EL34 upgrade

I'm currently experimenting with my Jolida JD302B and various tubes. I have 3 makes and each are vastly different from each. In terms of preference I would order them as such: (1) Svetlana, (2) Sovtek, (3) Shuguang. They are all the budget versions. I am considering upgrading to either the SED Winged C or Gold Lion Reissue. So my question, is whether I would expect improvements to the preferred Svetlana? I have a pricepoint of $200 for a matched quad and not sure whether I need to go higher to really hear a difference. Also I'm sure I'm sure there are others, so please weigh them in as well.

I liked the GL KT77 the best of the small number of tubes I tried in my Jolida...JJ 34, EH6CA7, Svetlana 34(stock tube).

However you need to specify high biasing tubes with the GL 77's...the first set I received didn't come up to bias @ maximum travel of the trimpots.
And I would also suggest slightly under-biasing them.

I hear good things about the GL 66's, but have yet to try them.
