The American brand Soundsmith has gained quite a lot of popularity as a specialist in the reconstruction of older cartridges, which it has been doing since 1972, when it was founded by Peter Ledermann just north of New York. Its offer to rebuild worn-out models to "like new" condition for about 20% of the original price is attractive. However, this is not the only thing it can do on the contrary, it also offers a very wide portfolio of phono cartridges with relatively original concepts. One such is the Zephyr MIMC Star.
At first glance, it is a slightly more distinctive, but basically classic cartridge. The body is composed of quite sharp edges, rendered in a combination of gold and bright blue, the confluence of lines in the front creates a five- pointed star. The body is thus quite robust, weighing 12.2 grams, and inside all six sides are shielded, which, according to the manufacturer, should work as a Faraday cage.
An interesting feature is the three elongated recesses on the upper part, squeezed between the holes for the installation screws. This is where you can if your turntable generates hum from the ground loop in the cartridge area place the supplied sticks, which will isolate the chassis and break the ground loop. For greater versatility or compatibility with tonearm heads, you

have a choice of either two "half" sticks with a flat top (to be installed in the side recesses) or one classic round rod (to be installed in the middle). It's quite a smart solution, although of course you have to adjust the tonearm settings slightly if you use it.
Of course, the tiny, fragile and lightweight components that create the sound itself are important for every cartridge. In the case of the Zephyr MIMC Star, it is a sapphire cantile, shaped by a laser beam so that the selected diamond tip of the Contact-Line profile adheres correctly to its end.
But most importantly, this is the name of the MIMC cartridge itself Moving Iron (for) Moving Coil (preamp). In other words, although electrically the Zephyr MIMC Star is fully compatible with MC turntable preamps (it has an output voltage of 0.4 mV and needs an optimal 58 64 dB of gain), it uses technology with stationary coils.

This idea actually means that there is (according to Soundsmith) about 5 times less mass in the whole oscillation system than with classic MC cartridges. Instead of coils, there is a tiny magnetic flux modulator oscillating here and there it has more accurate reactions thanks to its significantly lower weight, and the manufacturer also says that compared to the typical channel separation in MC solutions (20 30 dB), significantly better values of around 40 dB, simply from the principle of its operation. Fixed coils can also be significantly better dampened (with the whole system, of course), so there is less resonance and distortion.
In terms of technical parameters, the Zephyr MIMC Star is actually not an atypical cartridge in the context of its class. It offers a frequency range of 15 45,000 Hz (+/- 2 dB), the optimum pressure is around 1.8 2.2 grams, the compliance is quite low at 10 μm/mN and the minimum possible distance between channels is 25 dB (in the wide range of 50 15,000 Hz). The internal resistance is 10 ohm and the recommended load should ideally be over 470 ohm.

We had the opportunity to test the cartridge in two places. In a hurry and rather for the sake of interest, directly in the importer's studio, where they played on a Clearaudio Innovation Basic turntable with a Clearaudio Balance v2 phone, through a Pathos InPol Heritage amplifier with

Right from the first groove of "Burmester Selection Vol. 1" (2017 | InAkustik |
INAK 78041 2LP
), where we finally got to "Spore" by Kari Bremnes, it was
clear that the Zephyr MIMC Star plays differently than the vast majority of MM and MC cartridges. On the one hand, it has a less vinyl style, it has firmness and concentration on the other hand, it is not thin analytical. A character that is hard to describe, perhaps a little evocative of DS Audio's optical cartridges. In any case, the lower electronically generated octaves of the above-mentioned song were very nicely full, softly pliable rather than hard, but in accordance with the category of cartridge they were definitely already excellently defined, separated tone by tone. Despite the obvious control, the Zephyr MIMC Star doesn't suffer from an iota of dryness, but it doesn't mean a blunt characteristic (as you can see, it's really not an easy- to-grasp style). The bass was definitely bubbling with great weight, volume (maybe even a little noisy), listening seemed very easy from a subjective point of view and already a matter of course from the point of view of objective properties.

After all, Harry Belafonte's well-deserved recording "Day O" ("Calypso" | 2017 | recorded 1955 | WaxTimeRecords |
772215
) was surprisingly open
and easy to read, from its background as if the cartridge could eliminate a significant part of the noise (only your favorite god knows how it would be possible, but that's how it feels), so the voices and instruments are clear and distinct. Overall, the presentation gave such an elegant, relaxed impression, shunning technicality and excessive efforts to penetrate the depth of the content, and yet there are already a lot of details, the mids are plastic and even the softer form does not deprive them of high-end clarity.
In the recommended balance and settings, the Zephyr MIMC Star had a well-represented top range, not flashy, but certainly not dampened, as sometimes happens with analog (and how it depends on downforce, resistance and other factors). No less than the iconic cascade of tinkling in "Time Out" by The
Dave
Brubeck Quartet (2012 | recorded 1959 | Vinyl
Lovers |

) had a little kiss of analog velvet kindness draped across
the metal, but otherwise the tones and their colors were firmly realistic,
2024 06 30 TST Soundsmith Zephyr MIMC 16
sonorous, and assured. The decay of each note is smooth, you can feel that the Soundsmith cartridge does not press on the saw, but responds to the groove profile swiftly and accurately.
This quality i.e. the detachment and ability to "stay the course" also helps in the interpretation of dynamic recordings, such as the energetic "The Peppery Man" by Natalie Merchant ("
ELAC
95 Years" | 2021 | InAkustik
|
INAK 78131 2LP
). You feel the certainty with which the drive rushes into
the room and yet it is not a stiff or compulsive sound, everything is done calmly and calmly. The cartridge lets the music swing to full power from nothing with ease, the content has weight and punch and yet a certain desirable degree of velvety analogueness. It's such a cultivated liveliness.
Rutter's "Requiem" and especially "Pie Jesu" from it ("
ELAC
95 Years" | 2021
| InAkustik |
INAK 78131 2LP
) It is a beautiful work, melancholic, delicate
and mostly quiet, so to work out the fine nuances and details requires a really good distinguishing system. The Zephyr MIMC Star doesn't put any painstaking attention on details and the most fragile layer of information, yet
2024 06 30 TST Soundsmith Zephyr MIMC 14
underneath the elegantly smooth exterior of the sound, you can feel beautifully clear articulation and natural presentation without effects. The music runs like a silk thread over a surprisingly quiet and contrasting background, the legibility is organic, non-technical, but definitely adequate to the premium position of the cartridge. It is a balanced reproduction, specific, but not fierce, sober, but nevertheless full and informative. You can best see this in the fact that the choral part is not a single vocal area, but a sum of individuals that are simply understood.
The proportions of the instruments and the stage in which the instruments themselves are in Davis' "So What" ("Kind of Blue" | 2009 | recorded 1959 | Jazz Wax Records |
JWR 4534
) planted, they are quite large. The space is
seamlessly continuous, plastic, not lavishly holographic, but "normal", simply natural, and you can focus sounds in the left-right and front-to-back axis without having to make any effort. The Zephyr MIMC Star is already so good playing that the technical side of things disappears, leaving the music as such.

Also Sting's "The Hounds of Winter" from the somewhat thoughtful album "Mercury Falling" (1996 | A&M |
0731454048613
) could be described as
"cool on the level". The music flows, it does not draw attention to the string and its properties, nothing of it shines or feels missing, it is simply there harmonious, with an analogue touch, unhurried, balanced and open. It's not exactly a musical sound, but it definitely goes in that direction and skilfully reveals the musical content in a pleasing, easy-to-listen form.
More or less unusual concepts are an integral part of the offer for basically any point in the chain there are slightly special signal sources, amplifiers, speakers, not to mention cables or all sorts of accessories. And although it sometimes means "difference for difference", especially with the Soundsmith Zephyr MIMC Star "moving iron" cartridge, it is an excellently playing concept that meets the standards and expectations of its premium price tag. Very interestingly, in just a few seconds you know that the Zephyr MIMC Star simply plays differently its thoroughly neutral, frequency-balanced character provides fast dynamic response, control and very good resolution, while not forgetting to play calmly, with ease and ease. It's almost like a "mix of the best" from the world of good MM and MC cartridges. If you're in the mood for high-end vinyl without the ubiquitous delicacy of most cartridges, the Soundsmith Zephyr MIMC Star is a very fun alternative.
