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.
At -6dB (output voltage half the input voltage), the input impedance of The Allegri+ is four times the input impedance of the power amplifier and the output impedance of the Allegri+ is one quarter of the source impedance.
At -20dB (10 to 1), the input impedance of the Allegri+ is one hundred times the power amplifier impedance and the output impedance of the Allegri+ is one hundredth of the impedance of the source component. It is thus clear that the interconnect cable capacitance will have no effect on the performance of the Allegri+.
There are no coupling capacitors or active devices in the signal path in The Allegri+ and the absence of a noise-injecting power supply guarantees ultimate sound quality.
The Allegri+ has a six-position input selector, a mute switch and a 24-position volume control with intervals chosen to cover a wide range of volume levels in different systems. Its state-of-the-art autotransformers are wound with Townshend Audio Fractal-Wire™ and laminated with ultra-thin mu-metal laminations for the highest possible resolution. There are six pairs of gold plated stereo phono inputs and two pairs of outputs and a 3.5mm input jack on the front panel. The case is made of anodised aluminium.
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.
Fractal-Wire ™ results in the most accurate, uncoloured and open-sounding preamplifier possible – with astonishing transparency and resolution of fine detail. It is DC coupled with no capacitors in the signal path.
It is essential to use F1 Fractal-Wire™ interconnects for both input and output of the Allegri+, so as not to compromise the profound advantage of the Fractal-Wire wound transformers.
For the very best sound quality, we recommend optimising you system by using Townshend F1 Fractal™ Interconnects and F1 Fractal™ Speaker Cables.
Female XLR to Phono and Phono to male XLR adaptor cables are available separately, enabling full balanced operation.
