Feedback from customer Albert W. via email:
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”
Feedback received from Thomas L. via email on WE274B replica:
I just received my order of the WE274B last night. I have to say I’m not sure what to expect, but hoping that the sound of my system doesn’t take a bad turn. The rectifier tubes that I had been using are Ken-Rad 5U4G and Amperex GZ34. The 5U4G has a thicker sound where as the GZ34 seems to a little harder sound, better bass but less musical.
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 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
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.
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:)”
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.
A feed back from (Thomas S.) a Norwegian with 55 years in the high fidelity hobby with almost no cost and effort spared in search to enjoy recorded music:
“Hi Rachel, Grant Fidelity.
I just wanted to give you a feedback on the tubes you just sold me.
I used to have Cary 211 AD, with their 211 and 845 tube possibilities for amplifying. But, after serious trouble with one of the tubes, that caused me a dangerous repair ( done by myself – guided by Cary on the phone) – I gave them up. I thought of the tube future
expenses and problems of a similar kind.
The last 10 years I have had the scaled down Cary 805 AD with the Cary SLP – 05 preamp. In the meanwhile I scaled up with Golden Dragon Premiere tubes all the way – as I thought they were good enough for me. This matched with Cary SACD player. Focal Speakers. Mundorf AMTs - from 5000 Hz and up. Backed up with Lyngdorf Millennium digital amp
and ProAc satellites behind the main speakers.
Feedback received from Nick B. in UK about Treasure 6SL7-Z:
I just thought I would drop you a note having put the 6SL7-Z tubes into my monobloc amps.
The only word I can think of to use is WOW!
I have never heard bass like that from ANY amp, never mind a valve amp. What a difference it has made to the music.”
