Ultra high end performance in a small package. Purely passive Autotransformer design wired throughout with Fractal-Wire™ to perfectly match any source component with any power amplifier. No mains noise, no electronic hash and no requirement for esoteric mains conditioners or power cord. The Allegri+ Passive Autotransformer preamp is exceptionally transparent, has absolutely no noise and has enormously wide bandwidth. It has vanishingly low distortion, very powerful and deep bass and amazing drive throughout the audio band. Treble is crystal clear with not a hint of hardness or brashness. It just sounds right!

The nature of the transformer design eliminates the problems usually associated with resistive passive controls. At the zero dB setting the input signal is directly connected to the output. This means that the output impedance of The Allegri+ is the same as the output impedance of the source component. Further, the input impedance of The Allegri+ is equal to the input impedance of the power amplifier at this setting.

Preamps of today do not require gain as all quality source components have an output of about 2 volts with a low output impedance. Any competent power amplifier will achieve full output with typically 1 volt and have a high input impedance. Unlike conventional passive controllers the Townshend Allegri+ matches the impedance requirements of source and amplifier so that full dynamics are retained.
