About the TL-7.5 III
The VTL TL-7.5 Series III Reference Preamplifier is a flagship two-chassis design separating audio circuitry from power supply and controls to minimize noise. It employs a hybrid topology with 12AU7 tubes in the gain stage for voltage linearity and FET-based output buffers for current drive, incorporating zero global negative feedback for enhanced dynamics and tonal resolution. Key upgrades include a current-sourced shunt-regulated power supply, audiophile-grade Mundorf capacitors, microphonically damped tubes, and a 95-step relay attenuator using ruthenium relays. It offers intuitive user interface with RS-232 control, programmable inputs, and compatibility with modern systems, delivering exceptional coherence, transparency, and tube-like sound.
