I bought a couple of the Shuguang Treasure
Cv181-z tubes for my Modwright LS-100 and one went microphonic in about 3 weeks. I was able to get a refund and put the stock tubes back in.
Shuguang Black Treasure CV181-Z
I feel compelled to post here, having just replaced a stock Electro-Harmonix 6SN7 with a Shuguang Treasure CV181-Z this morning in my Blue Circle DAR integrated.
Good lord.
Probably the best $120 I have spent on my system. Massively improved sound staging, instrument separation, timbral accuracy...even power in the low end.
I'm actually kind of giddy sitting here listening. I knew things would get better, but this has been a revelation. YMMV, of course, but boy howdy...
