Feedback received from customer Vismantas B via email:

“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:)”

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.

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.”

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

Best regards

Denis”

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!

A new addition to the highly popular Shuguang Treasure series! We have brought in a very limited quantity to test market – if you are adventurous and experienced in tube rolling, we welcome you to take advantage of our introductory pricing and let us know how they compare to other 845′s on the market.  Order yours HERE.

Like the rest of the ‘Black Bottle’ original Treasure Series that was introduced back in 2008, this model is the first venture to introduce carbon coating to high voltage 845 tubes as a technical break-through.

Feature:

- Carbon compound coating to quickly dissipate heat generated from tube operation to achieve a ‘self cooling’ effect, plus absorbing external interference

- High quality German cathode material and 10% more enlarged emission area than typical 845 tube to ensure sufficient emission at time of high dynamic signal playback

- High voltage resistance design to ensure no flashing short will occur in operation

- Pure 24k gold coated grid to reduce internal noise and reduce secondary grid emission

- Elegant design tube base and leave no finger print residual

- Gold coated tube pins to improve conductivity, reduce signal loss and improve output efficiency

- Suggested burn-in time: minimum 100 hours, recommended 200hr for full break-in

Instead of typical tech talk about a new tube launch, this time we have a story to tell about the type 50 replica tube’s birth… by Steve Berger, a long time audiophile and music lover resides in NY:

If you cannot wait to finish the whole story and wish to order right away, get to order page here.  

“Foreword by Steve Berger:

In the early 1990s I got a call from Vincent Gallo. He had seen an ad for a Gibson GA-50 guitar amplifier that I was selling.

When I walked into his apartment, performing delivery of the goods, Chet Baker’s “Happy Little Sunbeam” was playing on a system consisting of a Western Electric 91A 300B amplifier and a lone Western 757 speaker mounted on the wall.

I had never experienced such sound before: Chet’s trumpet was right there in the room!

This was my first introduction to directly heated triodes and my life would never be quite the same after that day.

Chasing the sound I had heard at Vinny’s, I walked into the now legendary “Fi” audio store located at 30 Watt Street in New York City – what an address! Walking through the door I looked behind the counter only to see the father of my boyhood best friend – Pere – Don Garber. “Stephen, is that you?” Don said and once I acquiesced and he kindly let me peek into the secret vault of New York’s most extreme underground audio society. There, I heard Noriasu Komuro’s three stage, direct-coupled 300B amplifiers, J.C. Morrison’s three stage, split RIAA phono preamplifier, playing through J.C.’s Focal-based speaker system. I was floored. Never had I heard such truth, honesty and such coherent clarity. “Waltz for Debbie”. I was at the Village Vanguard!

I was hooked but the price of Don’s wonderful amps was out of reach, even for the committed and hard working jazz guitar player I was. However, being a plucky kid from Brooklyn had me develop the thought that I could learn how to build such a machine. J.C. walked in, ever most charming and kind, and asked, “can you read a schematic?” to which I replied with utmost confidence:“Sure!” (not that I really could actually). I left the premises with two chassis, a complete set of power transformers and output transformers and the rest is history.

I built my first amp from J.C.’s schematic. It was glorious! Life, continued study, hard work, and luck, brought me to Tadataka Uchida and my first “50” amplifier.

Uchida was a magician, an accomplished cook, an audio aesthete of the most supreme sophistication. He also happened to be the importer of some of the finest and most esoteric Japanese audio components including Tango, Tamura and Denon cartridges, all at a time that many would qualify as America’s darkest of audio ages.

He welcomed me into his home and into his life. We became very close friends, ending many evenings at his place enjoying his wonderful food and listening to his RCA phono stage into a two stage WE 205D amplifier playing into vintage Altec Valencia’s.

One evening in 1995 , Uchida gave me a pair of un-marked Globe “50s” and said, “Build an amp with these”. I just about cried. It was like he had given me the key to the kingdom.

I immediately went to work on it. I showed Uchida each and every drawing. By this time, Uchida had been diagnosed with very late stage 4 cancer, and we spent many many hours together. I became his caregiver in his last days. He wanted me to build this amp. It was my mission to finish it for HIM and so I did!

“Uchida” Bronze 50 amplifier by Steve Berger – Picture by Dave Slagle

“It looks like a city” he proclaimed and he loved it.As a final step to my “induction”, he gave me the “precious of precious”: a pair of ultra rare, never seen before mesh plate 50s!

Those who saw The Wizard of Ozwill without doubt remember Dorothy walking out from the cabin, when the picture went from black and white to Technicolor! The depth, color, vibrancy was heretofore, unheard.

For the last 21 years, I’ve been playing these magical devices to all in my circle to much applause and adulation, leading to this courageous attempt to revive the best audio tube to ever have been produced.

These ARE better than the originals!

So, after all this time, we now have access to a new production, genuine replica of a pre-1929 mesh plate 50. While we made every possible attempt to accurately replicate the original tubes – making use of many non-working samples, manufacturing processes allow us to produce a tube with better vacuum and better quality materials. We went so far to source some of the critical parts in the US, so as to ensure the highest possible quality and consistency.

We hope to provide many years of the most vibrant audio listening experience.”

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.

Conclusion

After hearing the Shuguang Treasure KT-120 tube I can declare my search for the best KT-88/120 tube is over.  I have no desire to reinstall the Ayon Audio KT-88SX tubes if that tells you something.  I wouldn’t hesitate to recommend these tubes and at the price of $349 a quad they’re a steal. ” Read full review here.

Feedback received from Thomas L. via email on WE274B replica:

“Hi Rachel,

After plugging in the WE274B, without any music playing, my system seems very quiet.  It almost seems my system was not turned on.  When the music starts playing, music just emerged from the sound stage.  The Impression that I keep getting while listen to my system with this tube in my DAC was much better resolution, smooth, and punchier bass.  (Notice I said resolution, not detail.) Soundstage is more spacious and deeper.  Definitely less listening fatigue than when I had the GZ34 or the 5U4G in the DAC.  I have to say this tube is well worth every penny.”

Feedback from customer Albert W. via email:

“Hi Rachel,

Like the previous review on the psvane tube website I would have to second his opinion of these tubes. My previous tubes were a Shuguang 274B but the difference between those and the WEs are night and day. From the first start up, I’ve noticed that the background was much more black. Without a doubt the definition was superior along with the soundstage. The tubes may be pricey but I believe they are worth the extra cost. Thanks. Best Regards,  Albert”

The long out-of-stock Treasure KT120-Z is now back in stock for immediate shipping from Canada to worldwide!

It has a new ‘cobalt blue’ glass enclosure now to not only allow you to see the tube glow, but also better dissipate heat when tube is in action. We have done extensive work with factory to improve on tube stability, and apply a very strict selection process, including not only extended factory burn-in time, but also additional round of screening and re-testing in Canada before shipping to customer.

Order yours HERE before it is sold out again!

I had the tested Tung-Sol KT-120. Installed on the Sonic Frontiers for quite a while. I installed these new PSAVANE KT-120 on the same amp hooked up to the top of the line Pathos «  In Control «  pre-amplifier. Speakers were the ProAc Response D20 R ( ribbon tweeter) and later, the new Martin Logan Electro-Motion hybrid electrostatic speakers.

Upon installing & biasing the new tubes on the D20R, I noticed a right away increase in transparency , detail in resolution. It became even more obvious when I upgraded the speaker cables to the new Cardas Cygnus.  Also, an increase in depth very noticeable with either set of cables.

Also with both set of speakers, there was no brightness at all with these new tubes. No forwardness either. Overall, these new KT120-(Z CB)are definitely an upgrade over the Tung-Sol. And so far, they have been very reliable. And they look good too.

Have a good day,

R.

Sometimes we wonder if there is a limit of high end… apparently for tube producer from Asia, there is no limit yet!

This new custom version KT88-Z CB cobalt blue Super Tube seems have “surpassed the current high end KT88 tube offerings, in instrument separation and frequency extension on both ends”, according to factory in-house comparison to competition.

Order yours now to experience the new limit of ‘high end’…. KT88 doesn’t have to be low resolution as some people perceived!

Feedback received from customer on Psvane 12AX7-TII via email:

” I was very happy with the Psvane 12AX7-T compared to the NOS Electrohome 12AX7 which is Canadian 1963 produced tube that closely resembles Amperex Buggle Boy. This NOS tube is quiet like Psvane 12AX7 but the NOS tube is roll off on top and bottom while midrange has that clarity and bite that makes vocals sounds crisp. But prolong listening, it sounds like typical SET amp that accentuate midrange. When switch to Psvane 12AX7-T, it is just as quiet but has fuller body, bass is deeper and punchier, highs are more pristine. This makes orchestra music more complete and musical, satisfying. When I watch movies, I hear more ambiance cue and soundstage is larger. ” – Jimmy P.

Feedback received via email:

“Hi Rachel,

I received the 12AX7LS super tubes and their performance is super!

Put the new tubes in and turn on, first 10 mins, comparing to Psvane 12AX7-TII…the new super tube has lower noise floor, sound is more dense and transparent, bass is deeper and better bass layering. Sound is richer and much more transparent.

I’m playing internet FM radio and it is finally making music now. Before that, I can hear it is digital and an inferior sound, but not anymore. I’m less critical of my internet FM radio through streamer and enjoying it. Vocals is more lifelike. No regrets buying this super tubes, high value and performance for the price paid. After playing 45mins, details are more resolved and soundstage is deeper. Seems to have better air around instruments. Overall, amazing, musical, without sounding louder. – J Pang”
