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 like the 6ca7 RCA/Sylvania EL34 Fat Boy tubes in my VTL ST 85 amp. I also like the NOS Mullard/Holland El34 but big money for these, luckly i have 5 of these that test new, also 3 quads of the Fatboy tubes, all test new.........Never know when i'll need a spare.
I have used the New Sensor Svetlana EL34, Tung Sol EL34B, Siemans EL34, and the Gold Lion KT77s. Comparing these to the SED EL34s (original pre New Sensor Svetlanas) I chose to return to the SED. The best of the others were the GL K77. The KT77 had better bass extension and drive, but lost the three dimensional soundstage that I enjoyed with the SED tubes. I found them to have a wide and flat soundstage in my system at that time. The Siemans were inherited and I have no idea how many hours they had on them, though they tested OK on my Hickock Cardmatic.
Consider the Gold Lion KT-66 tube. I used the EL34 for years and switched and OMG! huge soundstage! Analogtubes.com for $168./quad matched set...
I should have said that I have also bought from Jim McShane and was very happy. What are your input tubes if you are going to roll them as well?
BTW the suggestions regarding the NOS power tubes are unrealistic. The prices are as a rule beyond the reach of most mortals.
