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:
- Engström's design philosophy centers on minimizing "disturbance" to the audio signal, prioritizing the preservation of the music's inherent structure and pattern over sheer power or technical specifications.
- They draw inspiration from Scandinavian design traditions, creating visually minimalist and elegant products with carefully considered aesthetics.
- The brand places a strong emphasis on achieving a "Scandinavian sound," characterized by naturalness, clarity, and musical articulation.
- Engström amps are known for their ability to work with a wider range of loudspeakers than typical low-powered tube amplifiers, offering versatility in system matching.
Select products
MONICA
- Positioning: An entry-level line-stage offering flexible preamplification and phono capabilities.
- Description: Features a unique two-totem-pole design in a balanced configuration that separates pure signal processing from noise. Compared to Arne's integrated power and the dedicated power amps in Lars and Eric, it is ideal for users with smaller spaces and modest budgets who need essential functionality with versatile connectivity.
ARNE
- Positioning: A fully balanced integrated tube amplifier delivering 30W of power in a classic design.
- Description: Uses DC coupling between its driver and power tubes along with a symmetrical power supply to achieve fast transient response and low distortion. Compared to Monica's basic pre-stage approach and the specialized power amplifiers in Lars and Eric, it is well suited for moderate-sized rooms and mid-range budgets that favor a mix of vintage tube charm with modern engineering.
LARS
- Positioning: A dedicated, fully balanced Class A power amplifier featuring refined construction and a distinctive glass mantle.
- Description: Stands out with its glass outer mantle that creates a chimney effect for constant tube temperature and clear, pure sound. Compared to Arne's integrated design and Eric's high-power solution, Lars offers a traditional yet high-quality option for users with medium to larger rooms.
ERIC
- Positioning: A high-end, fully balanced transformer-coupled power amplifier delivering 70W per monoblock.
- Description: Features an advanced evolution to 845 power tubes paired with transformer coupling, which drives even the toughest loads with deep, expansive sound. Compared to Monica's basic preamplification, Arne's integrated approach, and Lars' classic performance, Eric is designed for larger spaces.

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.

Our take on the brand
Our Summary
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
Takeaway: The MTRX2 offers exceptional sound quality, high power, and reliability. If you desire a top-tier listening experience with no coloration and are seeking an end-game amplifier, the MTRX2 could be the perfect choice.
