Tube rolling for Jolida 502B

I have a new Jolida 502 B amp, my first try at tubes. I'm impressed so far, does nayone have experience upgrading the stock 6550 power tubes? Suggestions and or comments appreciated. I'm driving a pair of Meadowlark Osprey's and listen mainly to blues and classic rock.

That's interesting, I hadn't yet considered that. I was driving Kestrel 2's myself(for sale on 'Gon) but was offered a good buy on a great pair of Osprey's.
Thanks,

I should mention current tubes are: Electro Harmonix 6550 EH, Electro Harmonix 12AT7EH and Jolida 12AX7A.

Thanks, lively and engaging is my preference. I listen to a lot of blues and like the vocals right in front of me.

Are KT 88's and 6550 interchangeable? I'm new to the tube scene. I ordered Electro Harmonix tubes to replace the Jolida labeled tubes in the pre amp which I'm sure are chinese in origin. That would give me all Electro Harmonix tubes at this point. Any suggestions?
Thanks ,

Thanks Larry. I saw at the tube store where the current electro harmonix power tubes are highly recommended. Maybe they aren't so bad after all.
