What reviewers think

Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.

Product Strengths

  • Offers a stunning combination of sound and functionality, functioning as a very natural and 'do-all' cartridge
  • Reproduces both ends of the frequency spectrum with a high degree of texture, detail, and punch, including excellent bass definition
  • Creates a massive three-dimensional soundfield, delivering a more inclusive listening experience
  • Provides a natural and correct tonal balance with a slight hint of warmth, avoiding edginess or brightness
  • Offers a sound that encourages all-night listening sessions without listener fatigue

Product Considerations

  • The stylus guard, while present, does not grip the cartridge body tightly, requiring careful handling
  • The cantilever is completely exposed, increasing the risk of damage

Comparisons (according to reviewers)

  • Vs Dynavector 17D3 ruby karat, the Reference Ruby offers superior resolution and less graininess
  • Vs TechDAS TDC01 Ti, the Reference Ruby veers more toward intimacy, while the TDC01 Ti offers a greater sense of grandeur
  • Vs Lyra Atlas, the Lyra Atlas is more of a 'just the facts, sir' cartridge, while the Reference Ruby offers better tonal balance
  • Vs Clearaudio Goldfinger, the Goldfinger offers a robust, tonally saturated, and dynamic presentation, where the Reference Ruby offers better tonal balance
  • Vs Koetsu, the Reference Ruby does not over embellish as a Koetsu does to capture attention, while the Reference Ruby offers better tonal balance

Takeaway: The AVID Reference Ruby is a high-performing and balanced phono cartridge that extracts plenty of musical information from records. It is a good option for audiophiles looking for a cartridge that delivers both detail and a pleasant, natural sound.

How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

Compared to their other products

We think it's helpful to understand how this product fits into the brand's full lineup (below). To learn more about these products, visit the brand's page.

Ingenium-turntable  

  • Positioning: The entry-level model aimed at budget-conscious users.

Volvere-turntable  

  • Positioning: A mid-to-high tier option focused on greater mechanical stability and refined performance.  
  • Description: Uses an upgraded motor control and enhanced isolation measures that result in steadier operation and improved sound reproduction. In contrast to the Ingenium and Diva-II-SP models, its superior build quality and technical improvements suit buyers looking for a noticeable upgrade in performance and precision.

Acutus-reference  

  • Positioning: A high-end reference model designed for dedicated audiophile listening environments.  
  • Description: Features precision machining and an innovative motor system that markedly reduce vibration and enhance accurate tracking, setting it apart from the lower-tier products. Compared to the Ingenium, Diva-II-SP, and Volvere models, it offers advanced isolation and refined control.

Acutus-reference-mono  

  • Positioning: The flagship model with the highest level of engineering refinement in the lineup.

jewel of sound

Acquiring its name by harnessing the immense rigidity of a Ruby cantilever, musically this cartridge offers unparalleled resolution, dynamics and an openness to the sound that totally captivates.

Subtle details are a revelation of breath-taking transparency with lower frequencies formidably tight showing no loss of control and thanks to the micro ridge stylus surface noise is vanishingly low.

Design Masterpiece

By virtue of its construction, precise alignment for optimal sound reproduction is painless, the extending cantilever allowing accurate track selection and the purpose designed stylus guard offering protection when you are absent.

Exceeding our own design expectations, Reference Ruby will enrich your musical experience, abandoning the constraints of time to vividly discover your most cherished records with this design masterpiece.

Our Summary

No items found.

Product Strengths

  • Generous low-frequency transient textures, such as fingers plucking double bass strings
  • Smoothness, refinement, good timbral balance, and commendable transparency
  • Precise build quality
  • Seamless delivery, producing musical pleasure on a rich, colorful pallet

Product Considerations

  • The Titan does not include a stylus guard, which could be a problem for people with cats, children, or housekeepers
  • A particular vocal sibilant characteristic—a super-narrow, almost sweet peak—was noted
  • If hard rock is your thing—look elsewhere

Comparisons (according to reviewers)

  • Original vs test pressing of The Fantastic Expedition of Dillard & Clark—the EMT's generous presentation of bass transient textures was there too, without overhang

Takeaway: The EMT JSD Novel Titan MC cartridge uses modern materials to enhance a classic design, delivering a fast and fresh sound. With its high output and precise build, it reliably delivers satisfying musical experiences.

TDC01

Released

TechDAS
The TDC01 cartridge features a novel egg-shaped housing which was chosen because of its unchallenged structural Section Modulus properties. This unique housing made of A7075 Super Duralumin, and although difficult to machine with such extreme precision, is an ideal form factor to dissipate extraneous energy coming from the record groove. This, in turn, allows the generator system to reproduce only the clean signal of the music itself.
Check on Amazon
TechDAS is a premium turntable brand that uses rare air bearing and vacuum hold-down technologies, designed by former Micro Seiki engineer Hideaki Nishikawa. Their Air Force series turntables combine high-mass chassis with advanced air suspension systems to minimize vibrations, while their vacuum hold-down system reduces record warping for better sound quality.
Expand Details

Our Summary

No items found.

Product Strengths

  • Combines a satiny top-end sheen with an authoritarian dynamic slam and impressive transparency
  • Soundstages were deep and wide where appropriate
  • Produced transient sharpness on the bottom and in the mids
  • Tonally neutral-sounding
  • Bottom-end extension and resolution of low-level detail were high quality

Product Considerations

  • Super-refined reproduction of transients as somewhat on the polite side overall, and better suited to jazz and classical than to harder-edged rock, soul, and blues
  • Requires a very low loading value to get the most out of it, surprising considering the recommended 100-200 ohms
  • At 17gm, it is on the heavy side

Comparisons (according to reviewers)

  • The TechDAS TDC01 Ti offered transparency similar to the Kuzma CAR-60
  • The TechDAS TDC01 Ti also produced Proteus-like overall dynamic 'slam'

Takeaway: The TechDAS TDC01 Ti cartridge is a high-quality product that combines smoothness with dynamic slam, making for a refined sound. Its neutrality and detail make it a good choice for audiophiles who enjoy jazz and classical music.
