Allegri+
BREATH LIFE INTO YOUR MUSIC

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 your 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.

A real improvement of focus @ the top end. Even the bass is tighter. Huge change in the soundstage, The system has almost gone from stereo to surround sound. The Dusty in Memphis album, female vocals, full orchestra, especially show how the individual instruments are separated. It's quite possible to identify which bit of the cymbal the drummer is hitting. Pet Sounds of course uses every instrument in the book. Bass harmonicas, tambourines, and the vocals are just so separated & tight. Porcupine Tree, beautifully produced & pressed vinyl. Every instrument inhabits a different piece of the soundscape. Strip the Soul is just exquisite. I'm sure as they bed in, the Townshend's will get better still, but... so far it's love at first sight. Always loved the 989's but these supertweeters have taken them to a whole new level.

We sat down and i played one of my all time favorites Neil Young Comes a Time i now this album very well but not heard it like this before, the attack of the guitars, the extra resolution and bite of the guitars was nothing short of amazing, there was more snap to the drum beat, the top end is so much more realistic and enjoyable, while the mid range has gained resolution and body, the vocals are very natural sounding but also revealing, the bass seems to have improved, there is definitely more of it its early days but I'm keeping them and i am very happy with level 3, my speakers are Soundlabs Dynastats,

Lossless on the MacBook, DAB, Cd and analogue, vinyl and tape cassette all benefit from a fuller more emotional sound. Science is great, and will one day crack cancer and HIV but it struggles to quantify certain things in life and one of those things is emotion. I'm sure my hearing doesn't extend much above 16kHz or so and yet the super tweeters work and work well for me. I think transients, atmosphere, detail, attack and sustain all benefit as does timbre between instruments, sounds and especially vocals within the hearing range due to less distortion, less smearing and better definition at frequency extremes. Definitely not snake oil in my opinion.. ..A worthwhile investment and I will not be returning them or selling them on. Many Thanks Toni and keep the music musical..
