Which 211 tubes for my Wyetech Topaz

How about the Elroy tube. Also are the r a that much better than the GE tubes. Thks

Oops meant Elrog tubes

I've used the GE and Shuguang tubes in my Topaz.

Shuguang are good value for the money the GEs are richer sounding to me. I have not had the opportunity to listen to RCAs as I have never found a good pair at a decent price.

Elrog's sound interesting but too many comments on reliability....who makes them available in North America?

Thanks
