Hi-Fi Tubes - Best Sound for Music Lovers

The demands audiophile music lovers place on their high-end tube amplifiers couldn't be higher. Natural articulation, expansion, and three-dimensionality of sound determine the enjoyment of music. To equip top-quality tube amplifiers for premium applications optimally, we have assembled a large selection of special Hi-Fi tubes for audiophile listening pleasure. From NOS RCA driver tubes to powerful Kron Audio tube pairs, we offer high-quality tubes for great musical enjoyment.

Hi-Fi Tubes - Suitable Selection

As with instrumental amplifiers, selecting the right valve for top-end applications depends on two things: technical compatibility and listening experience. Since the enjoyment of music is a highly individual and subjective experience, selecting the right valve for one's own system primarily depends on personal taste.

We source our Hi-Fi valves from leading manufacturers and offer only high-quality products from GEC, KR Audio, Psvane, and RCA. This allows us to benefit from the experience of these companies and offer our customers high-quality and proven systems.

Our Selection: Preamp, Power Amp, and Rectifier Tubes

The internal structure of a premium-quality valve amplifier typically consists of a preamp and a power amp. Rectifier valves are also commonly used.

Preamp Valves

Our Hi-Fi preamp tubes are supplied by RCA and Psvane and form the core of our high-fidelity valves. From the simple but very good RCA 12DQ7 to the matched Psvane ACME 300B pair - our preamp tubes are equipped for all systems!

Power Amp Valves

Hi-Fi power amp tubes provide the necessary power to operate the speaker systems of a sound system. It is undeniable that these valves also have a major impact on the sound of the system. Therefore, we offer our customers a wide selection of power amp tubes, from the 211 Hi-Fi series from Psvane to the Ultra High Power pair of the Kron Audio T1610.

Rectifier Valves

Although rectifier tubes are rarely used today, their tonal influence is unmistakable. With Hi-Fi variants from Psvane, Kron, and GEC, we offer a high-quality selection to all fans of the technology!

Burn-in Time and Sound Development

Not only do instrumental amplifiers need to "break-in." The high stresses that arise inside a vacuum valve under load cause the material to work, which can lead to audible changes in sound, especially at the beginning. Many manufacturers specify a period of time needed to initialize the Hi-Fi valve. It is therefore essential to enjoy the initial listening impression but not consider it as the final result.

Only after a period of up to 100 operating hours - depending on the type and application - has the tube "broken in" and can unleash its full potential.

TAD - Hi-Fi is Our Passion

Since 1993, we have been assisting our customers with advice and experience regarding the operation and repair of tube amplifiers. Whether it's Cayin amplifiers, Marshall heads, or valve amplifiers for turntables: we support our customers in building and repairing all types. Our inventory of 650,000 parts, including Hi-Fi capacitors, sockets, and other components, offers the right part for every project, and our knowledgeable and passionate staff provide the necessary expertise - always at fair prices and with a love for music!
