Thanks for answer. I followed recommendations by Chris Johnson at partsconnexion and ended up with a similar collection of tubes (see my system link after you click on my name, since for some reason it does not show up otherwise). I really like the detail the EH12AX7 brought to my system and and enjoy the much tighter bass with the Svetlanas. The Mullard 12AT7 I have were really necessary to keep the musical qualities of the Jolida. I have to agree with you. I think the tube rolling was a huge improvement over the stock amp.
I am not sure whether I will add the tube dampers any time soon. I am thinking about first upgrading the powercords (maybe to the vh audio ones as well). How is yor experience with the "different" flavors, i.e. flavor 2 vs flavor 4?
Thanks again,
Rene
