Description

The Thermidt High-End Tube Amplifier is a premium audio solution designed for enthusiasts and professionals who demand warmth, clarity, and dynamic precision. Built around a Negative Cathode Feedback (NCF) architecture, it delivers exceptionally clean sound with tight bass and stable performance which is ideal for both home hi-fi setups and studio monitoring. Its synergy with classic monitors like the Yamaha NS10 makes it an excellent choice for those who want to rediscover recordings or work on critical mixes with enhanced musical detail.

At its core, Thermidt offers 2 × 21W of Class AB push-pull output into 4 or 8-ohm loads, with a distortion factor under 0.15%. The tube configuration includes 7189/6P14P-EV power tubes, 6F1P drivers, and a 6N2P-EV or 12AX7 preamp tube, with selectable EQ modes (Flat, Bass, Loudness) for tonal flexibility. Connectivity is modern and robust, featuring three RCA inputs, a dedicated headphone output, and a built-in Bluetooth 5.1 module (QCC5125) supporting high-resolution codecs like LDAC and aptX HD, enabling 24-bit/192kHz wireless streaming with up to 100 meters of range.

Built to last, the amplifier features a CNC-machined aluminum top plate, engineered cooling vents, and custom output transformers made with Z11 grain-oriented steel for outstanding sonic fidelity. With refined aesthetics, thoughtful controls, and a shipping weight of 27 kg, the Thermidt is more than an amplifier so it’s a long-term commitment to high-performance analog sound, offering unmatched musical richness and a timeless listening experience.
