I have been running a pair of the Shu Guang WE6SN7 Plus tubes in a Dennis Had Inspire headphone/preamp for about a year now and love them. Have about 700 hours on them with no issues at all and they replaced a pair of Sylvania 50s chrome dome tubes that have proven to be my favorites till the Shu Guangs showed up, still go back to the chrome domes every now and then but do prefer the Shu Guangs overall. I am a Shu Guang/Psvane fan and have been since I tried their smaller signal tubes 10 years ago, currently run at least 23 of their tubes in preamps, amps, headphone amps, dacs and phono stages and have had no failures as of yet. VIVA tube is a good source and I have had really good luck buying on ebay direct from China. I thought it would be prudent to look for readily available current issue tubes and the Psvane and Shuguangs have allowed me to have a go to that is fresh stock. When I reference their small tubes I am referring to their Treasure series. I just bought a Psvane Classic Series 274B rectifier Tube and hope it works out as right now Brimar rectifier tubes are my favorites. Enjoy the music
Anyone try modern 6sn7 Shuguang WE type vs NOS RCA,Ken Rad
I just bought a KT-88 amp that uses 6sn7’s and the matching preamp uses the 6sn7 tube also. It came with kt88 Shuguang WE plus and all 6sn7’s in the amp and preamp both came with the same Shuguang WE plus.
I have a huge stash of old 6sn7’s Ken Rads vt231, gray glass rca, Sylvania vt231 and many others. I am going to pull them out this week and see what these new production tubes can do.
I’ve never used new production signal tubes. To be honest the Shuguang sound pretty good but have never compared them to anything.
What are your views on these new tubes are they even close or as good or even better? Are they cheap and will go up in smoke, thanks for any insight.

@lowrider57 sorry, stepped away from the thread for awhile. Just checked the Viva tube website and I do not see where they even have shuguang, just psvane. The measurement given of 2 inch width is spot on @1.98 inches. I purchased mine off ebay from Vicaudio_1 out of China but he does not show them for sale at this time. I have seen them pop up on Audiogon from a dealer out of China and for some reason I want to say it was Pavanedirect, I even tried to order them from him when I bought mine but they were out of stock. I believe Grand Fidelity has severed their ties with Psvane. If you can find a pair and squeeze them into your set up, you will not be disappointed. FWIW, I have tried a few sets of the Psvane and Shuguang 181 (grey glass) treasures in several different applications and didn't like them at all. Enjoy the music |
