Trafomatic Audio EOS
The EOS integrated amplifier is the most powerful integrated amplifier in the Trafomatic Audio productions. It is constructed as 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 integrated amplifer and doesn’t requiring preamplifer. Based on previous work on negative feedback, -6dB 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 amplifer 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.

Trafomatic Audio EOS — Integrated tube powerhouse
The EOS is a muscular, finely engineered integrated tube amplifier that pairs tube warmth with startling transparency. As reviewed by Catalin Cristescu for Soundnews, it delivers 2x100W (first 10W in pure Class A) from a push-pull KT120 topology with a substantial external PSU. Sonically it is bold, fast and exceptionally detailed, offering a wide, three-dimensional soundstage and an impressively dark noise floor. Performance highlights include huge power reserve, tight dynamics and refined imaging, while build quality is defined by hand-wiring and premium Double-C transformers. Ideal for listeners who want tube character without compromising headroom — it pairs especially well with modern or hard-to-drive speakers and supports a robust headphone output for critical listening.
Pros
- Massive power reserve and headroom — drives low-sensitivity speakers effortlessly.
- Exceptional transparency and micro-detail retrieval with a very low background noise.
- Robust, high-end construction with separate heavy power supply and premium transformers.
&
Cons
- Large and heavy two-box design makes placement and handling demanding.
- Requires long burn-in and manual biasing; tubes are finicky and need periodic attention.
- Runs hot in operation and tube availability/replacement can be an added long-term cost.

Class AB 2x100W that offers large power reserve and headroom: reviewer calls the EOS 'effortless the whole bloody time' and able to drive low-sensitivity (84dB) speakers. Mentions of 500W bursts and controlled delivery support a high dynamics score.
Soundstage Imaging
92/100
Reviewer describes a vivid 3D, holographic presentation — 'surrounded by the performers', 'depth of the music could extend sometimes beyond the width' — indicating strong width, depth and image focus.

Build Quality
92/100
Reviewer highlights top-tier transformers and internal components for the price point and mentions substantial external power supply (25kg + 11kg split), implying robust construction and a serious power supply implementation.
Features Connectivity
85/100
Offers 3xRCA and 1xXLR inputs, remote volume control and a capable headphone output (25-150 ohms, 3W @50Ω). Lacks onboard DAC, phono stage, digital/streaming inputs or subwoofer output, so functionality is strong for pure analog setups but not fully featured.
Value for Money
90/100
Reviewer explicitly states you 'probably won't find better transformers and internal components at this price point' and that you'd need to spend significantly more for marginal gains, characterizing the EOS as a well-justified premium buy even though a numeric price wasn't provided.
