About Us

Discover our story and approach to creating audio equipment.

Who we are

Stereo Valve Werke (SVW Audio) is a Polish manufacturer founded by two engineer-enthusiasts: Robert – a specialist in tube technology and analog circuits, and Jakub – PCB, enclosure, and digital solutions designer.

Our approach

We don't believe in half-measures. Every project starts from a blank slate – we design schematics, printed circuit boards, and enclosures from scratch. We don't use off-the-shelf solutions.

We rely on proven components (Vishay, Nichicon, Samwha) and custom-made enclosures. Assembly is done manually, with attention to every detail.

What we create

We specialize in tube and hybrid devices – from headphone amplifiers to phono preamplifiers. Each device is tested for sound quality, reliability, and aesthetic finish.

Besides manufacturing, we also offer audio equipment repair services, with particular focus on vintage and tube devices.

Why trust us

Full control – from idea to final product
No compromises – we don't take shortcuts
Individual approach – each device is tuned and tested
Transparency – we're clear about components and technologies used

If you're looking for equipment made with passion and engineering precision – you've come to the right place.

Technology Collaboration

PCBWay

PCBWay is a global provider of high-quality PCB manufacturing and prototyping services. As part of a limited collaboration, selected Stereo Valve Werke prototypes are developed with their support. This sponsorship allows us to focus on refining designs while ensuring reliable PCB production during the development phase. We appreciate PCBWay's support for independent hardware projects like ours.
