I am really enjoying the Create Synergy 6SN7. So far my favorite has been the Ken-Rad 6f8g for it's amazing midrange. It's weakness is a soft bass. The Create does not have the magic in the midrange but it is good. Very clean and very quiet. Dynamics are excellent and bass is great. I need more time with this tube but it is a keeper and will probably be #2 or #1 in my estimation.
