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
- Gorgeous, velvet-smooth sound throughout the audioband, and particularly in the midrange, it was rich and sultry with most recordings, yet with all the resolution one could hope for
- Revealed everything
- Could image with tube-like dimensionality, laying out soundstages of depths so convincing they were sometimes uncanny
- The quality of metalwork is among the best seen or laid hands on, the finely textured metal surfaces felt like suede
Product Considerations
- The MTRX2 is big and heavy, each measuring 21.4"W x 11.7"H x 23"D and weighing 180 pounds
- The MTRX2's big, blocky look was not appealing to the reviewer
- Potential buyers should be careful when installing them due to their weight
Takeaway: The EMM Labs MTRX2 mono amplifiers provide a super desirable listening experience with high power and extremely high resolution and build quality. If you want to hear sound without colorations and with velvet-smooth delivery, these could be the right amps.
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.

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.
