Completely redefines what the preamplifier's can do in your system

The Wheel

The ultimate aim of the Quest is to create the perfect preamplifier to accompany the Rei and the cables lineup. With the Quest, it completes the loom between your source and pair of speakers. Setting out to push the boundary, it redefines how a preamplifier can contribute to the system and the ability to extract every bit of potential from both the recorded music and the music reproduction system.

During the inception of the project, we endlessly question the role of the preamplifier in an audio system, and constantly challenge whether a pre-amplifier is absolutely necessary in a system and what qualities the added stage can bring or may bring to the outcome. We begin with a fresh start to investigate the relationship between the source and the amplifier. Every section of the preamplifier has been looked at thoroughly to see how we can improve every single part and also what kind of synergy we can extract from them.


Behind industrial and electronic design of the Quest echos with the WestminsterLab tradition. Keeping unnecessary features and ornaments to the minimum and brings the purest musical and user experience to you.


No fancy colour display, UV meter or any distracting items. Prepare rediscovering your music.

Hybrid Grounding

The overall ground design and grounding scheme can hold a significant impact to the overall performance of the system, especially for tiny signals like the Quest handles. Tremendous effort has been put to design the grounding of the Quest and we have developed a new grounding scheme - Hybrid Grounding. Hybrid Grounding allows users to switch between two grounding modes on the fly so as to configure their Quest specifically for their system and look at the grounding scheme as a whole.

Compartmentation and Shielding

We have gone to the end of the world and taken extensive measures to protect the fragile signals going through the Quest. Many signal handling relays feature a soft start mechanism, sections within the unit are isolated and compartmented, making sure that the cross interference is minimised. For customers who want the best of the best, they can choose to purchase the extended carbon fibre option which adds another layer of carbon fibre shielding inside the unit.

Expandable Future

At the back of the unit, there are two slots where users can insert expansion modules in the future. These sockets are designed to provide flexibility to design modules to add more input functions to the unit. For now, there is a RCA input card, and in the future there may be a phono input card or even a digital input model.
