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:
- They deliver a sound that is musical and emotional, aiming for an involving experience rather than sterile hi-fidelity.
- Components are often modular in design, constructed with matched transistors and high-quality components and local shunt-regulated power supplies, allowing for interchangeability and future upgrades.

RS-101
- Positioning: Entry-level stereo power amplifier in the Reference Series.
- Description: Offers 300W per channel at 8Ω. Features an intelligent Class A bias for enhanced musical detail, distinguishing it from higher-end models like the SS-025, which offer more power and refinement. This model is ideal for those seeking high performance at a more accessible price point, without the advanced features of the Signature or Masterpiece series.
SS-025
- Positioning: Mid-range stereo power amplifier in the Signature Series.
- Description: Delivers 300W per channel at 8Ω, similar to the RS-101, but with enhanced clarity and musicality due to its design based on the SIA-025 and SM-011. It offers a more refined soundstage compared to the RS-101.
MP-S201
- Positioning: High-end stereo power amplifier in the Masterpiece Series.
- Description: Stands out with its massive 500W per channel at 8Ω, doubling the power of the SS-025, and includes a mono mode for bi-amping. Its superior build quality and power make it ideal for large 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
- Crisp, tight rhythms are allied to a sonorous, close-focused view of vocals
- Capable of bags of detail and definition, while bathed in a lovely warmth
- Massive bass weight is available, with fabulous rosiny bite to the low strings, silky violins, and the feeling of space and air around the performers
- Big, substantial sound makes the most of remasters, bringing out all the character of vocals
- Focus and warmth contributes to a solid, three-dimensional soundstage, and remains clean and tight when cranked
Product Considerations
- The precious bottles should never be left unattended or used without the purpose-designed glass hood installed
- The amps' thermal characteristics may be a problem in a globally-warmed English summer
- Each amp draws 430W from the wall
Comparisons (according to reviewers)
- Vs Dan D'Agostino Relentless Monoblocks—the ERIC Encores are more expensive per watt
Takeaway: The Engström ERIC Encore Mono Power Amplifiers offer a captivating and enthralling presentation that challenges old clichés about valve amps. One should hear them if given the chance, for they sound glorious.

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.
