PSVANE Discussion & Impressions Thread

@psvane ,

Good to see you back. I was the first poster on this thread and wanted to really like your tubes. Unfortunately after 3-4 sets of tubes, I have given up. None of your tubes lasted beyond 1 year (approximately). Your tubes drove me to NOS tubes for good 😀.

@marco1 

Thank you very much for sharing your experience with us, and we sincerely appreciate your recognition of the sound performance of the Summit series.

Regarding the matching and reliability concerns you mentioned, we fully understand your worries and take all user feedback very seriously.

First, please allow me to apologize once again for the noise issue you encountered with the first pair of tubes. When shipping individual retail units, our products are sometimes subjected to rough handling during transit, which may cause slight internal component movement and result in noise. We truly appreciate that you informed us promptly and gave us the opportunity to replace your pair with a brand-new set that was carefully tested and strictly matched.

Secondly, it is true that in the past our tube-matching process was not as rigorous as it should have been. Historically, our products were mainly sold through dealers. Although we performed initial matching before sending tubes to our distributors, most dealers would conduct additional testing and perform stricter matching before delivering products to their customers. Because of that workflow, our own matching procedures were somewhat relaxed. However, we have already implemented targeted improvements in the second half of this year to correct this issue.

If any customer encounters mismatched tubes or microphonics, they may now contact us directly to begin the warranty or after-sales process. We will replace the tubes with a new pair that has undergone strict testing and precise matching. This is also why we now offer a 24-month warranty for our high-end products sold directly through our store.

In addition, we have significantly strengthened our quality-control inspection rate during production, applying even higher standards to flagship lines such as the Summit series.

These measures have already resulted in substantial improvements over the past few months, and the stable performance of your replacement pair and the second pair you purchased reflects the progress of these upgrades.

We are truly grateful for your candid feedback—it is extremely valuable to us as we continue to refine and enhance the quality of our products. If you have any further questions or need assistance in the future, please feel free to contact me at any time. 

Thank you again for your trust and continued support.

@psvane  Melody please see the email I just sent to you at [email protected].  

@marco1 Sure. This after-sales mailbox is managed by my colleague. He is currently traveling for business, but I have asked him to review your message as soon as possible and get back to you shortly.

Hello Melody,

A while ago you posted the following on here ;

For audio vacuum tubes, the hierarchy of our product line is as follows:
Basic：HIFI、UK
Selected：HORIZON、ART
Premium：WE、ACME

The HORIZON Series is our latest line, featuring a more neutral sound compared to the Art Series and incorporating the latest technologies, such as HPC coating.

In terms of quality, our Horizon 12 series （12AU7、12AX7、12BH7） uses the latest internal reinforcement technology, resulting in improved durability.

I just pulled the trigger and bought a quad set of Summum KT88's from your company.. Where is the Summum serie located in that overview and why was it left out ?? 

Also why no KT120 and 150 tubes in the Summum series ??
