PUSH-PULL TUBE AMPLIFIERS
TRAFOMATIC
Where the Heart and the Soul meet Innovation
At Trafomatic Audio we don’t take any of the usual high-end audio norms as standard.
We’re setting new standards by moving the bar to extremes in each of our products. We strive for a level of excellence that goes beyond what the industry has tried to impose on listeners for the past few decades. Where most stop, our journey just begins.

The EOS Integrated amplifier is one of the most powerful integrated amplifiers in the Trafomatic Audio line. It is constructed as push-pull using the 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 amplifier and doesn’t require a preamplifier.
Based on previous work on negative feedback, -6dB has been applied to provide a sound equivalent to a good Single Ended circuit. Cathode feedback was selected for enhanced musicality. Bass is well controlled, dynamic response is excellent. As such, and this amplifier is top of its class.
A well designed out-board power supply unit utilizes a 800VA toroidal transformer and separate C-L-C filter circuit per channel. Output transformers are based on a Double-C core configuration, and Solen fast capacitors are used throughout.

The EOS + amplifier is a similar in design to the EOS. It is a more powerful push-pull version using the most powerful of the current production KT tube - the KT150.
Output power is a hefty 150W per channel, which drive speakers with demanding loads. The EOS+ is available in two versions : a stereo power amplifier, and an integrated amplifier that doesn’t require a preamplifier. And, given Trafomatic's Head-Fi origins, it is kind of second nature for them to include "Uber-Hi-End Headphone-Service" in most of their components :=)) ... and the said "headphone service" involving a competent Headphone Output delivering a very potent 3W into 50 ohms !
But, back to the power stage : Based on previous work on negative feedback, -6dB has been applied to provide a sound equivalent to a good Single Ended circuit. Cathode feedback was selected for enhanced musicality. A well designed out-board power supply unit utilizes a massive 800VA toroidal transformer and separate C-L-C filter circuits per channel.
The Output transformers are based on a Double-C core configuration, and Solen fast capacitors are used throughout. As a result, Bass is well controlled and dynamic response is excellent.

The Elegance Evolution stereo push -pull amplifier is a successor of highly regarded and awarded Experience Elegance amplifier. This design id offered in both Integrated and Stereo Power Amplifier variants.
State of the art, no—compromise power supply and oversized output transformers (wound on Double-C cores) characterize the Elegance Evolution amplifier as another definitive audiophile product.
Description
The Elegance Evolution Integrated amplifier combines the output stage of our most powerful Evolution series amplifier with input switching, and a passive buffered attenuator (ALPS) driven by remote control.
The class AB power stage in ultra-linear mode produces 50 watts per channel from a quartet of push-pull connected 6550 (KT88). Manual setting of bias of each 6550 is new feature, and allows adjustment of the bias ... even on un-matched output tubes !
A small amount of cathode feedback lowers the output impedance and ensures excellent bass control and dynamics. Ab "all new" power supply greatly benefits from an oversized, proprietary Trafomatic Audio 300VA toroidal transformer, C-L-C filtering and Rubycon electrolytic smoothing capacitors.
Excellent sound is achieved via the high-quality double C-core output transformers, and the exclusive Solen (fast caps) in the signal path.
Elegance Evolution amplifier was designed from the ground up to satisfy both demanding audiophiles and music lovers. It can drive speakers from 88dB with authority, refinement and emotional impact.
Its potent and emotionally involving performance, combined with its high quality enclosure make it a very convincing Value Proposition.
