The KV9 Max Tonearm features a unipivot bearing design and uses a unique Kevlar tube construction, which provides lightness, stiffness, and internal damping capabilities that other materials cannot match. The tonearm incorporates oil damping, a proprietary VTA smooth adjustment mechanism, and uses a combination of premium materials including aluminum, bronze, brass, and stainless steel. The design allows for easy calibration and adjustment of attenuation, anti-skating, azimuth, and VTA which can be adjusted while listening to music.
The KV Max series represents an evolution from previous models, featuring a new, lighter and stiffer Kevlar tube, improved tube filling, and a new zirconia-based bearing. The design uses two types of bronze in place of aluminum elements, has improved VTA and azimuth adjustment accuracy, and features enhanced counterweight precision. The arm's wiring uses 24K Gold plated 6N OCC Copper.

Our summary
Product Strengths
- Unique, highly engaging, and factual rendition of the music
- Design builds on the best aspects of the KV12 tonearms, and takes performance to an even higher level by reducing weight and increasing rigidity
- New, unique bearing is made of zirconium oxide, and improved damping guarantees maximum stabilization of the tonearm with unsurpassed tracking
- Most of the aluminum elements of the arm are replaced with bronze, contributing to an increase in stability and a further reduction of resonances to an exceptional level
- Ability of unique playful interaction with the cartridge and turntable opened up a deeper interaction with the music, that is normally associated with pricier tonearms
Product Considerations
- Significantly more expensive than other models in its category
- Returning the tonearm after testing it without the hope of purchasing it will be difficult
- Even poor releases are clearly shown for their weaknesses
Comparisons (according to reviewers)
- Vs KV12: KV9 Max offers even better resolution, even better differentiation, even better insight into the smallest details and subtleties of every recording, or into even the most delicate tonal shifts and texture changes
- Vs KV12: KV12 is the clear winner when it comes to macro-dynamics
- Vs KV12: On the Dead Can Dance's Spiritchaser, what the KV9 Max did with the powerful, deep, almost subsonic electronic bass was brilliant—truly impressive, but the KV12 added even more mass and powerful slam to these deepest, lowest sounds
Takeaway: The J. Sikora KV9 MAX Zirconium is a high-performing tonearm that delivers exceptional sound quality, with great detail and clarity. This tonearm could be a worthwhile investment for those seeking the best in analog audio reproduction.

Our take on the brand
.png){kind=logo}
Phantom III is the same specification as the Phantom II, but has an updated arm wand, new internal wiring for arm wand and bearing housing. The Phantom III has exceeded our highest expectations, surpassing even the highly-rated Phantom II. And when compared to other tonearms on the market, tests and preliminary user comments have confirmed that the Phantom III is in another, altogether higher level of performance.
Compared to the original Phantom, as well as the Series II, the III has a similar outward appearance, but has important internal differences. In addition to the refined Magneglide (tm) stabilizer, new internal wiring for even better detail and improved freedom from any mechanical resistance, an upgraded pivot design for even greater dynamics, and a new titanium armwand, the III has incorporated a new pivot housing assembly.
This assembly, comprised of a constrained layer combination of brass and tungsten, provides greater energy control and damping, along with improved bearing performance. Incorporating a slightly reshaped counterweight to allow for great cartridge weight ranges and lower moment of inertia, the result is greater transparency, broader soundstaging (both side to side and front to back), with greater bass impact and extension.
Our summary
Product Strengths
- The Phantom III does not impose a consistent signature or coloration on the music, leaning towards an ideal of neutrality that allows cartridges to express their individual character more overtly
- Offers a proportionate blend of resolution, detail, bass response, soundstaging, and imaging—creating 'wholeness' in musical reproduction
- Provides stable and repeatable adjustments for fine-tuning tracking force, azimuth, overhang, zenith angle, and VTA/SRA
- Facilitates easy daily operation
Product Considerations
- The price point may be prohibitive for some
- Initial leveling may need to be checked and adjusted after a few weeks due to settling
Comparisons (according to reviewers)
- Vs Graham Engineering Phantom II Supreme: The Phantom III's bass reproduction was far more robust and controlled
Takeaway: The Graham Engineering Phantom III is a high-quality tonearm that allows for precise adjustments and stable performance, letting the true character of cartridges shine through. Its ability to trace grooves accurately and portray subtle differences in recordings makes it a worthwhile investment for serious audiophiles.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Unique bi-axis design separates horizontal and vertical movements, offering a stable platform for the cartridge and excellent tracking ability, even with warped records
- Extremely well-built, matching the high standards of SME tonearms in terms of fit and finish, with a robust and solid construction
- Cartridge swapping is made easy due to the detachable headshell and simple setup process
- Demonstrates wide cartridge compatibility, working well with both low and high compliance cartridges
- Sonically neutral and uncolored, allowing the characteristics of different cartridges to shine through
