With the release of the Summit series, we are confident that we have reached the pinnacle. Our latest developed technologies and craftsmanship have elevated the fusion of technology and sound to an entirely new level. Join us as we explore the summit of perfection!

As a core power tube model in PSVANE’s flagship SUMMIT series, represents the brand’s ultimate pursuit of sonic expression and structural innovation in the field of high-power audio tubes, and represents the culmination of decades of technical expertise in preamp signal amplification.

Ancient vacuum tubes—do they still have the potential to breathe new life into sound? Is there a technological peak yet to be reached? This is a question we have long pondered and explored.

The PSVANE SUMMIT KT88 not only fully meets the demands of audio systems for power, control, and dynamic headroom, but also delivers a meticulously balanced tonal performance. By optimizing sense energy in the low-mid frequencies and the high definition, it offers a clear and impactful soundstage.

The PSVANE SUMMIT KT88 uses an HPC coating, an innovative multi-layer composite coating technology specifically designed by PSVANE to enhance the performance of vacuum tubes. It employs high-temperature stable materials, significantly improving the cathode’s electron emission efficiency.

Only the top 2-3% of tubes from each batch make it into the SUMMIT series, and they undergo a rigorous 30-hour burn-in test process to ensure that every tube you receive lives up to the SUMMIT name.

PSVANE is headquartered at Changsha Hengyang Electronics Co., Ltd. in Hunan Province, China. In 2024, PSVANE produced approximately 1.6 million vacuum tubes annually, employing a specialized production team of over 300 professionals.

The company’s products are used in high-end audio, musical instruments, medical fields, and other professional sectors. PSVANE is one of the world’s largest and most capable enterprises with full-scale design, R&D, production, and OEM capabilities for all types of vacuum tubes.
