The Khumar is a moving-coil phono cartridge from Engineering Beyond Imagination, or EBI Audio, built in Uttar Pradesh, India. Its appeal rests on a focused combination of specialist materials, handcraftsmanship and specifications intended to suit contemporary MC phono equipment.
At the front end of the design is a nude Shibata III stylus sourced from Japan, mounted on a 0.28 mm boron cantilever supplied by Orbray, formerly known as Namiki. Behind it is a generator based on a soft-iron magnetic core and neodymium magnets. These elements are housed in a handcrafted ebony body, giving the Khumar a distinct physical identity without abandoning the practical dimensions and mounting requirements expected of a modern pickup cartridge.
A distinctive handcrafted ebony body
The Khumar’s ebony body is its most immediately recognizable design feature. Rather than using a conventional molded shell, EBI Audio has chosen a naturally patterned hardwood and describes each body as handcrafted. That approach gives the cartridge a strong visual character, particularly on tonearms and turntables where the pickup remains clearly visible.
Material choice in a cartridge is not merely decorative because the body supports a generator that must operate while mechanically coupled to the tonearm and record groove. EBI Audio does not provide separate resonance data for the ebony housing, so specific performance claims should not be inferred. Nevertheless, the decision demonstrates that mechanical construction and finish were treated as central parts of the product rather than as secondary packaging around the generator.
The Khumar weighs 8.8 g and stands 17.8 mm high. Its weight falls within a range that many contemporary tonearms can accommodate, although owners should still confirm that their counterweight provides sufficient adjustment. The stated height is equally useful when setting arm height and vertical tracking angle, especially on turntables with adjustable tonearm pillars or interchangeable headshells.
Shibata III tracing geometry and a boron cantilever
EBI Audio specifies a nude Shibata III stylus for the Khumar. A nude stylus is formed from diamond rather than attaching a diamond tip to a separate metal shank, helping avoid the additional mass associated with a bonded construction. The Shibata profile uses an elongated groove-contact area designed to trace fine modulations while distributing contact over a larger vertical section of the groove wall than simpler stylus shapes.
That geometry can be attractive to owners of carefully maintained record collections, but it also makes accurate installation important. Cartridge alignment, azimuth, tracking force and tonearm height all deserve attention if the stylus is to meet the groove at the intended angles. The Khumar is therefore a product that rewards access to a suitable alignment protractor and a reliable stylus-force gauge, whether setup is performed by the owner or a dealer.
The stylus is attached to a 0.28 mm boron cantilever from Orbray. Boron is widely selected for premium cartridge cantilevers because it combines low mass with high stiffness, qualities relevant to transferring stylus motion into the generator. The supplied information does not establish how the Khumar compares with other cantilever implementations, but the material and named specialist supplier add useful clarity about this critical part of the assembly.
A low-impedance moving-coil generator
The Khumar’s moving-coil generator uses a soft-iron magnetic core and neodymium magnets. Its rated output is 0.3 mV at 1 kHz and a recorded velocity of 5 cm/s, while DC resistance is specified at 2 ohms. Those figures identify it as a relatively low-output source that needs an MC-compatible phono stage, a suitable head amplifier or an appropriately matched step-up transformer rather than a standard moving-magnet input on its own.
EBI Audio recommends a load resistance of at least 20 ohms and specifies load capacitance at 100 pF. The minimum resistance gives prospective owners a clear starting point when configuring an adjustable phono preamplifier. A fixed-input MC stage should be checked against these requirements, while owners using transformers will need to consider the reflected load and gain provided by the chosen turns ratio.
The 0.3 mV output is high enough to fall within the operating range of many dedicated MC stages, but adequate gain and low noise remain important. Because gain requirements depend on the phono stage, line preamplifier and overall system sensitivity, buyers should verify the complete signal chain rather than judging compatibility from output voltage alone.
Specified channel performance and setup range
The Khumar has a quoted frequency response of 20 Hz to 20 kHz within ±1 dB. Channel separation is specified at greater than 32 dB, with channel balance below 0.5 dB. On paper, these tightly stated channel figures indicate close attention to the relationship between the two generator channels, an important consideration for stereo image stability and consistent left-to-right level matching.
Recommended tracking force is 1.9 g, with an allowable range from 1.7 to 2.3 g. Starting at the recommended value is the most sensible approach, followed by confirmation that alignment, arm height and anti-skating are appropriately set. Tracking force should be measured at record level where possible, as readings can vary with the position of the measuring platform.
EBI Audio also states a 20-hour run-in period. This should be understood as the manufacturer’s setup guidance rather than a guarantee of a particular sonic change. It is nevertheless useful information for owners who intend to perform final checks after the cartridge suspension has accumulated some playing time.
System matching and the most suitable owner
The Khumar is most suitable for vinyl listeners who already have, or plan to use, a properly configurable moving-coil phono stage. Its combination of 0.3 mV output, 2-ohm DC resistance and a load recommendation of at least 20 ohms makes electrical matching relatively straightforward when the phono electronics offer adjustable gain and resistance. The cartridge should also appeal to buyers who value visible handcraftsmanship and want a design with a clear Indian manufacturing identity alongside Japanese stylus and cantilever components.
It is less naturally suited to a plug-and-play turntable fitted only with a moving-magnet phono input. The Shibata III profile also makes careful setup more consequential than it might be with a basic cartridge intended for casual installation. Buyers without suitable tools or setup experience may wish to budget for professional fitting.
Mechanical matching cannot be determined from weight alone. EBI Audio provides the cartridge’s mass and height, but the supplied specifications do not include dynamic compliance. Owners of very low- or high-mass tonearms should therefore seek additional compatibility information before purchase, particularly if they want to calculate the arm-and-cartridge resonance frequency. This limitation does not diminish the documented design, but it is an important practical consideration for system planning.
Conclusion
The EBI Audio Khumar brings together a handcrafted ebony body, a nude Shibata III stylus, an Orbray boron cantilever and a low-impedance moving-coil generator built around a soft-iron core and neodymium magnets. Its published output, loading, tracking-force and physical specifications provide a useful basis for matching it with an adjustable MC phono stage and a suitably configured tonearm. It is best suited to committed vinyl users who appreciate distinctive construction, are prepared to invest in precise cartridge alignment and have electronics capable of accommodating a 0.3 mV moving-coil source.
