Compare Shuguang vs ElectroHarmonics 6SN7


Can anyone fill me in on the sonic differences between these two current production 6SN7s? I consider the EH to be somewhat analytical sounding - is the Shuguang any warmer?

the EH is a very smooth non-detailed sound...don't know about the Shuguang....NOS Sylvania, Tung-Sol and RCA are the place to be.

No experience with either of those but I have some re-issue Tung Sols 6SN7's that are surprisingly good compared to the NOS Tung-Sols and Sylvanias I also have.
Glad finally to hear someone speak well of reissue Tung Sol 6SN7. Did you ever compare them to EH made in the same factory? IMO EH sound very good.
