What's unique about the brand

Thrax Audio is distinguished by its use of transformers for volume control instead of traditional potentiometers in their Dionysos preamplifier, and their Spartacus amplifier features a unique two-stage shunt regulated Directly Heated-Triodes push-pull design in pure class-A with no feedback.

What reviewers are saying

We read all the reviews. Here's what reviewers feel most strongly about:

  • Thrax designs its products with a "total system" approach, where each component (preamplifier, amplifier, speakers) is designed to work synergistically, optimizing the overall system performance.
  • The brand blends tube and solid-state technologies in unique ways, leveraging the strengths of each to achieve a sound that is both detailed and musical.
  • The design and aesthetic of Thrax products are meticulously crafted with high-quality materials like milled aluminum, offering a sophisticated and modern appearance.
  • Thrax amplifiers are designed to perform optimally without negative feedback, maintaining tonal purity and offering high resolution at all power levels and loads.

Our favorite reviewer quotes:

  • "The Thrax Audio Libra preamplifier is simply more than just a remarkable audiophile device that transcends both solid-state and tube designations. It punctures directly and deeply into the music, presenting it with unsurpassed authority." (https://www.monoandstereo.com/thrax-audio-libra-300b-preamplifier-review)
  • "The Teres possesses a very quiet and super transparent footprint and produced a mesmerizing three-dimensionality stage. So much in fact, the Teres sounded as though I moved my speakers further away." (https://www.stereotimes.com/post/thrax-audio-teres-hybrid-mono-amplifier)
  • "Was it because of elimination of cabinets resonances, or usage of amazingly linear C3g tube, (whose cousin, C3m, I knew from some other top products), or most likely due to many elements working together, these speakers create a dense sphere made of air, sounds, details that surrounds listener. If only recording we play allows that." (https://positive-feedback.com/Issue78/thrax_teres.htm)

St. Teres

  • Positioning: Positioned as a high-performance stereo amplifier in the Thrax lineup.

Heros
