Overview

New Allegri autotransformer passive preamplifier from Townshend Audio is designed to provide ultimate signal transparency in high-end high fidelity systems.

The Allegri Autotransformer Passive Stereo Preamplifier is a high fidelity line level control centre that selects 6 inputs, adjusts gain and provides two outputs. It is a cut down version of the amazing Townshend Audio Glastonbury Pre 1 Autotransformer Preamp.  The Allegri preamp has almost the same sound as the Glastonbury Pre 1, but with no remote control, mono, mute, -10dB, +1dB, balanced operation, or AC coupling.

At the heart of the preamplifier designs is Townshend Audio’s new 24-tap Fractal-Wire™ wound autotransformer with 80% nickel mu-metal laminations for ultimate performance. All internal signal connections are by Fractal-Wire ™. As the Allegri preamps are purely passive devices there is no mains-born noise degradation. This, when combined with Fractal-Wire ™, results in the most accurate, uncoloured and open-sounding preamplifier possible – with astonishing transparency and resolution of fine detail.

There are 6 RCA phono line level inputs and two sets of phono stereo outputs.

Input selection is by manual control using the rotary selector knob on the left of the fascia.

Volume control is by a 24-position rotary switch divided into suitably chosen increments to provide a control range from +4dB to -60 dB and then mute.

As the Allegri preamp is DC coupled, so it is important that there is no DC offset on an input as distortion may occur. With the volume control set at 0 dB, the signal is connected directly from the input to the output.

The bright anodised aluminium metal case of the Allegri preamp is connected to the internal star earthing point of the signal ground to prevent hum.

Description

After 40 years of research encompassing all styles of amplification – including discrete transistor (bipolar & FET), integrated circuit valve (tube) and digital – we have found that all active implementations inevitably cause a slight veiling, noise and detail loss. Furthermore all volume controls – potentiometers (carbon, plastic film and cermet), switched resistor, optical and digital – similarly cause varying degrees of veiling and detail loss. Conventional  transformer volume controls are excellent, but it is very difficult to achieve a flat frequency response at all volume settings due to the stray capacitance reacting with the unterminated coil sections. The claim that transformer controls allow for balanced operation is only partly true as the circuit cannot truly be balanced due to asymmetry in the configuration.

By far the best solution is the autotransformer control which provides virtually zero noise, optimum impedance matching and up to 4dB of gain. Add to this Townshend Audio’s radical new (and proprietary) Fractal-Wire™ and the results are truly astonishing. Sound is clear, powerful, engaging, amazingly smooth and highly detailed. When set at 0 dB gain, the input is connected directly to the output with a single wire, so there is nothing in the way to change the sound. When the autotransformer is removed from the circuit (in the 0 dB case) there is no change in the sound whatsoever. This leads us to the conclusion that the Allegri Pre is truly “The closest approach to a straight wire with gain”. Substitute transformers wound with regular copper, silver or even DCT copper wire and the sound degrades with the addition of the transformer. But not so with the Fractal-Wire™ wound autotransformer. It is acoustically invisible! When laminated with the best ultra-thin 80% nickel laminations Townshend Audio’s autotransformer is, we feel, the ideal high fidelity component.

The 8th Annual Positive Feedback Online’s Writers’ Choice Awards for 2011 – The Best of the Best!

The Townshend Rock 7 Turntable has been my reference for over a year now, well before it started receiving attention in the U.S. audio press and mentions at many audiophile shows. I’ve sat down to write a review of this turntable several times over the last year, but I was forced to stop due to continuing changes in my reference system, involving the turntable or other components. Each change resulted in better and better sound enabled by the transparency of the Rock 7. A full review is forthcoming but I didn’t want to wait another year before giving this special turntable the recognition it deserves. The Rock 7 ranks with other turntables that cost $10K or more yet has a list price of about $3000 (without tonearm). Think of all the extra LPs you could buy for this difference! The Rock 7 has a unique suspension system that effectively isolates the turntable from outside disturbances, but its most noteworthy feature is the amazing “trough”, filled with damping fluid, that the tonearm headshell floats in. Damping provided by the trough smooths the bass response and controls other resonances in the cartridge/tonearm system that muddy the sound. Music through the Rock 7 emanates from a dead silent background and the action of the trough sharpens transients and lifts veils that otherwise obscure inner detail. The result is that music literally explodes from the groove and provides a sense of musical flow that I was never aware of before. Whether you have a $100 cartridge or a $5000 cartridge the Rock 7 will get the best out of it. It requires some tinkering to sound its best but worth the effort. Highest recommendation!

November, 2011 — Rafael Todes

To extend high-frequency reproduction to 100kHz seems batty, but says Jimmy Hughes, Townshend’s Super Tweeter is supersonic

The case for subwoofers is fairly easy to make. Most loudspeakers are limited in terms of size and this leads to restricted bass depth. Very few can reproduce frequencies much deeper than 30Hz (and many don’t even get that far), so there’s an obvious need for something to reproduce those lower octaves.

At the opposite end of the spectrum, virtually all modem speakers can reproduce high frequencies well beyond the range of human hearing-reckoned to be about 20kHz. Alas, few listeners the wrong side of 20 can hear as high as 20kHz. As for those of us the wrong side of 50 -well, we’re lucky if we can hear up to 15kHz! It gets worse. With most of us listening to music from CD, bandwidth is limited to about 19kHz. So, why invest in super tweeters that extend the upper frequencies out beyond 30kHz, when the recordings themselves have no high frequencies to exploit this and our ears can’t hear that high anyway?

The logic of the above seems irrefutable. Yet regardless of such ‘logic’, Townshend Maximum Super Tweeters are capable of having a profound effect on sound quality-and not necessarily in ways you might expect or predict. They’re Ribbon designs that behave like a subwoofer for the treble-influencing the sound in strange ways. Now you might expect a set of super tweeters to increase sharpness and give the sound greater upper-frequency immediacy and impact. This it does, but-and here’s where it gets a bit scary-you also notice improvements in apparent bass depth, along with increased lower-frequency tightness and control. Amazing! Subjectively, it’s akin to the way a good subwoofer makes the treble seems smoother and more ‘airy’, increasing the impression of 30 spacious depth and tonal richness. Although you’re only bolstering the lowest frequencies, the improvement seems to come in the midband and treble areas.

In much the same way, a good super tweeter seems to give you a tighter; cleaner bass, with reduced boom and overhang. Yet, turn off your main speakers and listen only to what ti1e super tweeter’s are doing-the noises they’re actually making -and it seems incredible that it could be making this sort of difference. One of the key aspects of getting great results from a subwoofer is-don’t have it up too loud. When you first get a sub, there’s a tendency to adjust it so its contribution is ‘obvious’. But paradoxically, subs produce their most profound effects when their presence is subliminal. You should only notice a sub when it’s switched off.

It’s exactly the same with a super tweeter; you need very little. Indeed, it’s been our experience (going back more than twenty years) that the less you have, the more profound the overall effect on sound quality becomes. We always use our Townshend Super Tweeters with them set to ’1′, and often wish there was a lower setting.

Discretion pays

The question is -how and why do super tweeters (and subs) contribute so much, yet (apparently) seem to do so little? In our view, it’s to do with being able to move air at sub-sonic and supersonic frequencies, making it easier for frequencies in the audible range to couple-better to the air. By setting the air in motion at extremely high or low frequencies, you help the drive units to move the air in the middle-frequency areas where the bulk of the sound is. Imagine a sharp blade trying to cut through something stiff. If you were to vibrate it at supersonic frequencies, it would cut more efficiently.

For this reason, you don’t actually have to ‘hear’ the contribution made by your super tweeters to notice the effect they have on the overall sound. Indeed, if the contribution is too strong, the result is counter-productive – the sound becomes messy and harsh, with excessive high-frequency emphasis. When a super tweeter seamlessly integrates, you get a focused quality of sound that has an innate clarity, while also displaying a spacious airy quality that creates holographic 3D ‘out of the boxes’ stereo imagery. Transients have increased attack, yet the treble itself is effortlessly smooth and open. Given that most loudspeakers are more obviously deficient at the extreme low-frequency end of the spectrum, a good subwoofer probably gives you a bigger bang for your buck. But a super tweeter like Townshend’s Maximum is likewise capable of adding an extra dimension that has to be heard to be believed.

Townshend Maximum Super Tweeters are capable of having a profound effect on sound quality -and not necessarily in ways you might expect or predict
