What reviewers think
Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.
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.
Prestige Series
- Positioning: The entry-level lineup offering high-quality audio performance with accessible designs.
- Description: Delivers impressive sound quality through carefully engineered components. While it provides a solid foundation, it lacks the advanced technologies found in the higher-tier Reference and Signature Series, resulting in comparatively less refined audio reproduction.
Reference Series
- Positioning: Mid-tier products that introduce enhanced features and performance over the Prestige Series.
- Description: Incorporates improved circuit designs and higher-grade materials, offering a more detailed and dynamic listening experience. However, it doesn't include the proprietary Inverted Triode technology present in the Signature Series, which limits its ability to deliver the same level of sonic purity and realism.
Signature Series
- Positioning: High-end products featuring Aries Cerat's proprietary technologies for superior audio fidelity.
- Description: Stands out with the implementation of the unique Inverted Triode technology, providing exceptional linearity and low distortion. This results in a more natural and immersive sound compared to the Reference Series.
Limited Edition Series
- Positioning: The flagship lineup representing the highest level of craftsmanship and audio performance.
- Description: Features top-of-the-line components and exclusive designs, such as the dual-chassis configuration for improved isolation and power supply integrity. This meticulous engineering surpasses the capabilities of the Signature Series, delivering extraordinary soundstage and detail retrieval.

Our take on the brand
Aries Cerat is a hifi brand known for its use of oversized components and TriodeFet technology, which combines tube and solid-state designs to create a distinctive sound signature. Their products, including the Kassandra DAC and Symphonia horn speakers, are built with massive power handling capabilities and carefully selected drivers to deliver a muscular, dynamic sound that rivals top analogue systems.

Dan D'Agostino
The new Relentless Preamplifier is the ultimate in preamplifier design. The preamplifier plays a critical role in musical playback; the point in the reproduction stage when the music signal is particularly susceptible to compromise through noise and distortion. The use of three separate chassis in the design of the Relentless Preamplifier—a dedicated audio chassis for each channel separated by a power supply/control section—addresses these challenges and brings other benefits as well.
Dan D'Agostino is an ultra-premium hifi brand distinguished by its unique copper heat sinks with holes and distinctive circular green-lit VU meters that give their amplifiers a steampunk aesthetic. Their amplifiers feature proprietary "Super Rail" technology that maintains high voltage for front-end transistors, while their three-chassis Relentless Preamplifier uses 30-pin interlocking connectors to eliminate wiring anomalies.

Our Summary
No items found.
Product Strengths
- Over-engineered, hugely heavy, and XLR-balanced-only design aimed at clients who accept balanced-only systems
- 'Dual Zone' functionality provides two playback zones with independent sources for each
- The two mono preamp chassis form a sandwich with the power supply/control section in between, communicating through interlocking gold-plated 30-pin aerospace connectors, eschewing cabling between the three sections
- The heavily shielded power supply is housed in its own chassis, which is intended to sit between the boxes housing the two audio channels, incorporating internal line conditioning circuitry
- Volume control knobs are very smooth, and the volume control has no sweet spot
Product Considerations
- XLR-balanced-only design might require adapters for RCA-only devices
- The remote control was initially a 'huge, weighty affair', though a new version was almost ready at the time of review
Takeaway: The D'Agostino Relentless Preamplifier is an extremely well-engineered, high-end product intended for those wanting the best possible audio quality and are unconcerned about cost. It offers unique features such as dual-zone functionality and a sophisticated multi-chassis design.

Our Summary
Product Strengths
- The 3010 offers a wealth of controls, including six pairs of outputs which can be separately attenuated, and a 'blend' function to change stereo to mono
- Notes start and stop precisely, but in a refined manner, and grace notes appear fleetingly before disappearing
- Startlingly pure reproduction, especially noticeable on smaller-scale recordings
- Captures the ringing peal of the organ in the nether regions with great power, and distinguishes tonal fidelity
- Music 'rips without any compression', and sorts out complex musical passages
Product Considerations
- If you prefer the sound of tubes, the Boulder 3010 will not give you a sumptuous tonal balance or holographic soundstage associated with tubes, because it seeks fidelity to the source
Takeaway: The 3010 offers precision and clarity in music reproduction, making it a highly addictive listening experience. The 3010's control and accuracy allow the music to breathe freely.

Our take on the brand
Boulder is among the elite tier of hifi amplifier brands. Based in Colorado, they are recognized for their exceptionally low-noise and high-power Class A and Class AB amplifiers. They are frequently cited as "dream systems" by audiophiles and reviewers.
