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.

Have people experimented with the 6SN7 for the gain, OD3 or 6080? Do these tubes make much difference in the sound quality and is their synergy with the 6SN7 for the left and right channels? Thanks in advance for any responses.
