THÖRESS Full Function Preamplifier MKII
Best vacuum tube preamp for discerning vinyl enthusiasts seeking sonic purity.
The THÖRESS Full Function Pre-amplifier (FFPre) MKII is a sophisticated vacuum tube device that masterfully combines a line control amplifier with a state-of-the-art phono equalizer. It features a purely active MC amplification stage with highly accurate RIAA de-emphasis and excellent signal-to-noise performance, eschewing step-up transformers. Built with meticulous hand construction and point-to-point wiring, it offers ultimate sonic refinement. The amplifier utilizes single-ended zero-feedback schematics and provides multiple phono and line inputs with selectable gain and impedance characteristics, alongside dual line outputs and a pass-through output.

Know before you buy
No, the FFPre MKII utilizes a purely active MC amplification stage. This design choice avoids the potential colorations associated with transformers, focusing instead on high signal-to-noise performance.
The unit features channel-separate manual volume controls on the front panel. This allows you to precisely balance the stereo image or compensate for slight channel imbalances in your source material.
Yes, the device is equipped with three dedicated phono inputs. This makes it an excellent choice for systems utilizing multiple tonearms or turntables.
The single-ended zero-feedback design is chosen for its sonic purity and natural harmonic structure. By avoiding global negative feedback, the amplifier maintains a more organic, transparent, and refined sound signature.
The pass-through output sends the signal from the currently selected source directly to another device, such as a headphone amplifier or a secondary power amp. It allows you to integrate the FFPre MKII into more complex audio systems without needing to swap cables.
The FFPre MKII provides selectable gain and impedance characteristics to accommodate a wide range of moving coil cartridges. You can configure these settings to ensure optimal matching with your specific phono cartridge.
