Integrated amplifiers — Trafomatic Audio EOS

The EOS is a distinctive tube integrated amplifier with built-in headphone amplifier from Trafomatic Audio, a well-established Serbian manufacturer known for accomplished, transformer-focused tube electronics engineering, built with a separate outboard power supply and considerable combined mass. The EOS brings Trafomatic's considered engineering to a substantial dual-chassis tube integrated format.

Key specs that matter

One balanced XLR input and three single-ended inputs are provided, alongside the built-in headphone amplifier. Input sensitivity is 600mV, with input impedance at a substantial 100,000 ohms on both connections. Output power is 2 x 100W into 8 ohms. Frequency response spans 10Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 82dB, with total harmonic distortion plus noise at 0.03%. The main chassis measures 450 x 350 x 230mm at 25kg, with a separate power supply measuring 150 x 300 x 200mm at 11kg.

Sound and use context

Expect the rich, harmonically resonant character tube-based amplification is broadly celebrated for, with the separate outboard power supply reflecting serious transformer engineering, consistent with Trafomatic's broader considered Serbian philosophy.

Pairing

The built-in headphone amplifier offers genuine convenience for headphone listening directly from the same chassis.

Alternatives

Trafomatic's own Elegance Evolution offers a single-chassis alternative within the same broader catalogue.
