- The world’s first and only “Tunable” and "Customizable" phono cartridge -

For the ultimate experience, the Bronze (Br) series cartridge stands out by the lower octaves’ extended bandwidth. The soundstage foundation is more entrenched. It has a more significant footprint than other metals in upper-bass and lower-midrange tonal levels. One can feel the veracity, the syncopated rhythm and the presence of the midrange’s fundamental notes. The background is noiseless and dark which permits to restore every subtlety. Given its smoother effect on the high-medium and treble, listening with the Bronze (Br) steers the listener in a more passive, less cerebral direction, yet maintaining the right mix of details which results from it playing with grace.

Bronze's sonic signature...

To best compliment the way the Audio MusiKraft Nitro motors are designed, our latest research showed that the ideal metal shell environment to work with was a bronze alloy.

As usual, our primary objective was to provide optimal musical playback. In general, we believe bronze is quite favorable for high-performing audio component construction when introduced in strategic places. Here are two key reasons why we have chosen this mythic alloy in search of specific sonics. One, for its heavier mass, to better control the arm resonances as well as stimulate the cartridge’s moving coil suspension, and secondly, by providing to the motor the best acoustically sound structure in reference to the proper alloy composition; i.e. copper, lead and tin which are low resonant materials. These supple materials dampen the ringing transmitted back to the generator usually associated with metals and which would translate into distortion. It turns out that bronze is regarded as a durable and ageless material which last millenniums which therefore represents in some way our strong and unique recyclable feature.

In every aspect, our quest for ultimate performance has proven us right.

The new Nitro series is up to now our most advanced cartridges. This complete kit Includes an improved cartridge generator, three (3) pre-selected optimal tonewoods (chosen by us) for you to cover a large musical and sonic spectrum, and it now comes standard with the damping oil treatment, all the necessary voicing, and installation tools in an exotic wooden jewel box.

This cartridge is not limited to and can furthermore be customized to your musical and/or visual preference.
