True high-end audio can be more accessible without sacrificing performance
The Omne is a all-in-one solution redefines integrated amplification by delivering reference-level performance in a compact, elegant package with just a height of less than 11cm.
The Omne represents the culmination of WestminsterLab’s proprietary technologies, including its signature Class-A circuitry and fully balanced architecture. Engineered without compromise over several years and through multiple iterations, the amplifier achieves astonishing sonic performance and a profound understanding of the elegance of music reproduction.
The Omne embodies this philosophy – it eliminates the traditional compromises of integrated amplifiers while preserving the emotional connection that only the finest separate systems can deliver.
Pure Class A
Power and Precision: Delivers 50 watts per channel of pure Class-A power into 8 ohms (100 watts into 4 ohms, 200 watts into 2 ohms) with a peak current output of 12A, utilising WestminsterLab’s proven Class-A topology. The fully symmetrical and balanced circuit ensures the Omne retains the classic WestminsterLab sonic signature.
Matching transistors is a well-known practice in amplifier design and manufacturing, but WestminsterLab takes a distinctly different approach. Going beyond the norm, not only are the transistors meticulously matched within an impressive 1% tolerance, but the matching and pairing process extends across multiple working points of the curve.
To ensure utmost reliability and performance, these matched transistors are rigorously stress-tested for hours under extensive loads. This meticulous testing and matching methodology is one of the key reasons why the Omne amplifier can deliver an astounding 50 watts of Class A power in such a compact package.
Engineering Solutions
The Omne power amplifier from WestminsterLab operates in pure Class A throughout all stages—a hallmark of our design philosophy that delivers exceptionally clean, ultra-low-distortion audio signals for unparalleled sonic purity and transparency.
While this approach yields profound musical insight and naturalness, it also generates substantial heat.
To master this challenge without compromise, we conducted extensive thermal simulations and engineering refinements. Each heatsink is precision-machined from a single solid block of high-grade aluminum, optimizing thermal conductivity and surface area for superior dissipation efficiency.
This meticulous, single-block construction—combined with our proprietary circuit topology—ensures the Omne maintains optimal operating temperatures, delivering consistent, reliable performance and long-term stability even during extended listening sessions.
Two tricks pony
Inherited from the acclaimed Quest pre-amplifier, the Omne utilizes the same architecture and schematic as its larger sibling. With a gain of just 6 dB and fewer than components in the signal path, the musical signal remains as and original as possible.
With the built-in pre-out, the Omne be paired with an extra pair of Rei to enable horizontal bi-amping with two sets of speaker cables for with dual binding posts. This ensures the scalability and upgradability of the system in the future.
Enhanced comfort features
With the new in-house Audio Controller, we have integrated many highly requested comfort features. The screen offers different operating modes with dimming and auto-off, delayed 12V trigger outputs, and for the first time in WestminsterLab, specific input out of the five can be chosen as a home-theater bypass. This makes the Omne one of the best integrated amplifiers for home entertainment system.
The power supply for optional modules now operates on a “power-on-demand” basis. Modules are powered only when their input is selected, reducing idle noise and improving overall power efficiency. When used with an optical, the optical element is switched off when not in use extending the life of the cartridge.
Full Linear power supplies
Having the purist power is fundamental to the WestminsterLab experience. Despite its compact size, the Omne houses four highly efficient O-core transformers in the lower compartment and 18 individual rails of separate linear power supplies for each section.
Even the control microprocessor and display have their own dedicated linear power supply to minimise noise. The pre-amplifier and power amplifier sections have completely independent power control, maintaining full audio performance when the unit is used solely as a pre-amplifier.
Less is More
The Omne’s minimalist aesthetic belies its sophisticated engineering. Its chassis, machined from multiple solid billets of aircraft-grade aluminium, provides exceptional structural rigidity and effective heat dissipation. The front panel features only a discreet display, maintaining WestminsterLab’s signature understated elegance.
For the first time, the Omne is available in silver or black analodised finishes.
