COSSOR vacuum tube, a model of British acoustic aesthetics

In the 1930s, as the founder of a generation of British sound, the British COSSOR Radio Factory was established. COSSOR's main products include a series of civilian vacuum tubes, as well as classical gramophones, radios and other products. The brilliance of the classic British sound kicked off and lasted for nearly half a century. Since the 1950s, COSSOR has successively cooperated with famous vacuum tube companies such as GEC and OSRAM in the UK, and has left too many well-known masterpieces.

In the global audio vacuum tube market in the 21st century, the main reason for PSVANE's recognition is its unique musical sense and rich musical expression. Even in the cost-effective product series, PSVANE does not give up the pursuit of sound quality. This time, the brand-new audio vacuum tube series authorized by COSSOR PSVANE also embodies PSVANE's craftsmanship spirit.

Compared with competing products at the same price, COSSOR vacuum tubes have leapfrog technology and a commendable sense of music. Compared with competing products with similar technology and manufacturing process, COSSOR vacuum tubes have a more friendly price.

"Born for Music" is the core product concept of PSVANE. With its blessing, COSSOR vacuum tubes also live up to expectations.

Carbon Crystal II" technology*

10 years ago, the PSVANE R&D team applied carbon crystal technology to audio vacuum tubes. Carbon crystal II technology has further improved the thermal conductivity on the basis of the previous work. The large dynamics are rock-solid, the tone is warm and mellow, and the sound background is dark. It also gives the COSSOR vacuum tube a sound texture close to vinyl.

Resonance optimization design

Harmful resonances have always been the natural enemy of hi-fi systems. The PSVANE R&D team comprehensively optimizes the resonance performance from multiple perspectives such as structural support, damping coefficients of different metal parts, welding position, glass bulb material and volume, and tries its best to maintain every detail and soft sound performance. The full frequency range of COSSOR vacuum tubes is superior in rich sound details, and the huge sound field and live atmosphere displayed when listening to large-scale symphony-type themes are even more unforgettable.

More emphasis on high current design

Electricity is the blood vessel of the sound system. The COSSOR vacuum tube has paid more attention to this at the beginning of its design. With the improvement and optimization of the electrical properties of the main materials, in addition to retaining the wonderful sound, it also has the sound characteristics of fullness, transparency, and texture. Among the price vacuum tubes, it is even more impressive in terms of sound control and other aspects.

Adhere to the aesthetics of British sound

Adhering to the tradition does not mean being conservative. Not only as an audio amplification component, the audio vacuum tube also carries aesthetic labels such as retro, classic, and human nature. As one of the main founders of British sound, COSSOR vacuum tubes have always been required to be as consistent as possible in terms of main materials, spray formulations and technological processes with those produced in the UK back then. All efforts are to restore the wonderful beauty of the last century. British sound quality.
