The Thoress Super Full-function Tube Preamplifier incorporates a state-of-the-art line control amplifier and a ground-breaking phono stage in one case. The preamplifier is entirely hard-wired and much care has been taken in arranging each aspect of the internal construction to ensure low noise performance, the highest reliability and total ease of service. The Thoress preamplifier offers the best possible sound from both line and phono sections, making it a reference device.

The sound quality of the Thoress Preamplifier is of the utmost refinement and will certainly measure up to the expectations of even the most critical and experienced music enthusiast. The phono section within the “Super” employs one PCC88 and two 12SN7GT tubes. Thanks to an outstanding circuit topology, amplification of the moving coil signal is purely active (no built-in step-up transformers) and an extraordinary signal-to-noise ratio has been achieved. In addition, the circuit has been designed to maintain extremely accurate RIAA equalization independently of tube parameter tolerances and tube ageing.

The Super offers a total of six inputs for line level and MC phono sources. The customer can custom order the desired number of inputs for each source according to their requirements. Furthermore, each phono input allows custom resistance loading.

Importantly, the output resistance of the main outputs is low enough to drive long interconnect cables and input impedances as low as 10,000 ohms (solid-state amplifiers or an active subwoofer).
