Thermidt
Hi Fi Tube Amplifier
Experience Rich, Detailed, and Vibrant Sound
Thermidt is voiced for audio enthusiasts and professionals who value musicality as much as precision. Its Negative Cathode Feedback (NCF) design enhances clarity, tightens low-frequency response, and improves overall stability, allowing recordings to sound alive yet controlled.
Precision Tube Design for High-Fidelity Performance
Operating in Class AB push-pull with fixed bias, Thermidt delivers 2 × 21 W with distortion kept below 0.15% at 20 W. The power stage uses four 7189 / 6N14P-EV tubes, driven by dual 6BL8 triode-pentodes, while the preamp stage supports either 6N2P-EV or 12AX7 tubes via a selectable jumper. Three listening modes—Flat, Bass, and Loudness—allow fine tailoring of tonal balance.
Robust Elegance with Thoughtful Details
An 8 mm CNC-machined top plate anchors the design, combining durability with understated elegance. Carefully engineered ventilation creates a chimney-effect cooling path, extending tube lifespan. Gold-plated speaker terminals, Cinch inputs, and intuitive controls ensure a refined user experience.
Seamless Connectivity and Enduring Reliability
With 775 mV RMS input sensitivity, Thermidt integrates effortlessly with CD players, TVs, AUX sources, and a built-in DLHiFi 5.1 Bluetooth module supporting 24-bit / 192 kHz streaming over long distances. Custom Z11 grain-oriented steel output transformers, designed exclusively for this project under UTM Industry supervision, ensure lasting performance and exceptional sonic integrity.
