For Immediate News Release: Grant Fidelity will discontinue the entire Psvane line as of 8pm MST, Feb 7th, 2021

After over a decade of marketing Psvane tube brand from its ground zero back in 2009 when they just split off from the state-owned Shuguang tube factory in China, Grant Fidelity have made the decision to discontinue the ENTIRE LINE of Psvane branded vacuum tubes, effective 8pm Mountain Standard Time, Sunday, Feb 7th, 2021.

WHY?

When one supplier tries to restrict their business partner from doing business with another supplier, common sense is that the act is often derived from the fear of losing its existing and future market share. 

What can cause one brand losing market share to another new comer? It is often due to its products losing competitiveness on the market – either quality, or price, or both. 

No one will waste their breath to suppress another supplier who demonstrates no threat at all – especially when for tube reselling business, it is common practice for a reseller to carry multiple tube brands at the same time to provide a range of options to their customers. 

Psvane has been in process of transitioning from supplying for high end tube audio only to include the mass guitar amp consumer market. This transition, we firmly believe, will compromise its high end vacuum tubes quality control. As a matter of fact, we had seen decline of the tube re-testing results of the Psvane stock we have received over the time leading up to this current event, despite of our specified screening parameters. The confirmed test results decline is our main reason to seek Linlai™ brand as additional supplier to maintain our top quality commitment for our high end clientele. 

Psvane brand made it clear to Grant Fidelity that Psvane are OK with Grant Fidelity to carry any OTHER brands of tubes originated from China, Russia or other European origins EXCEPT Linlai™ brand due to their ‘personal grudges’ (related to financial interests of how to divide the profit while they were all still with Psvane) with the owners behind the Linlai™ brand. Grant Fidelity is simply NOT allowed to do business with Linlai brand and Psvane brand at the same time.

From Grant Fidelity’s perspective, this dictation from Psvane on whom Grant Fidelity can, or cannot, do business with is absolutely unprofessional and unacceptable. It is a form of supply chain bully in our opinion. The conflicts between Psvane and Linlai shareholders are their internal matters. Grant Fidelity will not tolerate to be forced into a position to pick sides on such internal matters, and certainly will not risk our own inventory supply & quality with it. 

It is Grant Fidelity’s absolute principle to ALWAYS operate as an independent business and thrive to hold our high level business ethics and standards. Grant Fidelity work for our customers by providing quality products, at their deserved fair price, and with our best possible service. Grant Fidelity do NOT bend to the interest of any particular tube suppliers, period. 

Here is the run-down of the events for those who are curious and care to know:

Psvane act #1: In November 2020, we received written communication from Psvane’s top manager expressing ‘concerns’ of Grant Fidelity carrying their direct competitor – Linlai™ branded vacuum tubes. (If you have read our post about ‘Who is Linlai™‘, you will understand the owners of Linlai™ Tube factory used to be a core part of Psvane team, and exited Psvane due to irreconcilable disagreement on profit sharing resulted from Psvane’s growth. )

Grant Fidelity response #1: Our business is to serve our worldwide customers. Offering product varieties to our customer is our legitimate independent business decision. We expressed our concerns that the action of Psvane trying to interfere free market competition by restricting us from carrying their competition’s products, may not be legit in western business context and we are not willing to participate such a controversial act.

Psvane soon-to-follow act #2: Unilaterally dropped Grant Fidelity’s recognition as ‘top level reseller’ and raised our purchase cost by a ‘very significant’ percentage. (What’s the logic behind this? To revenge because Grant Fidelity didn’t bother to obtain their approval to expand our own product offerings with their competitor’s brand?? )

Grant Fidelity response #2: We agreed to the significant price increase, and plan to adjust our Psvane product mix to focus more on high end tubes, and less on mid-level products to reduce the impact of cost increase, of course all on condition that the high end tubes must come with actual high quality. 

Psvane immediate act #3: Unilaterally announced to STOP offering tube ‘selection & screening service’, with the tube testing equipment that is owned by Grant Fidelity, provided and located at Psvane factory since 2009 (Psvane’s beginning of operation) till now, 2021. (What’s the logic of this act? Providing Grant Fidelity non-selected mixed quality of tubes, including those we have clearly set criteria to reject for the past decade, so that Grant Fidelity’s reputation will drop to sell ‘Chinese crap’ as some angry customers have expressed online, when they got sub-quality tubes from Chinese vendors?? )

FYI, in the past 12 months, Grant Fidelity have returned 161 tubes (valued approximately US $20,000+) from the Psvane factory deliveries, EVEN AFTER the screening at the tube factory with our provided test equipment, and AFTER we paid a price premium for the screening and selection service. That is nearly every other day we have identified a defective tube from the supply of ‘so called screened’ Psvane tubes. In the past decade, we have returned thousands of defective tubes all together to the Psvane factory.

Grant Fidelity response #3: We are immediately collecting our valued $5000+ tube testing equipment from Psvane tube factory, rather than leaving it there to collect dust and serve NO quality control purpose it was meant to for us.

Psvane immediate act #4: Sending a written notice to us to request us to STOP selling Psvane branded tubes all together, with reason as ‘We Psvane don’t want our Psvane products to be compared with Linlai™ tubes’.

Grant Fidelity response #4: We refuse to be cyber-censored. Grant Fidelity is NOT a puppet to any supplier. And yes, we indeed found the quality deterioration of Psvane ACME series test results vs. Linlai Global Elite series in the past months when we had both in our inventory, before the current Psvane discontinuation event. Many inferior quality Psvane ACME tubes were mixed into our inbound Psvane factory shipment even after we paid for price premiums. There is also event that Psvane refuses to acknowledge ‘red plating’ is a potential quality problem for the ACME hybrid plate design. 

After these 4 rounds of back and forth, I, as owner of Grant Fidelity, have come to clear conclusion that, we, Grant Fidelity, can no longer do business with Psvane. The business interaction with Psvane is no longer acceptable to what we are accustomed to in western business practice. Grant Fidelity will NOT be forced by anyone to limit our supplier to a specific brand only, plus quality dictated by such a brand – It will put our very own hard-earned business reputation at great risk from a Chinese supplier, who apparently do not understand how to deal with competition in a positive manner, and accept the fact of a failed partnership with their ex business partners is their own internal matter, not ours. In our opinion, Psvane’s right action should be focusing on improving products to maintain competitive edge to continue winning new customers. There is nothing to fear from healthy competition, if what Psvane offered is indeed preferred by the market. The very act of Psvane’s attempt to control us is the exact proof that Psvane themselves are lack of confidence in their own products in coming competition.

What NEXT?

Starting immediately as of Jan 26th 8pm Mountain Standard Time, 2021, we are putting a ‘pause’ on all outbound order shipping, when we count inventories to get ready to return ALL Psvane branded tubes back to Psvane factory. The shipping pause will be until Feb 6th, 2021.

From 8pm MST Jan 26th to 8pm MST Feb 7th, customers may still place online orders with us for Psvane tubes that we have in stock and only for those we deem quality meet our criteria. This is to allow customers to have final window of time to purchase Grant Fidelity approved quality tubes. All orders (including ALL brands of tubes, not just Psvane) placed during ‘pause’ time will be packed and shipped by end of Monday Feb 8th, 2021. If any orders are found not possible to be fulfilled due to quality issues we identify at packing phase, you will receive full refund by end of Feb 8th, 2021.

Online orders for ALL Psvane tubes will be PERMANENTLY CLOSED as of Feb 7th 8pm MST, 2021. We will cease to resell any Psvane tubes as of that cut off time.

All past Psvane tube orders and new Psvane tube orders fulfilled by Feb 8th, 2021 will have our tube warranty still honored in the form of either refund (minus shipping cost), or credit to replace with other brands of tubes of buyers’ choice.

We are rolling out more Linlai™ branded tubes VERY SOON- specifically, [Linlai™ Global] branded tubes that Linlai™ factory has embraced with production and quality screening to western standard, but not ‘just another Chinese tube brand’. You will see more [Linlai™ Global] tubes added to our website in the next few weeks. You can also learn more about this new brand from [Linlai™ Global] official English website.

 

The final words:

Hope this post has answered all the possible guessing and gossiping of why Grant Fidelity cease to resell the entire Psvane line of products. Now you have the entire drama scenes 🙂

All GF Special Edition tubes and Shuguang Treasure tubes will NOT be affected by this event and availability as usual as seen on the website.

Happy Listening,

And enjoy our precious freedom of choice, plus freedom of expressing opinions without any form of online offline censorship,

Rachel @ Grant Fidelity

Hear what the cable pro said about [Linlai™ Global] E-845….. ‘real keepers!’

Eric D. from France is an industry pro specialized in ultra high end cabling. His audition skills are professional and field proven, and here is what he said about after owning a pair of [Linlai™ Global] E-845 top grade tubes:

“The Linlai E-845s are very nicely built. You can tell by looking inside
the glass tube that they are manufactured with care. When brand new,
they performed nicely, but it was after about 120 to 150 hours that they
really came alive. They really need that burn-in time to reveal their
full potential. I’m not the patient type, but this time I was glad I
waited.

All the qualities the best 845s are renowned for are there. Let’s talk about dynamics first : a bit timid during the burn-in time, dynamics become quite exceptional after 100hrs and when tubes and amp reach their optimal operating temperature. They are extremely fast, with lots of impact and speed, speed and more speed. Extension in the bass is quite impressive and treble is exactly what you expect : not a trace of harshness but lots of details. Midrange is just exceptional, voices come alive to a point that I’ve very rarely experienced before. The timbres of acoustic instrument are very real, and that is quite obvious on violin or cello.

Soundstaging is outstanding, both in depth, width and accuracy. And there’s air between the instruments, something you can only hear when you are in the presence of real high-end gear. Pitch-black silence is another telltale sign of that.

On rock or blues, you can easily identify what guitar or amp is being played. A Strat sounds like a Strat, and there’s no mistaking a Les Paul or a Tele for anything else.

Comparing them to a pair of RCAs a friend brought around, the Linlai E-845s did at least as good as them in all fields, but they have a greater sense of immediacy, something that makes you feel more connected to the music….

Thanks a lot Rachel, those tubes are real keepers!

Cheers,

Eric”

Positive Feedback review: Linlai™ Global E-300B vs. Psvane ACME300B

Review Juan C. Ayllon spent time with both tubes on his ultra high end Lampizator Big 7 Mk1 Digital to Analog Converter for ‘An Aural Indulgence


  • “If vacuum tubes were wine, the Linlai would be a sophisticated French red Bordeaux blend from the Left Bank of the river Garrone in Bordeaux, France, while the ACME would be a top shelf Cabernet Sauvignon from California’s Napa Valley served in posh steakhouses. 
  • Don’t get me wrong; both the Linlai E-300B and the Psvane ACME 300B render rich, well-balanced presentations, and if I were not making conscious A to B comparisons, it would be easy to miss the differences. And, either vacuum tube will deliver luxuriant listening pleasures worthy of the most discriminating audiophile, enhancing high end tube gear performance and pairing them nicely with highly resolving components like the Pass Labs XP-12 preamplifier or X250.8 amplifier for a spectacular aural finish…”

I got a USPS tracking number…. now what.. why isn’t it moving?

For tube orders from USA customers, we sometimes use Canadian domestic courier service to ship to the border of Alberta/Montana, then customs brokers clear the parcels through US Customs into the USA for final delivery by USPS. Once the parcels entered the USA (AFTER customs clearance and released by US Customs), the USPS tracking number will become live tracking on www.usps.com, and the journey starts from a small town called Sweet Grass, Montana.

Don’t jump when you see your order was shipped from Montana, not from Canada. It’s just cross-border paperwork to get on USPS shipping network.

In the above shipping scenario, USA Customer will receive a 26 digit USPS tracking number as soon as we process your order in Canada – ie. pick n pack your orders and give the boxes to the Canadian couriers (this will usually happen within 48 hours of receiving your orders).

Customers in USA need to wait (patiently) for 2-3 business days for domestic transportation within Canada and border crossing into USA to complete, before starting to click on usps.com for updated USPS tracking.

A New Milestone: NEW web domain with MORE tube options!

For those with sharp eyes, you may have noticed: From Dec 15th 2020, we have migrated our tube site to our new domain:

www.PremiumVacuumTubes.com

What has changed?

First, More tube options to come!

Our previous domain website (www.psvanetube.com) was started a decade ago when we primarily offer Psvane tubes. Now we have added Linlai™ tube brand, and more GF (Grant Fidelity) Special Edition tubes to come. The new domain (PremiumVacuumTubes.com) is a better reflection our upcoming wider range of tube offering.

Plus, in the past we have often received emails from consumers (from various parts of the world) writing about their complaints on their vendors runaway from tube warranty. Either those consumers wrongly took our website as their last resort saver to reclaim their loss from sub-quality tubes, or they simply didn’t read the ‘about us’ section of the website. We feel the new domain will help us to avoid such awkward situation – after all, we cannot provide warranty to other vendor’s tubes sales, but we do take very good care of our own customers.

What is not changing?

The new domain website (www.PremiumVacuumTubes.com) is an exact migration of our previous domain website, with all functions, information and order history remain EXACTLY the same. Customers accounts etc all remain exactly the same and all data are secured hosted in North America with a top quality hosting service provider in USA. Our website visitors, users and customers do not need to concern about their interaction with our business be affected by this ‘behind the scene’ website domain changes.

If you have come to this website from a forum discussion thread link about Psvane tube, Linlai tube, or Grant Fidelity special edition tube, or a Google organic search result, our previous domain (www.PsvaneTube.com) automatically re-directs you to this new domain seamlessly. This post here is to re-confirm and reassure to you that you are at the RIGHT web link destination for the information you are searching for, just with a new name! Our website URL has NOT been hijacked 🙂

 

We will be adding on more tube offerings in the coming weeks and months, from affordable entry level replacement for ‘tube newbie’, value performance driven upgrade for ‘smart shoppers’, and to ultra fidelity ‘best of best’ tubes for the ‘ultimate fi’ lovers!

Thank you for visiting our website. We look forward to doing some tube business with you in the near future!

Psvane or Linlai™? … Make an informed choice

We have received so many inquires lately from customers asking us to help them to make a choice between the two tube brands out of China. So here is a summary of our take – OBJECTIVELY:

  1. Power of design:

High end product design need vision and dedication. Psvane had a track record of pumping out a few series of high end tubes for the worldwide audiophile upgrade market, since they initially launched ‘Treasure black bottle’ tube series back in 2008 till the recent ACME series.

That original Psvane design team includes the same people who left later on from Psvane to form Linlai brand. So, Psvane had proven track record. Linlai™ split out with a good number of the design / production team so they started off with good design strength too. 

Conclusion: We have absolute confidence in the late new comer Linlai™’s design ability to pump out GREAT hifi tubes. Two brands provide varieties to the market – users can choose based on their preference. 

2. Business focus:

When a business grows, they do tend to increase their offering to cover more market segments to increase revenue. Psvane indeed have taken the golden opportunity to expand and fill in the void left by Shuguang tube factory’s shutdown in 2019 due to sale of land and relocation, and Psvane has set the stage for expanding into the mass production guitar amp market, which mostly use small signal tubes and EL34/KT88/KT66 etc. Large triode tubes such as 300B/845 tubes are mostly used by HiFi market and are not the focus of the guitar amp musician market.

Shuguang now has resumed production in 2023. Psvane’s market share is being squeezed so they appear take more aggressive moves to maintain market share. However, we think the whole problem of Chinese tubes is about consistent quality. When Psvane grows to cover as wide scale as Shuguang used to be, the quality consistency might suffer. 

On the contrary, Linlai™ set itself to be a niche player focusing on HiFi market only. They do not appear to take overly aggressive moves for market share. Instead, Linlai appears to be genuinely concerns about quality. Sub-par quality or un-confirmed quality tubes are not offered for sale on their official export website [www.linlaiglobal.com] to maintain brand reputation. 

Conclusion: current Psvane tubes such as ACME series are confirmed by worldwide customers as ‘great tubes’ but quality consistency must be observed by diligent buyers . We are confident that Linlai™ will and may have caught up in the competition with their strong focus in the HiFi market. 

3. Statistics says about Quality Control:

We have randomly taken 28 tubes from each brand that we have received and plotted their plate current. Blue line is Psvane, Orange line is Linlai™. We see a less deviation from Linlai™ measurements than from Psvane.

What does this chart tell us? It says: We are indeed getting great quality Linlai™ tubes with a very consistent measurements! The Linlai™ people are really serious about their products and take our quality control parameters to action and test numbers tell it! In our opinion, those Psvane tubes with plate current less than 48 should NEVER has been released to outside of China market if they were to maintain their brand reputation in the international market. 

4. What if? – The Warranty question:

Both Psvane and Linlai offer a better warranty term than the state owned Shuguang brand used to offer. They are changing the reputation of ‘Made-in-China’ tubes.

Linlai factory backs up their [Linlai™ Global] tubes sold through their own website and their authorized overseas resellers. Buyers tempted by cheaper price and bought the Chinese version of Linlai tubes (it doesn’t have the [Linlai™ Global]) is only covered by their sellers (mostly located in Greater China). 

Conclusion: Buying [Linlai™ Global] tubes does not leave the buyer to hold the bags, when problems arise. Consistent quality means less warranty cases – it will be a better user experience. 

5. How do they compare, sonically?

We know this is the holy-grail question for audiophiles. But since this comparison is all about being ‘objectively’. We as vendor must leave this question to be answered by the audiophile community.

Objectively, we can shine some lights on Linlai™ design which will add to definite positives to the sonic performance. E-series with molybdenum material produce a much stronger electron emission than other type of plate material such as graphite or hybrid plate, and sustain higher voltage. This translates to more dynamic to the sound, better reliability and longer tube life. DG overhang filament series achieves better vibration control than other filament structures. With all these features, we trust that they are evident to well trained audiophile ears to hear the sonic improvements.

Conclusion: we have been selecting high quality tubes from China for over a decade. Our past combined experience does tell us that Linlai™ is a brand with great potential for both sonic quality and reliability – so far we have not seen a single defective tube from our 4 Linlai™ shipments, except one tube broken in handling from China to us.

We hope by sharing the above information and data, worldwide music lovers and audiophiles can be confident in making a well informed choice between the two brands. 

Keep in mind: enjoying music is a journey. It’s not a quest for the absolute best. If there were ‘absolute best’ in the audiophile world, we wouldn’t have had today’s numerous HiFi brands and mind boggling choices from worldwide brilliant HiFi creators. We simply cannot answer your questions about ‘what is the best tube to buy’. 

Happy Listening.

LINLAI™ 845-DG: “Turned my system into the best I have ever experienced…”

Feedback received from our long time customer Barry H. in Vancouver, Canada:

“I now own Space-Tech Laboratory SE-845-100W mono blocks that are single ended DHT pure class A triode OTL power amplifiers that were designed and hand built in Vancouver.  They came with Psvane 845 Hi-Fi tubes and I was very happy with the sonics. Unfortunately, the adhesive holding the base to the glass failed after a year so I went looking for replacements and found Grant Fidelity’s website where I bought a set of Psvane WE845 tubes.  They are great tubes but I couldn’t find the correct configuration of preamp tubes to make music the way I liked.  I then ordered a pair of Psvane 845-TII Black Special Edition tubes that provided the warm texture that I enjoy.

Over the last year, I have upgraded my digital front with a KT-150 based upsampling DAC, re-clocker, switch and linear power supplies to the point where I was suspecting that the Black Special 845 tubes were holding back my system’s potential.  I went back to Grant Fidelity and found the new tube manufacturer, Linlai.  My logic was that if a group of Engineers left Shuguang to form Psvane, who are now a premium manufacturer, then the group who left Psvane to form Linlai must believe they can produce products at or better than Psvane.  Rachel’s honesty about their warranty was all I needed to order the factory grade version of the Linlai 845-DG.

After the 845-DG arrived I listened to them for 2 hours and then began the burn-in process for 7 days, listening each evening for about an hour.  They did improve until the 150-hour mark to the point that I did not hear an improvement at 175 hours.  My impressions of the 845-DG vs the Psvane 845-TII (Black Special Edition) after 175 hours are:

I call them(Linlai 845-DG) 300B tubes that were fed performance enhancing drugs!  Smooth, delicate, air, no harshness and wonderful dynamics. A blacker background with a wider and deeper soundstage with clarity of all instruments.  I can discern a cedar top guitar from a maple one. Cymbals and bells float with a long decay. Bass has the articulation and warmth that I crave so, in comparison, the Psvane 845 T-II sounds like they are wrapped in a Kashmir sweater that must be smearing some details. The vibration of strings on upright bass and piano are easily heard. My addiction to snare drum rim shots is satisfied.

These 845-DG tubes have turned my system into the best I have ever experienced in my home and I couldn’t be happier. They and can lay claim to being expertly designed and built!

Barry H., Vancouver”

6SN7SE: “stunning life -live -like music. HUGE soundstage”

Feedback received via email from customer Lincoln W.:

“Hi Rachel, I thought I’d give you a preliminary feedback on the Treasure Globe 6SN7-SE.  they are simply amazing. A pair makes the entire system sound like a brand new system! stunning life -live -like music. HUGE soundstage. I’m running a DAC that already made the soundstage big, but the tubes gave it more depth, the soundstage became bigger.  lots of air, lots of presence…the music produced was jaw dropping – arms up in the air moments. and there were many!”

(note: Lincoln uses 6SN7SE in a Supratek preamplifier)
