PSVANE Discussion & Impressions Thread

@perkri Hi！We have just reviewed the after-sales data for this product and found very few issues. It is likely that there was a problem during the transportation of this batch. Regardless, if your product is still within the warranty period, we will assist you with the after-sales service.

@milpai

If someone prefer a relatively warmer sound, the ART series is a good choice. Of course, this also depends on whether the amplifier it is paired with is suitable.

@no_regrets

Hi Don,

The products on AliExpress are sold by our distributors, while the products on our Amazon store are sold directly by Psvane official.

ACME tubes do not require secondary matching as all ACME products have excellent parameter consistency.

@knotscott The idea you're talking about is exactly how we started the Horizon series.😉

@benanders Your information is correct, and your understanding of the costs is accurate as well.😁

With fewer manufacturers, the price of upstream raw materials has increased due to reduced demand, which has also led to higher production costs for us.

@milpai 

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.

@knotscott Yes, our products on Amazon are priced per pair.

Thank you so much for your interest in our products!

We warmly welcome you to give them a try.😉

@trivema 

Your collection of amplifiers and tube-based audio equipment is truly impressive! You have the opportunity to experience a wide range of mainstream vacuum tube models. 

Currently, the Horizon Series is sold directly by us, the official PSVANE brand, on Amazon in the US. You can conveniently purchase the Horizon series there. 

Thank you for your interest!

@sps55n Greetings!

Regarding your concerns about the reliability of the KT150, the Horizon series features the latest coating technology and a more robust design structure. These improvements address the issues found in previous KT150 products. 

As for the different KT150 products you mentioned, currently, only the KT150-PTJ (KT150J) is still in production. This is our entry-level product, offering a warm and powerful sound. 

Therefore, we highly recommend you try our Horizon KT150. This model provides a more comprehensive sound, richer layers, and better longevity, as it is our latest product.😊

@hdm 

Firstly, in terms of product line hierarchy, the UK series you mentioned is Psvane's entry-level product, while the Horizon series is selected product.

In my opinion, I believe the EL34-UK has a full and natural sound with powerful bass, so your initial choice was excellent!

As i mentioned, Horizon series is ranked higher than the UK series because it incorporates a range of our latest technologies. 
Therefore, the sound quality has comprehensive improvements in detail and layering. I highly recommend you give it a try.😉

@dekay Hi! The Horizon series is currently only available for sale on Amazon in the United States.

@dwolek 

I apologize for the shortcomings in our previous after-sales policy. Our sales channels were too scattered in the past, leading to many situations we couldn't monitor properly. I sincerely apologize for this.

To address these issues, starting with the Horizon series, we have decided to manage our Amazon retail operations directly and fully adhere to the platform's after-sales policy to ensure the interests of our users are protected.

Regarding durability and quality concerns, our latest Horizon series incorporates new technologies, with enhanced bases and internal components. Combined with Amazon's after-sales policy, we hope our customers can purchase our products with confidence.

@milpai 

In our sample tests, the Horizon tubes did not show any quality issues after 200 hours of continuous use.

Regarding your question about the Horizon and ART series, both belong to our selected tier. The main difference between them lies in their sound characteristics, with the Horizon offering a more neutral sound.

@aniwolfe 

First of all, the KT88C is not our latest product, but based on our after-sales data, it is a reliable and stable product. You can use it with confidence. 
Regardless of the channel from which you purchased it, if you encounter any issues (as long as it is still within the warranty period), you can contact the dealer for warranty service. If you do not receive timely assistance, feel free to send me a private message here, and I will do my best to help you resolve the issue. 
This is the value of my presence here and my communication with everyone.

@rajugsw 

Thank you!

We do not have plans for the KT170 this year. 
May I ask which series of the KT150 you  listened to?

@dwolek Certainly. You can directly apply for a return or replacement through Amazon. However, please note that Amazon's application window is limited. If you are unable to find the application portal, you can send us a message, and we will manually process the refund for you.

@rajugsw 

That is KT150 of HIFI series.😁

@trivema Thank you for your inquiry. The Horizon series has a maximum rating of 480V, 100mA, and 40W dissipation.

@curiousjim Since you purchased a used item, may I kindly ask if you had a chance to check the quality to ensure everything was in good condition? Additionally, it might be helpful to contact the seller to inquire about the previous condition.

@jetter According to our warranty policy, tubes can be returned or exchanged within the warranty period. If you encounter any issues, we can provide assistance.

@curiousjim 

@jetter 

And we will also investigate the after-sales rate of tubes from Viva to identify the exact issues in the transportation or production process. 
We apologize for any inconvenience this has caused you.

@dogearedaudio 

6L6 and KT66 can be interchangeable in certain situations (depending on the amplifier you are using). Our Horizon series also includes the 6L6WGC-AT.

The bias voltage requirements for KT66 and 6L6 are different. When interchanging them, it is necessary to readjust the bias voltage to ensure the tubes operate within the correct range. If the bias voltage is incorrect, it may cause the tubes to overheat or distort.

@curiousjim 

Hi Jim,

May I kindly ask if you have already tried contacting the dealer for after-sales service?

If you are unable to receive support from the dealer within the warranty period, I would be happy to assist you in resolving any issues.

@chenry 

Thank you for your appreciation of our products!

To make purchasing and after-sales service more convenient for our customers, we have opened an official store on Amazon. This ensures a better and more reliable shopping experience for everyone.

@cey 

@benanders 

I can state with full responsibility that although we are both based in Changsha, HuNan province. PSVANE has no relationship with Shuguang at all.

PSVANE is a completely independent vacuum tube brand and factory, and we have been established for over ten years. We produce approximately 1.6 million vacuum tubes annually and employ over 300 staffs.

Regarding TJ FULLMUSIC: I can disclose that a few years ago, we acquired some of the assets of TJ FULLMUSIC in Tianjin, China. 

Additionally, as far as I know, Shuguang is entirely a state-owned enterprise in China, and at this level, we cannot have any relationship with Shuguang.😉

@cey Thank you for your kind words. 😄

I kindly suggest that you may try our newly launched HORIZON series 12AX7.

@cey Starting a business after leaving a company does not mean there will be any connection with the previous employer. PSVANE is entirely independent in its production lines, R&D, and personnel. It has no ties to Shuguang in terms of operations, management, technology, or finances.

@milpai I am also very much looking forward to customers sharing their personal experiences.😊

@curiousjim I recommend contacting VIVA TUBES to inquire about their after-sales support. If it doesn't work, I am very pleased to assist you directly. And if you have any questions regarding PSVANE or vacuum tubes, please do not hesitate to reach out to me at any time.

@cey 

1-YES，was independently found  by ex-peraonel. 
2-YES, and the EL34UK is a great match for the Marshall JCM800.

@mofimadness 

Thank you for your continuous support of PSVANE.
Yes, the Horizon series is our latest release.
This groundbreaking series is crafted to deliver "premium sound at an affordable price" to all our customers.

To achieve this, we’ve introduced the innovative HPC-T and HPC-X anode coating technologies, alongside new high-density ceramic tube base materials. We’ve also reinforced the internal structures in our mini tubes to ensure exceptional durability.

Every HORIZON series product undergoes rigorous quality control and burn-in testing to guarantee unmatched stability and reliability.

@cey 

No, we do not have KT66.

And there are no plans for manufacture within the next year either.

@audioquest4life 

Thank you for your suggestion. Our website is currently being revamped, and the information you’re looking for will be available once the new site launches in September.

Although the information isn’t published on the website yet, I’m happy to answer your questions. 
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.
The WE Series pays homage to the classic Western Electric sound.
The A Series is our true flagship, offering a neutral and well-rounded sound profile.
The main differences between the two series within each level lie in their sound styles.

Regarding the technologies and features of the HORIZON series:

1. Advanced Coating Technologies: The H series uses HPC-T and HPC-X coating technologies, significantly reducing signal distortion, ensuring stable output, and enhancing sound purity.
2. High-Quality Materials: Utilizes high-quality cross-class materials, extending lifespan and improving sound quality.
3. Rigorous Quality Assurance: Each vacuum tube undergoes a burn-in test for at least 24 hours before leaving the factory, ensuring stability and reliability.
4. Minimal Noise: The 12AX7-AT, 12AU7-AT, and 12AT7-AT tubes feature an improved internal structure design and extensive pre-burning process, significantly reducing noise and microphonics, ensuring exceptional performance.

@milpai

The sound signatures have some differences: the ART series is warmer, while the Horizon series is more neutral and natural. It's similar to the Sennheiser HD600 and HD650. Although the HD650 is more expensive, the biggest difference between them lies in their sound signatures.

In terms of lifespan, the Horizon mini tubes all adopt the latest internal reinforcement structure technology, which indeed results in a longer lifespan.

@facten

Currently, the PSVANE STORE on Amazon is our official store. We only sell the HORIZON and ACME series products in our official store.

@facten

The Acme series 805 tubes you see listed as shipped and sold by Psvane Direct are from our official store. For the 211, 300B, 845, 2A3, and 274B tubes, they are shipped and sold by Salience Hi Fi Audio, which also sells genuine Psvane products. 

Our official store ships from China using Fulfillment by Merchant (FBM) because the A series products are high-value items. Storing them in large quantities in Amazon warehouses has led to significant damage in the past. To prevent this, we now ship each tube individually from China, ensuring that every tube is tested at the factory before shipping.

The only difference between shipping from China and the US is the delivery time. 
When purchasing Acme tubes on Amazon, customers benefit from Amazon's convenient return and exchange process.

@facten

Salience purchases products from the official PSVANE source. We test the products before shipping them to Salience, but I am not sure if they conduct additional testing before their shipment.

@facten

Hello, what I explained earlier is no problem, but there is a logic specific to Amazon’s platform regarding third-party sellers.

You can understand it as we are the official direct seller, but there are also other third-party sellers. When I mentioned the PSVANE Store on Amazon, I was referring to our own direct selling identity, but it does not mean that all PSVANE products on Amazon are sold directly by us.

@no_regrets

Understood. I suggest you contact the dealer for a replacement. This issue might be caused by internal component loosening during long-distance shipping and multiple handlings.

Please rest assured, our Acme series has been sold for many years and has never caused any equipment damage.

@no_regrets

Hi Don,

May I ask which store you purchased from on AliExpress? AliExpress collects a deposit from sellers, so it is likely that you will receive an automatic refund once the seller receives the returned item.

If you are located in the United States, we would recommend purchasing from our store on Amazon in the future.

Kind regards

@no_regrets

Hi Don,

Based on the information you provided, the seller should be GD-PARTS Audio Store. As for the purchasing channels, you can choose the one you think offers the best price. All Acme series products currently sold on the market are genuine.

If you do not receive a refund after some time, please contact us. We will investigate and resolve the issue for you.

We are very sorry for the inconvenience caused to you.

@no_regrets

You’re welcome, and thank you for your trust in me.

@markmuse 

We regret to inform you that we currently have no plans.

@markmuse Thank you for your order! We hope you enjoy the listening experience!

@riparian 

OMG, I can’t believe Amazon would use an envelope for packaging! According to their original promise, this should have been placed in a box with proper padding. Thank God your items weren’t damaged. Thank you for informing us about this situation. We will seriously look into how to address this in future packaging. If your product gets damaged, please contact Amazon for a return promptly.

For our ACME products sold on Amazon, we ship them directly from China. Before shipping, we ensure they are packaged with sufficient strength and ample padding. Please rest assured.

@markmuse 

Our recommendation is to burn in the tubes for about 50 hours to allow them to stabilize. 
During this burn-in period, if you notice that the sound remains consistent without significant changes, it indicates that the tubes have reached a stable state. 
While we suggest 50 hours, it's not mandatory; some reviewers find that 4 hours are sufficient.

@ampus 

Yes. The burn-in test is a part of our quality control process. After a 24-hour burn-in test, we conduct another inspection to eliminate any tubes with quality issues.

@tksteingraber Sorry, I don't get your questions. Would you please make easier to understand ?

@tksteingraber 

1. The two Cossor tubes you mentioned are customized tubes. Besides retail, Psvane also manufactures tubes for many audio and musical instrument brands worldwide. Due to the differences in performance and application environments required by each brand, these products cannot be directly compared with our retail products. Moreover, we have confidentiality obligations to our OEM customers, so I am sorry that I cannot provide an accurate answer to this question. 
These tubes are currently discontinued, but distributors may still have stock for sale.

2. The Mark II you mentioned is part of the ART series and is currently still available for sale.

3. The Treasure z black glass you mentioned is part of the Treasure series, which is still available for sale. However, the Treasure series is a collaboration between us and distributors and is not part of our classification hierarchy.
