What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- High amounts of power, supreme bass weight, and woofer control
- Velvet-smooth sound throughout the audioband, particularly in the midrange, with high resolution
- Images with tube-like dimensionality, creating soundstages of convincing depth
- Sound reproduces without colorations
- Functions flawlessly, with no operational glitches, and is bulletproof in terms of safety and reliability with a comprehensive monitoring system
Product Considerations
- The MTRX2s are big and heavy, making them difficult to move and install
- The MTRX2's big, blocky look was not well-received
- High power output might be overkill for rooms of typical size
- The balanced (XLR) and single-ended (RCA) inputs seem of good quality, if nothing extraordinary

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

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:
Select products
Select product comparisons
DV2I:
- Positioning: The entry-level digital control unit designed for affordability and a compact design.
- Description: Offers a simple digital volume control with smart integration that suits small room setups and basic functionality needs. In comparison, while DA2I and EMM PRE add more power and refined signal handling, the matrix devices (MTRS and MTRX2-V2) bring extra switching features for more complex connectivity.
DA2I:
- Positioning: A versatile amplifier module positioned for users needing a balance of performance and efficiency.
- Description: Provides a clear amplification path with a distinct design that improves transient response and sound clarity. Relative to the basic DV2I, it offers enhanced power output while still remaining more focused than the higher-end preamplifier EMM PRE and the multifunctional routing modules.
EMM-PRE:
- Positioning: A high-performance preamplifier tailored to deliver precise control over audio signals.
- Description: Features a refined preamp circuit that minimizes distortion and secures a clean signal to drive complex audio setups. When compared to the amplification options like DV2I and DA2I, it delivers better fidelity and controllability, though it lacks the expanded routing capability of MTRS and MTRX2-V2.
MTRS:
- Positioning: A dedicated routing unit designed for audio matrix switching across multiple sources in versatile systems.
- Description: Uses a focused switching architecture that reduces signal interference and loss, making it suitable for setups requiring clear source selection. In contrast to the core amplification and preamplification units (DV2I, DA2I, and EMM PRE), it emphasizes connectivity and switching functions, though it sits below the most advanced routing system in the lineup.
MTRX2-V2:
- Positioning: A premium routing and switching system built for advanced performance and extensive connectivity in complex installations.
- Description: Integrates a matrix design that ensures precise signal routing with low latency and minimal interference. Compared to all other products in the lineup, it meets high functionality demands.

Relentless 800
195500
/
Released
2023
After setting the measure for amplifier excellence, the new Relentless 800 Mono Amplifier extends the Relentless sound quality to a smaller platform. Every major section of the Relentless circuitry - power supply, input, driver, and output stages - have all been enhanced and these all feature in the new Relentless 800. The Relentless 800 incorporates the same circuit platform as its bigger brother with a lower power output. Mind you, the Relentless 800 is virtually unlimited when it comes to power delivery and is only outdone by the Relentless 1600 itself. Nuanced and musical at low volume levels, the Relentless 800 delivers the striking dynamic contrasts – that brings music to life.
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
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.
