@gordoninibiza Hello! Thank you very much for your support of our products. Regarding your question, the product lineup I posted earlier was based on last year’s structure. The Horizon series was our new release last year, while the Summit series was newly launched this June.
Therefore, after updating our product lineup this year, the order is now as follows:
For audio vacuum tubes, the hierarchy of our product line is as follows:
Basic:HIFI、UK
Selected:HORIZON、ART
Premium:WE、ACME、SUMMIT
ACME Series: our previous-generation flagship product line, built with the highest-grade materials and the most advanced technologies available in the earlier generation of vacuum-tube engineering. It delivers the most comprehensive and outstanding sound performance in its class.
The SUMMIT Series is a comprehensive upgrade over the ACME series.
The difference between the ACME and SUMMIT series is not limited to the selection grade. Technically, the entire SUMMIT series adopts PSVANE’s proprietary multi-layer HPC coating technology, which significantly improves electron emission efficiency, heat dissipation, and vacuum stability. This extends tube lifespan, reduces electrical loss, and results in a more transparent sound with tighter bass and clearer highs. Summit 845 also features a nationally patented composite anode structure that enhances thermal management and electron flow distribution, ensuring excellent linear performance even under high voltage and current conditions.
Our engineering team is passionately working to expand the Summit lineup, and we’re excited about what’s coming next. We just ask for a little more time, as we want every new model to deliver the level of performance and craftsmanship our community deserves.
