LOMC (Low Output Moving Coil) Phono Cartridges 

 

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 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.

 

Which Nitro Motor to Choose…

Audio MusiKraft offers two distinct cartridge motors: Nitro 1 and Nitro 2.

Mechanically, both motors closely resemble each other. To help distinguish them the external finish on the Nitro 2 is gold plated. The main difference stems from the Nitro 2 possessing a higher degree of copper wire purity resulting in a more faithful reproduction. Electrically; the Nitro 2  has a lower DC resistance so the recommended load is slightly different from each other and the Nitro 2  is slightly lower in output voltage than the Nitro 1.

Essentially the Nitro 1 is pleasing to listen to, it provides vivid sound which translates to a more «forefront» presentation. It offers more midrange bloom and it confers more presence than the Nitro 2.

The listener looking for a more neutral and precise reproduction will prefer the Nitro 2 version. Subjectively, this one has a flatter frequency response in its entire passband. It has slightly better and refined timbre than the Nitro 1, especially notable in the mid-range portion; thanks to the use of 6N pure copper wire. Its lower moving coil equipment mass ensures quicker transients.

 

Requirements:

The use of a Nitro cartridge requires at least three things:

  1. Medium to high mass tonearm to match these low compliance cartridges (i.e. 10g. and more).
  2. System ready for low output MC cartridges or either using a head amp or a step-up transformer (SUT).
  3. The Bronze (Br) Collectors Nitro cartridges require a tonearm able to counterbalance 21g.

 

The Cartridge Kit Includes:

  1. Either one of the two (2) distinct motors: Nitro 1 or Nitro 2;
  2. Offered in six (6) patinated artwork finish;
  3. Three (3) pre-selected tonewoods. We have chosen beeswax patinated torrefied pine, clear lacquered maple, and eco-oiled ipe as the optimal woods for you to cover a large musical and sonic spectrum;
  4. One damping oil vial, a complete tool kit and various screws for a trouble-free installation;
  5. A red stained baltic plywood exotic jewel box.
