Townshend Audio Allegri preamplifier

  • 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

Unrivalled sound quality with crystal clear treble, open mid-band and subterranean bass

The preamp/control unit is the heart of any hi-fi system. The Allegri Passive Autotransformer preamp is a very small control unit with a very big heart. It is rated by some very critical and highly experienced high-end hi fi reviewers as the best sounding preamp at any price. It is exceptionally transparent, has absolutely no noise and enormously wide bandwidth. The Allegri 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! 

Ultra high end performance in a small package

The Allegri Passive Autotransformer 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 metal laminations for the highest possible resolution. There are six pairs of gold plated stereo phono inputs and two pairs of outputs. The case is made of anodized 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. 
  • Autotransformer Passive Stereo Preamplifier A high fidelity line level controller that selects 6 RCA phono inputs, adjusts gain and provides 2 RCA phono outputs. 
  • Purely passive device eliminates signal degradation caused by mains-born noise.
  • 6 inputs, 2 outputs.
  • 24 position volume control provides gain change from +4dB to -60 dB. 
  • Mute switch to select off at any volume setting.
  • DC coupled with no capacitor in the signal path for ultimate sound quality.
Frequency response: 8Hz-100kHz +/- 0.1dB
Maximum signal level: 4V RMS 8Hz; 10V RMS 20Hz
Maximum DC offset : 5mV. (For undistorted 8Hz)
Distortion: Less than 0.01% at 400Hz, 10V (2nd and 3rd harmonic only)
Input impedance is dependent upon the load impedance and gain setting. So, with a power amplifier having 20kohm input impedance (typical)
Impedance: At 0dB, input impedance is 20kohm 
At -10dB (normal listening) input impedance is 200k
Inputs: 6 pairs RCA phono sockets (gold plated)
Outputs: 2 pairs RCA phono sockets (gold plated)
Width: 127mm (5in)
Height:  45mm (1.8in) 
Depth:  305mm (12in) 
Weight:  1.5kg (3.3lb)
