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...

‘I have the CV181 TII’s as well but the globes are a little bit more refined. 

I have had previously used numerous NOS tubes, Winged C’s, Mullard, Jan, Raytheon, Svetlana,etc, and I prefer the Psvanes over everything else by a long shot.

A broader deeper sound stage with a wider sweet spot is my favorite attribute with this tube combo, but a taught punchy low end and the sublime delicate highs are also worththe price of admission. I’ve stopped tube rolling I’m done. I was going to upgrade my mono blocks but I prefer the sound of mine to systems worth far more expensive components. They are not cheap but worth the investment.

I have had 1 CV 181 get really microphonic after about 800 hrs? But that’s the only problem I have had. Great customer service and fast shipping are a bonus. 

I have lots of low hours NOS tubes for sake
