The THÖRESS DFAmp is a dual-function vacuum tube amplifier that serves as both a line control amplifier and a headphone driving amplifier. It uses a minimalist single-ended, zero-feedback circuit with very low output impedance, allowing it to drive long interconnect runs and headphones down to 50 ohms or lower. The unit also includes selectable tone control presets (timbre registers) and a motor-driven remote volume control. Pricing found in sources varies slightly by dealer, with an MSRP/SRP of about $14,140 to $14,999.
