Nitro series cartridges

Why the name Nitro? Well for starters it’s related to the improved motors and the shell shape. Secondly, we wanted to add some “Oomph” to better describe what we were seeking and what we were hearing. These are a few resulting key attributes that best reflect the series name: lively, spontaneous, impactful, realistic, tone right, vibrant, musical, and dare we say, downright impressive.

Since the beginning in 2017 we have demonstrated through many excellent reviews that our design is very unique and figures among the best ranking. Always striving to go further, today with the Nitro Series we are offering what we believe is the best of the best at very competitive pricing.

The new Nitro series is up to now our most advanced cartridges. The complete kits are offered in two (2) motor versions (Nitro 1 and Nitro 2) and four (4) alloy shells to choose from. Each kit includes our improved 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 a newly designed jewel box.

Beyond the stylus and the cantilever quality, the magnetic field is one of the fundamental properties of the physical cartridge environment. While searching for improvement, our experience shows that upgrading to exotic cantilevers and diamonds does not necessarily emerge to winning results; we were losing some of the cartridge’s intrinsic virtues to faithfully reproduce musicality. We further shifted our research to investigate the magnetic field which we believe is overlooked.  To attain the best sound, our improved motors use an amalgam magnet core composition, and we precisely control how the array interacts within the generator’s critical gap. Most of our studies are based on rigorous trial and error and A/B listening tests.


Considering their versatility, their modular power, and fully customizable aspect, these unique cartridges are a leap in the industry as now cartridge voicing and its optimization are attainable on the field.  All cartridges come in a versatile kit form that can be fully customized to your musical and/or visual preference. We supply standard and customized parts to original MusiKraft owners through our Fidelity Program (page soon to come).

Using our cartridge requires at least three things:

  1. Medium to high mass tonearm (i.e. 10g and more) to match our low compliance cartridges suspension.
  2. System ready for low output MC cartridges or either using a head amp or a step-up transformer (SUT).
  3. Tonearm able to counter-balance 11 to 21g depending on the alloy series one chooses.

Note: Depending on your tonearm setup, this cartridge may require a slight modification as of height or VTA compensation. This cartridge mesures 17.7mm from stylus tip to the cartridge top.
