Main highlights

Main highlights

• •With the launch of the SUMMIT series, we are confident in declaring—we have reached the summit. Through our latest breakthroughs in vacuum tube manufacturing technology, we have pushed the boundaries of audio performance and engineering integration to an entirely new level. Join us and explore the summit of perfection.
• •The PSVANE SUMMIT series features our innovative HPC Coating, a proprietary multi-layer composite coating technology developed exclusively by PSVANE to enhance vacuum tube performance. Utilizing high-temperature-stable materials, this coating substantially increases cathode electron emission efficiency, extends tube lifespan, and ensures consistent gain performance.
• •The PSVANE SUMMIT 6SN7 builds on PSVANE’s extensive experience in dual-triode vacuum tube design, delivering balanced and natural frequency response, transparent tonal foundation, and extremely low noise floor. It further enhances linearity control and dynamic responsiveness, offering rich, expressive midrange, crystal-clear highs that are smooth yet never harsh, and seamless frequency transitions that flow like a gentle stream. This tube imparts a remarkable sense of spatiality and layering to any high-end audio system.
• •Each tube in the PSVANE SUMMIT series represents the finest quality from among all PSVANE vacuum tubes. Only the top 2–3% of tubes from each production batch—those that exhibit superior electrical performance and consistency—are selected for the SUMMIT designation.
• •24 months warranty；We have extended the warranty for our new SUMMIT Series, so please feel free to buy with confidence, and if there are any problems, you can contact us to take care of them.

Main highlights

• •CV181-AT in the PSVANE Horizon series use Increased-Density ceramics for the base to improve on low conductivity and stability. And due to the HPC-X anode coating technology, anode-power's improved, thereby increasing output power, it can also absorb excess gas, extending life span. It is double triode, used in voltage amplification circuit and it can be replaceed directly by standard 6SN7 tubes.
• •The CV181-AT features the Horizon series' exclusive HPC-X coating and a base made of a new material.
• •Under precise voltage and temperature control, each PSVANE vacuum tube must undergo at least 24 hours of burn-in test before leaving the factory, to ensure that every product delivered to you is stable and reliable.
• •The CV181-AT is known for its powerful output and exceptional low-frequency performance, offering a rich and deep sound quality. It presents a warm and full audio experience, showcasing profound musical expressiveness.
• •12 months warranty
