£834.00 – £967.00

Especially designed to isolate individual components such as CD players, turntables, DACs, preamplifiers, power amplifiers, computers and streamers from deleterious vibration.

The Seismic Isolation Platform includes a durable slim steel top plate that integrates unobtrusively under any hi-fi component.

The acoustically dead constrained-layer damped plate combined with a Seismic Load Cell™ attached to each corner is the ultimate combination to absorb and isolate unwanted vibration, including structural, air-borne and that generated by the hi-fi equipment.

Townshend Allegri+ Passive Preamplifier – Pure Sound, Unmatched Clarity
Elevate your audio experience with the Townshend Allegri+ Passive Preamplifier, a masterpiece of engineering that redefines transparency in high-fidelity sound. Priced at £2,400, this compact yet powerful device is the ultimate choice for discerning audiophiles who demand nothing less than perfection from their hi-fi systems. Say goodbye to noise, distortion, and compromise—say hello to music as it was meant to be heard.
Why Choose the Allegri+?
Unlike traditional preamps, the Allegri+ is a purely passive autotransformer design—no power supply, no active components, just unadulterated sound. Its state-of-the-art autotransformers, wound with Townshend’s proprietary Fractal-Wire™ and laminated with ultra-thin mu-metal, deliver astonishing resolution and transparency. From crystal-clear treble to deep, powerful bass, every note is rendered with breathtaking accuracy.
  • Six Input Options: Seamlessly switch between your sources with six gold-plated RCA inputs and a convenient 3.5mm front-panel jack.
  • Precision Volume Control: A 24-position volume control offers tailored intervals to suit any system, ensuring perfect loudness without sacrificing dynamics.
  • Impedance Mastery: Unlike conventional passive controllers, the Allegri+ matches the impedance of your source and amplifier, preserving every ounce of musical energy.
  • Silent Operation: With no capacitors in the signal path and a mute switch for instant quiet, it’s as pure as it gets.
The Sound of Nothing—Except Music
The Allegri+ doesn’t just amplify—it reveals. Experience a soundstage so open and detailed, you’ll hear nuances you never knew existed. It’s DC-coupled for zero signal degradation, and its sleek anodized aluminum chassis houses technology that outperforms preamps costing thousands more. Reviewers rave about its “uncoloured, open sound” and “astonishing transparency”—this is the preamp that lets your gear shine.
Perfect for Any System
Modern source components output around 2 volts with low impedance, and most power amps hit full stride at 1 volt. The Allegri+ bridges that gap effortlessly, eliminating the need for gain while maintaining full dynamics. Pair it with Townshend’s F1 Fractal™ Interconnects for the ultimate sonic synergy—because even one meter of lesser cable can dim its brilliance.
Key Features:
  • Inputs: 6x RCA stereo pairs, 1x 3.5mm jack
  • Outputs: 2x RCA stereo pairs
  • Frequency Response: 8Hz–100kHz (±0.1dB)
  • Distortion: Less than 0.01% at 400Hz, 10V
  • Finish: Elegant silver anodized aluminum
  • Warranty: 5 years of peace of mind
Hear the Difference Today
The Townshend Allegri+ isn’t just a preamp—it’s a revelation. Whether you’re spinning vinyl, streaming hi-res audio, or enjoying a CD, this passive marvel brings you closer to the artist’s vision. At £2,400, it’s an investment in sonic purity that outperforms active preamps at triple the price.

  • Ultra thin platform disappears under equipment
  • Enhances clarity across the frequency range
  • Delivers wider and deeper soundstages
  • Improves bass definition
  • Reduced muddiness and smear
  • Makes transients clearer

The Seismic Isolation Platform is available in three standard sizes:

Size 1 43x30cm (17×12″)

Size 2 48x35cm (19×14″)

Size 3 52x40cm (20.5×16″)

Platform working height is approximately 40mm (1.5″)

The Platform can be levelled by turning the adjustable Seismic Load Cell™.

It is important to specify the weight of your equipment when ordering. Bespoke platforms are available for any size or weight of audio equipment.Seismic Platforms are available with seven different weight range capacities, varying progressively from less than 1 kg up to 200kg.

The maximum load when using four ( 4) type “F” Load Cells is 200kg (440lb). For loads greater than this, simply add more Load Cells. Virtually any weight of equipment can be isolated.

Each Load Cell is screw adjustable in height to allow for out of balance loads where the centre of gravity of the component is not near its geometrical centre. If the level balance cannot be achieved, then it is suggested to use additional Seismic Pods positioned under the Platform as necessary, to balance the load.

For asymmetric components such as a valve (tube) amplifier with the transformers at the rear, different load capability Seismic Load Cells™ can be used to balance the load.

We suggest, for reasons of ease of set-up and loads that are not equally distributed, that consumers always select the stronger Load Cell where two values overlap in the graph below.

For example, when using four (4) type “C” Load Cells, the maximum supported weight should be equal to or less than 52.4 Kg.

Jason Kennedy reviews the Townshend Seismic Isolation Platform under the Rega RP6 Turntable, a Leema Antila CD Player & Naim UnitiLite Massive increase in stereo three dimensionality, sound is clearer” A degree of hardness has disappeared and left a stronger sense of timing. “Bass goes deeper” Voice has regained its full richness, Quite a transformation in truth, and one that you’d be hard pressed to replicate with any similarly priced upgrade. The Townshend Seismic Platform seems to be able to transform the potential of electronic components as well as, if not better than turntables. What is clear is that few hi fi components give their best without isolation and the platform delivers as much in a neat and effective package and comes highly recommended.”
