Fixed coil cartridges can sound as good or better than top Moving Coil ones. They often don't, because of poor matching with preamplifier and unwanted interaction between cartridge's inductance, cable capacitance and preamplifier loading.

Korf M³ preamplifier removes all these obstacles.
Built only for MM/MI cartridges
Before Korf Audio, most phono preamplifiers were universal. They were designed to work with all types of cartridges: Moving Coil, Moving Magnet, Strain Gauge, with transformers and head amplifiers. Jacks of all trade, and masters of none.

MM/MI cartridges have specific needs when it comes to amplification. These needs were ignored because most preamps are universal

Korf M³ preamplifier changes all that.
Sounds great right out of the box
No need to manually configure anything. No switches to switch, no knobs to turn, no guesswork, no listening 20 times to the same piece of music to decide which setting is just right.

Shall the cartridge be loaded into 47kOhm? 70? 100? 10? 100pF? 200? 400? Doesn't matter. Korf M³ technology ensures that the preamplifier is exactly matched to your cartridge at a press of a button.

First to measure
Korf M³ preamplifier measures cartridge's electrical parameters (inductance and resistance), creates an exactly matching preamplifier just for your cartridge.

Everything is done in analogue domain, the sound is never digitized.

How do other phone preamplifiers know what cartridge they are working with? They don't!
Matches your cartridge exactly
Many new phono stages have an LCD display these days. But having a display doesn't mean that it is a measuring M³ preamplifier. Other companies' preamplifiers use displays to make you choose the arcane settings — just like it used to be with switches and knobs.

Korf M³ preamplifier measures cartridge electrical parameters, using a very small test signal for less that 1 second. Then it creates an exactly matched preamplifier specifically for your cartridge! Your cartridge's data is stored in non-volatile memory and recalled every time M³ preamplifier is switched on.

Simple to operate — just one "M" for "Measure" button, then follow plain text prompts.
A great leap in sound quality
You will be surprised by what your moving magnet cartridge can do. You might be blown away, in fact. Amazed.

Transparency. Air. Shine. Resolution. Bass definition. Most likely, all of these will be improved by upgrading to an M³ preamplifier.
