These are really good tubes....detail that stands with the SED el34's, but with a bit stronger, clearer top end. Supposed to be more low end, too, but I did not notice this so much as the high end, which is very good. I don't miss the SED's any more.....
If they last as long, I will really be impressed! Definitely worth a try, IMHO.
