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...

Old discussion, but thought i would elicit feedback - I want to replace the stock 6SN7 tubes in my preamp, but I'm unsure if I should go the NOS route or the "new Chinese" tubes? I'm leaning towards the Black Treasure CV-181-Z, but I would appreciate feedback from anyone who has had the BT tubes in a preamp for any extended period of time. At the prices being asked of these (and solid NOS tubes) I don't want to head down the wrong path - very expensive to recover from the wrong decision. My other option would be 1940s Sylvania black base (non-metal base) NOS tubes.

Thoughts . . . . ?
Thanks, mdemaio - I appreciate the feedback - think it's the BT "Z" for me and my Cary Audio SLP-05. Yes, all info I find online points to the BT "Z"s all fitting atop the SLP-05 without modification. I'll revisit this thread and post results once installed and broken-in.

Cheers.
