolutely invisible... The tonal harvest was rich and bountiful, with a deep sonorous bass linearly joined by a smooth and creamy midrange, and progressing to clean and open treble that lacked nothing in sparkle, but never became bright or insistent... It showed excellent attack and pace, and was never intimidated by the often lavish production... Smooth, open, detailed and unobtrusive, this is quite a superb phono stage that should hold its own against more expensive designs"

Ultra Linear!

It does what valves (tubes) did so well, but couldn't do with moving coil because of valve noise - the best sounding valve gear was ultra-linear, and we've made ultra-linear possible, with low noise, in solid state.

 

Graham Slee Reflex C review in AudioEnz online magazine"a good upgrade from the best of the currently available sub-$1,000 preamps like the Dynavector DV-75. It's good enough to pip the WhestTWO and even go head to head with the much more expensive Plinius Koru without embarrassment. A superb product, worthy of audition if you are in the market for a high end phono stage."

Michael Wong, AudioEnz (New Zealand), September 2010 (read review) (contact distributor)

 

Innovative

Imagine a tube/valve solution for moving coil phono stage pre-amplification? If only! Unfortunately tubes/valves 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 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/valve 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 out their response but obviously it has to make a 45 degree slope into a horizontal line - in doing so it introduces much phase modulation.

Plot Showing Phase Modulation Area Under Each Curve

The Reflex C phono stage preamp has more than ten times the open-loop bandwidth which means, for the same amount of negative feedback, there is an over tenfold reduction in phase modulation (note: the graph above is to a logarithmic scale). 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. Now there is!

But that's not the full story. There are lots 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 is powered by an outboard power supply. The highly refined PSU1 uni-polar power supply is the preferred option and the one reviewers chose to conduct their tests. It is available for 90-120V (for USA, Canada, Japan, Taiwan etc) or 220-240V ac mains versions. It performs pre-regulation and in conjunction with the Reflexes own onboard regulator, the combination is in fact a "super-regulator".
