Lewis CaliburnFEEL FLOWS AUDIO has been appointed the official UK distributor of Ray Tubes, a premium vacuum tube brand. Musicians, hi-fi enthusiasts and sound engineers across the UK can now access Ray Tubes’ meticulously curated range through Feel Flows Audio Collective’s select resellers.
Ray Tubes, based in Oakland, California, was founded by audio engineers and musicians to address the challenges of the modern vacuum valve market. Their solution? Classic tone with modern reliability. Each valve is handpicked and rigorously tested, ensuring consistent quality, low noise and maximum reliability.
For years, audiophiles and musicians have sought New Old Stock (NOS) valves, but these can be rare, expensive and inconsistent. Ray Tubes provides a modern alternative: brand-new, hand-selected and extensively tested valves that deliver vintage sound without the risks, says the manufacturer.
Each valve undergoes a 24-hour burn-in period, high-intensity performance testing, and screening for microphonics, noise, gain and conductance, ensuring only the best reach customers.
Ray Tubes offers three distinct tiers to cater to different needs and budgets:
- CORE Series – Starting from £34.99
Reliable, high-quality valves that meet the needs of musicians, engineers and audio professionals looking for dependable performance at an accessible price.
- SELECT Series – Starting from £133.99
A step up in quality, these valves are individually tested and matched for enhanced consistency and sonic performance.
- RESERVE Series – Starting from £347.99
The highest grade of vacuum valves, carefully selected from the best available stock. These are said to ensure a refined sound quality for professional studios and audiophiles seeking the pinnacle of valve performance.
The Rise of ‘Tube Rolling’
The growing trend of ‘tube rolling’—the practice of swapping out vacuum valves in audio equipment to customise and refine sound—has gained traction among musicians and audiophiles.
Ray Tubes offers a solution for those looking to experiment with different valve characteristics, allowing users to fine-tune their amplifiers, preamps and hi-fi systems to achieve their desired sonic signature. With Ray Tubes now available in the UK, enthusiasts can access a reliable source of premium valves without the uncertainty of vintage alternatives.
“We’re excited to bring Ray Tubes to the UK,” says Greg Chapman, Founder of FEEL FLOWS. “High-quality valves are essential for preserving analogue warmth and depth. Ray Tubes offers the vintage character without the hassle of unreliable, ageing stock. Musicians, audiophiles, and engineers will appreciate the care and expertise behind every valve.
“Ray Tubes is a natural fit for FEEL FLOWS – Audio Collective. Alongside JICO and BonaWatt, we’re curating a selection of premium products that enhance the audio experience. Whether a stylus, power supply, or valve, we focus on exceptional craftsmanship that elevates sound reproduction.”
Ray Tubes are now available for purchase in the UK via FEEL FLOWS AUDIO select UK retailers.
