Thrax Heros MK II

Thrax Audio is a Bulgarian manufacturer founded in 2009 by Rumen Artarski, a lifelong audio enthusiast whose passion for sound engineering began in childhood. Artarski's journey through Denmark, where he studied electronics and acoustics at the Danish Technical University, and later London, where he worked in record production, shaped his philosophy of marrying sonic excellence with user-friendly design. The company's name derives from the ancient Thracian region, reflecting Artarski's desire to create timeless objects of beauty. His vision crystallized when he designed a remote-controlled tube preamplifier that could rival the sonic performance of prestigious brands like Wavac and Kondo Audio Note.

Thrax Audio specializes in tube-based electronics and speakers, with a product portfolio encompassing preamplifiers, integrated amplifiers, and loudspeaker systems. The company is distinguished by its commitment to in-house manufacturing of virtually every component except tubes themselves, employing multiple 300B tubes in flagship models like the Spartacus amplifier and Libra preamplifier. Recent product expansion includes a DAC, broadening the company's reach within the high-resolution audio ecosystem. Artarski leads a design team of five specialized engineers, including experts in tube circuit design with decades of experience.

Thrax Audio occupies the ultra-premium segment of the high-end audio market, positioning itself among the world's most exclusive and uncompromising manufacturers. Pricing reflects this positioning, with flagship components commanding five-figure investments. The brand has cultivated a reputation for sonic sophistication and meticulous engineering, earning recognition at major international audio shows and among discerning audiophiles who prioritize tube-based warmth and detail over mass-market convenience. Thrax represents a niche boutique approach where artisanal craftsmanship and extensive listening validation drive product development.
