I have a set up similar to yours with a modified Fisher 400 receiver and Rogers LS3/5A speakers that I use to listen to Jazz, Country & light rock music. The system sounds great and has plenty of power provided you don't listen @ ear splitting levels. I generally listen to music at a moderate levels, enough to get the full sound stage out of the system but not so loud that it hurts my ears. I have never heard the VTL Tiny Triodes or the TL 2.5 preamp but have read nothing but good things about them. If you went to a EL 34 based amp you would need have 2 pairs per side since a pair of EL 34s only puts out about 40 watts depending on the amp, which is about what you have now.
I have a VAC PA 90 mono blocks with 4 EL34's per mono block, which I think would be over kill for your speakers unless you like to crank them up to 100 db range.
I think you would be better off talking with a couple of knowledgable tube dealers and let them make some recommendations on tubes. Andy @ Vintage Tube Services and Jim McShane @ mcshane design are two excellent tube dealers that I would recommend. By the way NOS EL34 tubes are about twice as expensive as NOS EL84 tubes. I am sure you can get a lot more out of your system with better tubes.
Good Luck,
