Thrax Audio, the Bulgarian high-end audio manufacturer renowned for its no-compromise engineering, today announced the COTYS, a revolutionary moving-coil phono preamplifier that challenges decades of industry conventions. Designed by founder Rumen Artarski after 30 years of user feedback and personal refinement, the Cotys is built for modern MC cartridges—delivering the lowest noise, utmost flexibility, and uncompromising sonic purity.
A PHONO PREAMPLIFIER THAT IGNORES TRADITION, ELEVATES PERFORMANCE
The Cotys discards legacy design limitations with a fully balanced, LCR-based RIAA equalizer, engineered to unlock the full potential of today’s high-performance moving-coil cartridges. Its innovative differential input stage and nano-crystalline inductors set a new benchmark for low-noise, high-dynamic-range playback—whether for rare vinyl pressings or cutting-edge audiophile releases.
KEY FEATURES
- Dual Moving-Coil Inputs – Precision-matched for low-output and high-impedance cartridges.
- Balanced Differential Topology – Eliminates ground loops and common-mode noise
- Ultra-Low Noise Architecture – A differential input stage with -sub 70nV noise for blacker backgrounds.
- True LCR Equalization – Nano-crystalline inductors and copper-foil capacitors for phase-perfect RIAA correction.
- Fully Configurable Loading/Gain – Touchscreen interface for impedance (100Ω–1kΩ) and gain (50–70dB) adjustments.
- Future-Proof Design – Field-upgradable firmware and optional external battery power supply.
- Uncompromising Build – Machined from a single aluminum block, with universal AC input for global use.
WHY THE COTYS DEFIES EXPECTATIONS
“Most phono stages are designed around compromises—passive EQ, noisy gain stages, or loading that doesn’t suit modern cartridges. The Cotys eliminates all of it. This is a phono preamplifier where every decision was driven by performance, not convention.” – Rumen Artarski, Founder, Thrax Audio
With all the features and technology Cotys breaks another barrier by being the first Thrax electronic product in the sub $10,000 category.
