What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
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.

300B Integrated Stereo Power Amplifier
- Positioning: The entry-level integrated amplifier offering basic stereo power in a compact design.
- Description: Comes with 5W per channel, headphone and speaker outputs, and multiple inputs, making it ideal for small rooms and those on a budget. Compared with higher models that feature interstage transformer coupling or dual chassis designs, it provides straightforward functionality without additional circuitry complexity.
300B Single Ended Stereo Power Amplifier
- Positioning: A mid-tier stereo amplifier designed to deliver slightly higher power and improved sonic clarity.
- Description: Offers 8W per channel with interstage transformer coupling and a 6SN7 driver tube, making it better suited for users needing more performance than the integrated version. Compared to the entry-level model's simplicity, its design brings enhanced power handling and sound reproduction without resorting to separate mono chassis modules.
300B Single Ended Mono Power Amplifiers (2 chassis)
- Positioning: A pair of mono amplifiers in a dual chassis setup aimed at providing focused, balanced sound.
- Description: Delivers 8W per channel using interstage transformer coupling and the 801A directly heated driver tube. Relative to the stereo units, their dual chassis design offers improved channel separation while keeping costs lower than more complex assemblies.
300B Single Ended Mono Power Amplifiers (4 chassis)
- Positioning: A refined pair of mono amplifiers featuring a four chassis design with external power supplies for enhanced stability.
- Description: Provides 8W per channel with the same high-quality tube and transformer coupling but adds improved thermal management for greater reliability in larger or critical listening settings. When compared with the 2 chassis model, the extra chassis and external supplies deliver better performance consistency.
300B Single Ended Mono Power Amplifiers - Silver
- Positioning: The flagship mono amplifier pair engineered with silver wound transformers for premium performance.
- Description: Uses silver wound transformer technology to reduce distortion and achieve tighter sound control. Compared to all other models in the lineup, its enhanced build quality and precise transformer design set it apart as the top choice.

Our take on the brand
VinylSavor stands out for its unique use of transformer coupling and transformer volume control in preamps, along with vacuum tube rectified high voltage supplies and low impedance circuits. The brand's equipment, personally built and tested by Thomas Mayer, is engineered with custom-made transformers and multiple chokes for excellent power supply performance, eliminating the need for expensive power conditioners or exotic cables.

Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
Fully transformer coupled designs. The use of directly heated triodes not only as output tube but also as drive rand preamp tube. 600 Ohm LCR RIAA EQ in phono stages. Custom triodes for the Intrepid series (Thomas Mayer ONE, TWO and THREE). Possibility to customise each product to specific needs.
What's your approach to customer support?
I sell directly to end customers. I used to have very few resellers but due to the steep increase of production and material costs I exclusive do direct sales now to avoid price increases of the products which would otherwise be necessary. My goal is that every customer is happy and I am always available for any questions even years after the sale. When necessary I do repairs or assist in set up at the customer site.
What are your favorite tracks for showcasing the strength of your products?
I don’t have any favourite tracks, but use whatever I am in the mood for. Equipment should not be designed to work with specific music. People should use music they like for testing
What other products pair best with yours?
Admire Audio speakers.

Dan D'Agostino
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.

Eric Encore
174965
/
Released
2021
Named after a great Swedish choir conductor, ERIC is our no-compromise statement power amplifier. Fully balanced and transformer-coupled, it was created to drive even the toughest loads. ERIC uses separate power supplies for input and output stages and DC filaments.
Engström is a Swedish hifi brand that handcrafts amplifiers with a minimalist Nordic design, featuring fully balanced, transformer-coupled circuits and no negative feedback to preserve natural sound dynamics. Their amplifiers, which use KR Audio's T-100 power tubes, are known for creating an expansive, three-dimensional soundstage with what audiophiles call a "Scandinavian Sound"—characterized by open, detailed, and natural sonic qualities.
Expand Details
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.
