New Addition! - Nov 20th, 2013: Shuguang Treasure CV181-Z has been added back with same ‘Select’ quality as we did with the KT88-Z as described below. This model is highly popular with ModWright equipment and many high end pre-amplifier, integrated amplifier as driver tube, or in 845/805 type Monoblocks.
Update – Aug 26, 2013: We are adding back in KT88-Z model of Shuguang Treasure black bottle tubes now (Aug 2013) with our newly formed quality control collaboration with Shuguang tube factory.
Grant Fidelity discontinued our offering the Treasure tubes in 2011 as the original ‘Treasure tube’ design team left Shuguang to form their own company ‘Psvane Audio’ and offer tubes under ‘Psvane’ brand. From 2011 to now, Shuguang has restructured its design team but the Treasure tubes have been sold through various channels with no clear quality indication. Grant Fidelity now has formed special collaboration with the Shuguang quality control team to ‘select, screen and supply’ tubes that Grant Fidelity deem to pass our quality requirement to meet customers’ needs for ‘once gone back, never look back’ .

“I pre-ordered my EL34 quadtube PSVANE PH metal base replica from Grant Fidelity. If we were to put my customer experience on a scale from 1 to 10 I would rate it 10. Shipping was fast and included everything that was described on the website. It even came in a big and solid box with a foam so that the tubes would arrive securely. The tubes did not even have a scratch on them and were a great liability. My power amp is a Lectron JH50 and the tubes I had at this time were Mullard’s B coded double Halo XF2 made in England. My ancient tubes were still in great conditions and working perfectly. I switched them with my new El34 PSVANE ph metal base replica. After around 50 to 60 hours of listening, I found out that these tubes were really faster than my ancient ones while keeping the same musical quality that I got from my Mullard’s XF2. The EL34 ph metal base is much more transparent, has more bass punch, seems to have a more dynamyc sound spectrum. Each time a song changes flow, by being quieter or louder, the sound still seems alive and going. PSVANE’S Ph metal base replica EL34 gave me the best sound I had in years, even beating my ancient tube. They are clearly the best EL34 I ever put in my power amp and are probably the best new produced EL34 on the market right now. Personally, they are the best I’ve seen and heard. Read more...

“Hi Rachel. Received the Psvane 12AX7′s yesterday. My intent is to use them as the first stage in the phono section of my Rogue 99 Super Magnum pre amp and based on what I’ve heard so far they are going to perform that function admirably. To break them in and get a feel for their performance/sound quality, I installed them in the V2 and V5 second voltage gain positions of my series IV McIntosh MC275. I have driven them with both a Telefunken ribbed plate 12AX7 and now a REAL Tungsol long Black Plate 12AX7 in V1 the first voltage stage/phase inverter. The Psvanes clearly let me hear the differences in the two tubes. I have had both new production and NOS tubes in these positions. The Psvanes are the equal of the most recent (RCA black plate 5751′s and prior to that Real TungSol Long Gray plate 12AX7′s) and easily outperform all other current production and some late 50′s RCA long gray plate 12AX7′s. And….that’s only with 16 hours on them. “

Some users have reported that they experienced Psvane KT88-TII series reliability issue in the past 3 months including tubes shorted unexpectedly within short period of usage.
Although all tubes from Grant Fidelity were tested multiple times before shipping, the reliability issue was caused by a minor structure problem that can only be identified when a tube is heated over extended period of time. To correct this issue and continue offering Grant Fidelity customers the highest possible quality tubes, we have returned all our stock acquired prior to April 15th back to factory for a new batch that has the issue addressed in production.
New stock of Psvane KT88-TII series GF Grade A tubes now are in stock and we will start shipping back orders and warranty replacement from our Hong Kong warehouse right away.
Thank you for all customers support to our continuous efforts in pursuing high quality products.
New models have been added to the Psvane HiFi Series to offer worldwide audiophiles more varieties to experience 300B and 101D sound.

Feedback received via email from customer Chris in Australia:
“Hi there, Rachel, just wanted to let you know that the tubes arrived in top condition on Friday 8th. I popped the 12AX7-T in first for a few hours and although it needed at least a couple of hours to get over the light bass and slight tonal greyness, the transparency of these Psvane tubes is wonderful! After 9-10 hours it simply becomes an essential addition to the TRI amp! There’s no going back after that.
To keep it simple, Rachel, I gingerly replaced the stock output tubes with the KT88-Ts and all went well and two days later everything seems fine, don’t know what happened all those weeks ago. Read more...
