Pros
Exceptional transparency, fine detail retrieval and a dead-silent background, even with highly sensitive speakers.
Huge dynamic reserve and effortless control with low-sensitivity, hard-to-drive loudspeakers.
Expansive, three-dimensional soundstage with convincing depth and image layering.
Outstanding build execution, including highly praised transformers, internal components and separate power supply.
Cons
Large, heavy two-box design requires careful placement and likely two people to move.
Needs a lengthy burn-in period; bass punch and transparency were initially less convincing.
Manual tube biasing and finite tube life add ownership effort.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 95/100
The review portrays the EOS as an unusually transparent, fast and authoritative tube amplifier rather than a conventionally soft or overly romantic one. It combines very high resolution and a silent background with expansive, holographic spatial presentation, while retaining an effortless grip on demanding loudspeakers.
Transparency Resolution
96/100
Soundnews repeatedly praises the EOS's cleanness, transparency and unconstrained detail, describing it as nearly invisible between source and speakers. The reviewer was also struck by its dead-silent background even with Raidho's highly sensitive planar-magnetic tweeters.
Tonal Balance Musicality
92/100
The EOS is described as natural, bold and effortless, with tube character present but not dominating its fundamentally clean and direct presentation. Treble is said to be neither bright nor dull, with strong extension; the reviewer notes an initial lack of bass punch before burn-in, which slightly tempers the otherwise enthusiastic account.
Dynamics
95/100
The reviewer calls the power reserve huge and says the EOS remained effortless throughout listening, including with 84dB loudspeakers. Rapid instrumental attack, substantial dynamic swings and its rewarding performance with hard-to-drive speakers support its commanding delivery.
Soundstage Imaging
96/100
Spatial performance is a major strength in the review, with music depth at times extending beyond stage width. The presentation is described as enveloping, three-dimensional and holographic, producing a convincing sense of being surrounded by performers.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
95/100
The EOS uses a separate power-supply enclosure, KT120 output valves, RCA and XLR inputs, and dedicated 4- and 8-ohm outputs. More importantly, the reviewer specifically praises its transformers and internal components as difficult to better at the price, indicating exceptionally serious engineering execution.
Value for Money
95/100
Although no retail price is provided, Soundnews explicitly states that better transformers and internal components are unlikely at this price and that substantially more spending would bring only marginal sonic gains. That is unusually strong praise for its competitiveness against pricier alternatives.

Manufacturer's Description — Trafomatic Audio
The EOS power amplifier is the second one by power in the Trafomatic Audio productions. It is constructed as dual mono push-pull using well known KT120 output tubes.
Output power is 100W per channel, which is sufficient for most speakers, even those with lower than average sensitivity. This is a power amplifier, requiring preamplifier and opening endless possibilities for system configuration.
Based on previous work on negative feedback, -8dB reaction has been tuned to provide sound equivalent to a good Single Ended application. Cathode feedback was used as the most musical one. Bass is well controlled, dynamic response is excellent and this amplifier belongs to the very top of its class.
Well designed power supply made as separate unit utilizes 800VA toroidal transformer and C-L-C filter separated for each channel. Output transformers are based on a Double-C core configuration and Solen fast capacitors are used throughout. Adding well thought-out concept to the mix results in a recognizable high quality sound of our amplifiers.
The new modern styling of Trafomatic Audio amplifiers has been extended to this model as well,which makes a perfect sonic and visual fit with your room.
An excellent starting point for full immersion in good sound. See and hear for yourself.
