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


This Audio MusiKraft patinated bronze shell is specifically designed for Denon DL-103 or 103R phono cartridges. It can be purchased nude as a starting point and customized to one's preference or as a complete kit with a preinstalled modified cartridge and wood inserts.

The Bronze (Br) Collectors Series is offered to the most discerning audiophiles who desire the ultimate in sonic performance in tandem with a supreme finish. This series has the same specifications as the gold plated Bronze (Br) version except for the added external patina finish. Adding a patina to bronze helps to accelerate by thousands of years its corrosion so as to form a protective layer with the added benefit of adding a true captivating finish for all to see.

In the Collectors Series, each cartridge shell patina is an artwork, so every piece is unique. For the works, we have opted for six (6) distinct patina finishes. Among those, each individual shell part is manually done one by one by the artisan. At the end of the process, the artwork is finally protected with a trusted Museum micro-crystalline wax polish. The patinas age over the first years and get even better with time. Before handing our pieces to the artisan for the final touch, we carefully hand polish each shell part to a mirror finish so this later helps the patina have a deeper and more detailed visual impact. Last but not least, we devote a lot of time and energy in creations that represent our labor of love. Then, for the completion of the artworks, we needed to share together a synergy with the right artisan so he faithfully communicates the meaning of our dear product. The artworks were handed to a reputable smelter (Art foundry) here in Quebec.


Bronze's sonic signature...

To best compliment the way the Denon DL-103 or the Audio MusiKraft cartridge 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.

This shell can be fully customized to your musical and/or visual preference.
