‘amazing… better than reissue WE300B’
- from Robin Waytt, owner of Robyatt Audio (www.robyattaudio.com)
“The new Shuguang Treasure Series 300B-Z tubes arrived yesterday. These Black bottle carbon coated tubes are kind of unique in appearance, and construction, so I thought I would try them!
‘fabulous’ – from customer in Russia

‘I discover a great (maybe the greatest) 300B tube’
- from customer Lucian R. in California:
“I just wanted to let you know that yesterday I exchanged all the tubes in my amplifier for ones I received from you.
I am impressed with the sound and if the tubes sound like this immediately from the box I can imagine how they will sound after a couple hundred of hours….
JJ 300B vs. Treasure 300B-Z

TJ Full Music 300B mesh plate vs. Treasure 300B-Z
from customer Doron O by email:
“Hello, Tubes arrived and are playing along. I do not think they are going back to you anytime soon…:-) Very good from the get go. Compared to the existing TJ 300B/n Mesh Plates the SG 300B-z have massive bass, they sound smoother, more relaxed, mid range is fuller (more lush) yet clean – more meat on the bones so to speak. Very seductive and un-fatiguing tubes, exactly like the experience Ian presented in the forum.”
‘better than TJ 300B carbon plate and Sophia 300B carbon plate’
From customer Jimmy P. by email:
“I received the tubes last Friday, i’m very impressed with the sound right out of box! Without burn in, it was already better than TJ Full Music 300B Carbon Plate and Sophia Electric 300B Carbon plate.”
‘sonically as good as KR300B’
Grant Fidelity provided a pair of sample Premium Grade A 300B-Z to TNT-Audio.com. Reviewer Geoff Husband says:
