The listeners were immediately aware of the lack of electronic hash, glare, hardness and artificiality. Instead we heard near magical transparency, exceptional bandwidth, tight control, fine clarity, wide dynamic range, excellent pace and timing, and deep, wide sound stages. Scores can become a little crazy when one encounters components that redefine sound quality, but I have to give this control unit a massive 235 under good source and load conditions.”

The Allegri+ is a breakthrough in design as much as ultra-linear, FETs, DSD, or the like. Fractal wire impedance control is hard to implement. No one has ever tried to do it before now, or even thought about trying. All I can say is the Allegri+ is a stunning marvel for our audio age and a bargain, too.”

Positive Feedback - Robert H. Levi

The Allegri+ is genuinely devoid of the characteristics and colourations that are found with the vast majority of preamplifiers… it gives it to you just the way it is and if you’re after maximum fidelity that’s the way it should be….I believe the Townshend Allegri+ represents incredible value for money in sound quality terms… it is capable of truly transcendent results… it warrants an Editor’s Choice.”
 

Jason Kennedy -The Ear

Something I’ve been looking at for months now. I’m currently using a dCS Bartok direct into dual power amps which means using the Bartok digital volume control. I admit, at lower volume levels, there is a hint of less clarity, and the Allegri+ could solve this.

A timeless icon of audio engineering,

A masterpiece of audio engineering, the Townshend Audio Allegri+ Preamplifier harnesses the holy trinity of performance—transparency, dynamics, and bandwidth—to redefine high-fidelity sound. Through years of trial and error, Max Townshend’s team perfected a passive autotransformer design with Fractal-Wire™, eliminating noise from active preamps to deliver a near-silent noise floor and “stunning transparency” that reveals every nuance, paired with 24 precise 1dB volume steps for dynamic precision and a wide bandwidth for an immersive soundstage, outshining preamps costing far more. “The preamp isn’t there—just pure, unadulterated sound.
 

Transparency: The Allegri+ offers exceptional clarity and transparency, removing noise and colourations that other preamps introduce. –

Dynamics: It provides a natural and dynamic sound, with crystal-clear highs and expansive bass, allowing music to sound uncoloured and authentic. – Effortlessness: Reviewers praise its ability to handle music effortlessly, making the listening experience engaging and emotionally resonant.

Bandwidth: The preamp boasts an extended bandwidth, with a broad and deep soundstage, and excels at reproducing fine details and larger dynamic swings. – Noise Floor: One key feature is its near-silent noise floor, which contributes to an uncluttered and immersive sound.

Transformer-Based Attenuation

The Townshend Allegri+ volume control stands out from other designs on the market due to its unique use of transformer-based attenuation rather than the more common resistor-based or potentiometer designs.

Unlike typical resistive volume controls, which can degrade the audio signal and alter impedance, the Allegri+ uses transformer-based attenuation to ensure no energy is lost. This leads to improved dynamics, detail, and tonal accuracy.

Fractal Advantage

The Townshend Allegri+ is notable for its use of Fractal™ wire technology in its transformers, which plays a key role in enhancing its audio performance. The fractal wire design significantly reduces internal resistance by an astonishing 12%, a significant advancement in transformer technology. This reduction in resistance leads to a more efficient signal transfer, allowing for clearer, more detailed sound reproduction. By minimizing energy loss and signal degradation, the Allegri+ ensures that the audio signal remains as true to the original recording as possible, delivering superior transparency, dynamics, and tonal accuracy. This technology sets it apart from conventional preamplifiers, making it highly sought after by audiophiles for its ability to bring out the finest details in music.

The 'Giant-Killing' Allegri +

Hailed as a “giant killer” by seasoned audiophiles, the Townshend Audio Allegri Reference passive preamplifier outshines pricier, overhyped rivals with its distortion-free sound, precise 24-step volume control, and unmatched clarity. Like a Ferrari’s flawless gearbox, this compact masterpiece delivers transparent, dynamic audio with crystal-clear highs, expansive bass, and a near-silent noise floor, ensuring an effortless, immersive soundstage that unleashes your hi-fi’s full potential.
 

Solving Imprecise Volume Steps

Conventional preamps often suffer from coarse volume steps, causing uneven transitions or loss of detail, especially at low levels. Max Townshend’s team spent years refining the Allegri+’s transformer-based passive volume control, achieving 24 precise 1dB steps using high-quality autotransformers, a significant improvement over the limited steps of traditional potentiometers. This ensures seamless volume adjustments, preserving dynamics for whisper-quiet or high-energy listening, making music feel effortless and engaging. “The Allegri+ offers precise control with 24 steps, allowing fine-tuning without audible stepping

Eliminating Noise with Fractal-Wire™ and Transformer Design

Active preamps introduce noise from power supplies, masking subtle musical details and adding unwanted coloration. Through years of trial and error, Townshend’s seasoned engineers perfected the Allegri+ Preamplifier’s passive autotransformer design paired with Fractal-Wire™, a proprietary copper treatment that minimizes losses, achieving a near-silent noise floor and delivering “stunning transparency” that reveals every nuance, outshining preamps costing far more. “It’s like the preamp isn’t there—just pure, unadulterated sound.

Masterful Transformer Design from Decades of Expertise


The secret to the Allegri+’s brilliance lies in its bespoke transformer design, crafted by Max Townshend’s team, whose decades of experience unravelled the complexities of preamp performance through relentless experimentation. Unlike conventional designs that compromise clarity, the Allegri+’s autotransformer, refined over years of trial and error, delivers distortion-free sound with a “holographic-like” soundstage, making it a bargain masterpiece that fulfills every audiophile’s quest for sonic purity. “For the price, it’s a giant killer, offering clarity that shames preamps ten times its cost

High Bandwidth and Low Distortion:

The autotransformer’s design ensures minimal phase shift and low distortion across a wide frequency range. Townshend’s specifications highlight a distortion level of less than 0.01% at 1 kHz, ensuring the signal remains pristine even at extreme frequencies.
Sonic Impact: The Allegri+ delivers extended bass and sparkling treble without roll-off or harshness. Jason Kennedy in The Ear (2019) described it as producing “transcendent results,” with bass that is “tight and controlled” and highs that are “crisp yet natural.”

Why This Technology Excels

 
The autotransformer with Fractal-Wire™ winding is compelling because it addresses the pitfalls of traditional passive preamps (e.g., loss of dynamics due to resistive attenuation) while avoiding the coloration of active preamps. Levi’s review is particularly vivid in linking the technology to its sonic outcome: the Allegri+ acts as a “window” to the music, removing veils and letting every detail through. This is especially effective when paired with transparent cables like the Townshend DCT 300, which shares similar cryogenic treatment for low distortion.

Why Choose Isolda Speaker Cables?


Most speaker cables in the audio industry overlook the science of transmission line theory, resulting in micro-reflections that smear and veil the purity of sound. These reflections bounce between the source and speaker, muddying the music you love. The Isolda DCT Speaker Cable eliminates this issue through its unique geometry, closely matching the impedance of your amplifier and speakers. The result? A crystal-clear soundstage, lifelike 3d imaging, and seismic bass that transforms your listening experience.
