The EOS is a stereo power amplifier from Trafomatic Audio, sharing its model name and electrical specifications with the brand's EOS integrated amplifier, offered here as a dedicated power amplifier chassis. The EOS brings Trafomatic's considered engineering to dedicated stereo power amplification.
Key specs that matter
Input sensitivity is 1,000mV, with input impedance at a substantial 100,000 ohms on both connections. Output power is 2 x 100W into 8 ohms, matching the EOS integrated. Frequency response spans 10Hz to 100,000Hz within plus-or-minus 3dB, also matching. Signal-to-noise ratio is 82dB, with total harmonic distortion plus noise at 0.03% at 100% global feedback. At 150 x 300 x 200mm and 25kg, the EOS power amplifier maintains the compact chassis dimensions typical of Trafomatic's power supply modules.
Sound and use context
Expect the rich, harmonically resonant character tube-based amplification is broadly celebrated for, matching the electrical performance of Trafomatic's EOS integrated amplifier in a dedicated power-amplifier-only format.
Pairing
A separate preamplifier is required to complete the signal chain, and Trafomatic's own Evolution Line One offers a natural, brand-coherent pairing.
Alternatives
Trafomatic's own Evolution Elegance offers a related stereo power amplifier alternative within the same broader catalogue.
