I absolutely loved my PSVane WE Replica 845s in my Sophia Electric 206 powers 845 monoblocks. They took the system to another level, particularly in the midrange, over the stock Shuguang 845 B (or A? I can't remember). I've since sold the Sophias and the WE 845s and switched to an OTL amp. The journey never ends.
I did thoroughly enjoy my time with the 845s, though, and my audiophile friends (and my wife of course) all thought I was crazy to change anything as that was the best my system had sounded to that point. The OTL sound is pretty special too, though, if you have the right speakers for them.
I highly recommend the WE 845 replica tubes and hope you enjoy them as much as I did.
