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.

Townshend Audio Seismic Isolation Bars – Elevate Your Sound, Silence the Floor
Discover the ultimate upgrade for your audio system with the Townshend Audio Seismic Isolation Bars for Speakers and Subwoofers (starting at £750 per pair). Handcrafted in the UK, these innovative isolation bars sever the acoustic connection between your speakers and the floor, banishing unwanted vibrations that muddy your sound and disrupt your listening space. Whether you’re running floor-standing towers, stand-mounted monitors, or thunderous subwoofers, the Seismic Isolation Bars deliver a transformative clarity that lets your music breathe freely—priced for the serious audiophile who demands perfection.
Break the Acoustic Chain
Speakers don’t just project sound into the air—they transmit vibrations through the floor, creating a feedback loop that blurs bass, smears mids, and sends disturbances rippling through your home. The Seismic Isolation Bars put an end to this chaos. Designed to be used in pairs under any speaker type, each bar features a robust steel cross-piece with raised ends, supporting two Seismic Load Cells™. These highly compliant cells effectively “float” your speakers in the room, isolating them from floor-borne vibrations above 3Hz in all directions—up/down, left/right, and back/forth. The result? A cleaner, more focused soundstage that reveals every nuance of your music, untainted by structural interference.
Engineered for Sonic Freedom
The magic of the Seismic Isolation Bars lies in their Seismic Load Cells™, a Townshend innovation that combines extreme compliance with precision engineering. Suspended on these cells, your speakers become decoupled from the floor’s influence, allowing their drivers to move freely without the damping effect of surface integration. Bass tightens, mids gain transparency, and highs shimmer with detail—your system will sound more alive, more dynamic, and truer to the recording. Plus, by preventing vibration transmission downward, these bars double as a neighbor-friendly solution, keeping your audio bliss contained to your listening space.
Tailored to Your Setup
Versatility is key with the Seismic Isolation Bars, available in five weight-range capacities to suit any speaker or subwoofer:
  • Less than 5kg: Perfect for lightweight stand-mounts.
  • Up to 13.2kg: Ideal for medium-sized speakers (using four “B” Load Cells).
  • Up to 52.4kg: Great for larger floor-standers or subs (using four “C” Load Cells).
  • Up to 75kg+: Handles hefty systems with ease (using higher-capacity cells).
Each pair is meticulously tuned to support loads from featherweight monitors to massive subwoofers. For setups exceeding 30kg—or taller equipment over 1m with a high center of gravity—we recommend switching to Seismic Podiums for single-handed loads up to 75kg, ensuring stability and ease of use. When weights overlap in the capacity chart, opt for the stronger Load Cell for hassle-free setup and balanced performance—e.g., four “C” Load Cells support up to 52.4kg, including any base plate.
Simple Setup, Lasting Impact
Installation is straightforward: place a pair of Seismic Bars under your speaker or subwoofer, adjust for level, and let the Load Cells do the rest. Crafted from high-strength steel and finished with Townshend’s signature attention to detail, these bars are built to last, backed by a 5-year warranty. The subtle lift—just enough to decouple—won’t alter your room’s aesthetics, but the sonic improvement will be unmistakable. Audiophiles report “night-and-day” differences: tighter basslines, a wider soundstage, and a quieter background that lets every instrument shine.
Key Features:
  • Vibration Isolation: Blocks frequencies above 3Hz, severing floor connection.
  • Design: Steel cross-piece with two Seismic Load Cells™ per bar.
  • Weight Options: Five capacities from <5kg to over 75kg.
  • Applications: Floor-standing speakers, stand-mounts, and subwoofers.

Why Choose Seismic Isolation Bars?
The Townshend Audio Seismic Isolation Bars aren’t just an accessory—they’re a revelation. By floating your speakers above the floor’s influence, they unlock a level of clarity and dynamism that rivals upgrades costing thousands more. Perfect for any system, from modest hi-fi setups to high-end rigs, they offer a practical, affordable way to elevate your sound while keeping vibrations at bay. At £750 per pair and up, this is precision engineering that pays dividends in every note.
