Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- AVID's design philosophy revolves around minimizing unwanted noise and vibrations by using rigid, heavily damped, proprietary materials for the body and yokes of their cartridges, turntables, and tonearms.
- Neutrality is a recurring theme, with Avid products aiming for an "utterly neutral" sonic signature to provide a blank canvas for other components and recordings to shine.
- AVID turntables and cartridges are designed to be relatively insensitive to their environment, not requiring exotic racks or dedicated supports, suggesting their designs handle vibrations effectively.
Select products
Ingenium-turntable
- Positioning: The entry-level model aimed at budget-conscious users.
- Description: Offers a reliable belt drive mechanism and basic isolation features that help deliver clear sound in smaller rooms. In comparison to the other models, it provides essential performance without advanced engineering details for those who need simple functionality at a lower cost.
Diva-II-SP-turntable
- Positioning: A mid-range model that builds on the entry-level design with enhanced mechanical features.
- Description: Introduces an improved suspension system and refined tonearm design that help boost tracking precision and stability over the Ingenium. Compared to other products in the lineup, it offers a balanced step up in engineering for medium-sized setups.
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.
- Description: Features a bespoke mono-block design that significantly improves channel separation and minimizes interference, distinguishing it from all other models. Compared to the Acutus-reference and the rest of the range, it provides the most sophisticated circuitry and tonearm system.

Our Summary
Product Strengths
- Exceptional sound quality right away that continues to improve
- Capable of uncompressed dynamics at both loud and soft volumes, micro and macro, and doesn't harden or distort when playing loud
- Can handle big scale, orchestral, beautiful music to really raw, crazy metal music, all played convincingly at loud and soft levels
- New details are revealed without being hyper-analytical, sterile, or harsh
- Built like military materiel
Product Considerations
- Each monoblock weighs 145kg, so owners will welcome assistance when receiving it
- Inputs are on balanced XLR only, while the solid copper speaker terminals are designed for spade lugs, not 4mm bananas
- The Breguet watch dial-inspired meter's 'time-keeping' is less accurate
Takeaway: The D'Agostino Relentless 800 reproduces a wide range of music genres with detail and dynamics, offering an immersive and enjoyable listening experience. It brings out the best in music.

Our take on the brand
Our Summary
Product Strengths
- Delivers 800W of class-A power regardless of the speaker load
- Features XD technology that lowers output impedance, resulting in more control over the speaker drivers and improved soundstage depth
- Employs Sym-Max technology to significantly reduce second-order harmonic distortion, bringing out more detail and improving the sense of timing and pacing
- Has a power supply consisting of 5400VA of transformers and 188,000µF of filter capacitance for substantial power delivery
- Offers protection against excess direct current, short circuits, and voltage sags—brown outs
Product Considerations
- It may be too much power for some users
- High idle heat dissipation at 890 btu/hr per channel
Takeaway: The Krell KMA-i800 is a powerful amplifier with technologies that aim to provide a clean and controlled sound. Its high power output helps to improve sound quality even at average listening levels.

Our take on the brand
Our Summary
Product Strengths
- Designed to drive even very low-impedance loudspeakers without compromising distortion levels
- Delivers unmatched sound clarity and power with a maximum power output of 1050 watts RMS at 8 ohms and a total harmonic distortion (THD) of only 0.005% across 20 Hz to 20 kHz
- Features a damping factor of 600 at 1 kHz and output floor noise of less than 3 μV, delivering an impeccably clean and detailed sound free from unwanted background noise
- Ensures maximum thermal security and short-circuit protection with fully analog circuitry from input to output and an automatic shutdown feature
- Equipped with analog and digital inputs, including RCA and XLR connectors
Product Considerations
- A preamp is required to supply input switching and any processing needed before sending signals to the Telos 4800 to power the speakers
- As a mono power amp, two units are required for a stereo setup, increasing the overall cost significantly
Takeaway: The Telos 4800 is designed to meet the needs of any audio system and delivers unmatched sound clarity and power. With impeccable specs, it offers a high-end performance for audiophiles.
