Dude's 6SN7 replacements with Chinese CV-181/6SN7


After about 3 months of breaking in the Dude, I think it's time to do some 6SN7 tubes rolling. I know this topic has been discussed before but I missed the thread.

Instead of the NOS 6SN7 tubes, I am thinking of trying the Shuguang CV-181Z or the Sophia 6SN7. Both are very similar prices at about $200/pair.

Have anybody tried any of them before with your Dude preamp?

Any opinions or suggestions are welcome.

I have a tube DAC that uses a single 6sn7 as output. I compared the shuguang black treasure and Sophia tubes in a direct comparison. The sophi has a slightly better dynamics overall, slightly better soundstaging/imaging, noticeably better bass slam and extension. However, its midrange is not fleshed out and natural like the black treasure. It is most apparent on female vocals. IMO, the latter is more enjoyable and less fatiguing in the long run.
