Feedback received from Peter in Germany via email:
“These tubes really needs time (120+hr) to grow. Now, they are absolutely great. The best i’ve ever heard before, period……I’m very happy too with the big sound of the LS-type in my big amp. Even after 72 hours they sounds good, but now, after 120+hours, I’m in heaven. Tonality, detail (!!!) and room are just great. An absolute notably improvement to the Psvane 12AX7. The warm, precise, detailed and big sound fit perfect to my preference.
This new tube-setup let me discover several tones, noises, coherence in my musics I’ve never heard before, incredible!
Feedback from a recent customer Denis who purchased Psvane 12AU7-TII (GF grade A):
“Bonjour at Grant Fidelity
My Psvane 12Au7 are in, and as soon as i put them in my Italian hi fi preamplifier i loved them immediately, i mean not the tube themself but the music coming out of them.
i own NOS Amperex 12AU7 that i found amazing but lacking top end absolute clarity and transparancy, and i also tried the new Northen Electric 12AU7 that a friend borrowed to me , but with them i feel an evident tonal inacurracy in the mid-range, especially in the piano and vocal.
The psvanes beats them a lot!! better musicality and clarity/definition
i am very happy with my purchase

The prototype 12AX7 LX model has been very popular with worldwide interest and those who didn’t get hands on them have asked us to extend the offer longer… so here we are.. We have decided to extend the ‘feedback wanted’ price to our next prototype run with ‘carbon polymer black coating inside the tube’…Gold pin offering will be held off for now due to high gold price on commodity market.
Order now to secure your pair!
Hurry! – limited quantity only for ‘feedback wanted’ run and we love to hear from you how they sound for your ears, or your audience if you are a guitar player!
- ‘High Polymer Compound Carbon’ (HPCC) material used inside the tube to further quiet down the internal tube noise
- 25% more cathode effective area, improved cathode material, which lead to 25% more stronger electron emissions
- Improved triple mica plate structure to greatly decrease tube internal noise, make the tube even more suitable for portable application such as in high end guitar amplifiers and ultra high end home audio system so the tubes are less susceptible to system vibration induced tube noise. If you have a very sensitive super high end preamp and you have been quest for that ultra quiet tube, this might be your final answer. (As a reference, similar triple mica structure NOS 12AX7 tubes are now going for $250 per pair on the market) Read more...
Feedback received via email from Cary Audio’s technical staff about using WE845 in Cary amps:
“ I was able to evaluate at least the aspects I was most concerned about, e.g. the dissipation factor in the 805 amps. The 845 tube in these amps are biased right at the rated maximum for that tube, and I was concerned the Psvane version having only 75 watts of total dissipation might not work well in these units. Since some of our customers had started using them I thought it would be a good idea to see if they in fact would survive. In addition, I wanted to see if there was any improvement in the sound. As it turned out the dissipation set in these amps with the samples sent were at about 115 watts per tube which is considerably above what they are rated for. However, I let them play continuously for over a week and bias remained stable, and there was no red-plating. In addition, the improvement in presentation was considerable. I never noticed the graininess in the Chinese 845 tubes until I tried these. The realism is almost scary with the Psvane tubes. Soundstage more 3-D and centered. Female vocals are like honey. All and all these are a substantial improvement over the stock tubes, and I will begin to recommend them as upgrades. I can’t tell you how much I really appreciate Grant Fidelity lending me these as they really put these amps in a whole new league.”
Here is what reviewer Mark Wheeler said about these globe shaped tubes:
“If your 6SN7′s are on show and there is space for them, there is every reason, sonic and aesthetic, to install the Shuguang Globe 6SN7-SE. In a high resolution system, especially of the low-to-no negative-feedback persuasion, these Shuguang globe 6SN7-SE bottles are the state of the new-wave-of-valve-production (NWOVP). So far Shuguang have not put a foot wrong and we can hope they continue to innovate new versions of those classic valves we all love.” Read the full review here.

“Wow, your 300bz tubes are unreal… Sound is of another world, i use with lm-210ia amplifier .. Definitely i buy one more pair of these tubes:)”
The long waited Treasure KT120-Z tubes are finally in stock! This model is much more difficult than KT88 to make, and production process take much longer. Our first batch has arrived to warehouse and all pre-orders have been processed for shipping.
For those who have been waiting for new stock arrival to place order, this is the time to get yours before it runs out…Thank you for your interest in this Treasure tubes that will replace TungSol KT120 with more musical sound.
It is official! The Treasure KT120-Z has been reviewed by Stereotimes and here is what the reviewer said – “I could live with this tube for a long time.”… “It is a steal!”
The review was done with a high end Ayon integrated tube amp which uses KT88 and KT120 type tubes.
“On various cuts the Shuguang Treasure KT-120 tubes sounded more interconnected across the entire frequency spectrum. The Ayon Audio tubes seemed less controlled and transparent by comparison almost lacking in headroom and while the Shuguang Treasure KT-120 tubes were more illuminated in the midrange and high frequencies displaying a more live sound. I clearly preferred Shuguangs it to the Ayons.
Over the course of this review, some cable and system grounding changes were evaluated and based on the transparency of the Shuguang Treasure KT-120 tube, it was always easy to hear even the subtle differences each system change displayed. You know what I really like about this tube in this application? It’s the reliability. I’ve power cycled my Ayon Audio Triton MKIII many times over the course of this review and have never once had a tube failure but I have almost a dozen tube failures with the stock tube. Read more...
