Signature Two Phonostage
Fully discrete class A moving coil performance with infinite adjustment.
The Signature Two represents the definitive culmination of over two decades of dedicated phono-stage development. By eschewing op-amps and transformers in favour of an entirely discrete transistor signal path, it achieves a level of transparency and dynamic realism that remains faithful to the finest vinyl pressings.
Positioned as the highly flexible stablemate to the Signature One, this model is built for the enthusiast who values precise cartridge matching. Its design ensures that the delicate signals from low-output moving coils are amplified with exceptional linearity, providing a vast and stable soundstage without a hint of artificial coloration.
In use, the Signature Two is remarkably quiet, offering a black background that allows micro-details to emerge naturally. The sound is characteristically organic and fast, possessing the weight and authority required to bring complex musical performances to life with effortless ease.
Key Features
01
Discrete class A design
A four-stage circuit using custom transistors throughout, avoiding the compromises of monolithic op-amps.
02
Independent adjustment
Provides separate controls for gain (52dB to 72dB) and loading (32 ohms to 1100 ohms) for precise cartridge matching.
03
Passive RIAA equalisation
Constructed with low-distortion polypropylene capacitors and audiophile MELF resistors for accurate frequency correction.
04
Proprietary power regulation
Features a linear supply with dedicated discrete regulators for the sensitive first gain stage, ensuring independence from mains fluctuations.

Engineering Philosophy
The Signature Two is designed to be the ultimate conduit for moving coil signals. By utilising a four-stage architecture where each section is purpose-built, we have eliminated the need for global feedback. This results in an incredibly fast and accurate transient response, preserving the rhythmic integrity of the music.
Chapter 02
Manufacturing Process
Every unit is designed and built in the United Kingdom with a focus on signal path purity. The internal layout is meticulously routed to manage ground currents and prevent interaction between the high-gain stages, ensuring a level of noise immunity that allows the subtlest textures of a recording to remain undisturbed.

Listening Notes
This stage is celebrated for its clarity and lack of electronic footprint. Reviewers consistently note its ability to render complex music without confusion, maintaining a separation of instruments that feels entirely natural. It is an instrument designed to satisfy the most critical listener, regardless of the musical genre.
