Thank you for the replies on this! I think I am actually moving from the VAC Renaissance amps to the newest version of the Phison amplifier. It is the first amp that I have put in my system in place of the VAC that has left me happy. That being said I liked the Shuguang Black treasures in my Renaissance amps, in case anyone falls on this thread.
When my WE tubes started to fade, I went to a PSVane pair. The boxes were all in Chinese, so I don't know the model. They have grayish plates and clear glass, but aren't the replica tubes. In fact, I can't find them after searching on the Web. (They were supplied by Audio Note (UK)). They have more distinct bass than the WE300B, but they can't match the rest of the WE300B.
