Wright WPA 3.5's What's Next?

Thanks for the responses gang!Someone emailed me privately and suggested i may want to swap out the stock Sovtek 2A3 to get more of what i am looking for.Does anybody have any recommendations for a sweet, warmer and still punchy 2A3 tube?
Also,even though the minimax preamp is nice could i do better by upgrading in this department perhaps?Just actually got it not long ago and am definitely enjoying it.So perhaps things can even get better by a further upgrade here.Any suggestions for even better preamps that won't dig a hole in the savings to deeply?

Thanks for the help Darkmoebius.Ya know these speakers are also used as studio monitors and are really revealing.They can sound incredible with my system and it seems to have alot to do with the actual recording(cd)i am listening to.Maybe there are just alot of bad recordings because sometimes i play some discs and i am amazed how good things sound.Maybe it is the bad recordings that keep me wanting better equipment ; 0?

Do 45's have the punch that this Wright 2A3 have?I see Danner that you listen to classical music exclusively where i am all over the place with my listening habits.

thanks everyone!!

Thanks for the help people!!Perhaps when i get some more coin together i will spring for those Sophia Electric Princess's.Does anybody have any experience between their standard Princess and their premium Princess 300B?There is definitely over $100 difference for the premium.I think it is near the $450 a pair range.Getting pretty pricey for me for those tubes but apparantly people seem to think they are worth it.How much life do you get out of tubes like these?
Thanks for the links.Very interesting and news to me and perhaps a direction to look towards.Also was recommended the EH 2A3 but also understand it is not in the same league as the Sophia but also alot less money.Any thoughts on the EH2A3 compared to the Sovtek from anybody.I know Stew has had some comparisons but was wondering if anyone else compared them as well?
Thanks!!

Update!!
Well i finally have gotten the means to purchase the Sophia Princess 300B 2.5 tubes for the Wright 3.5's.I only have about 5 hours on them so far and i have to thank you guys who recommended this tube to me.If this tube continues to get better up to 300 hours of break in then i am in for one joyful ride i do believe.The amount of lushness i was looking for is here now.Very nice!The sound is nice and inviting top to bottom.Everyting has been improved thus far or as for what i was looking for i should add.Great tube so far and thanks again for the recommendation!!Yeah i am sitting back at my computer which is way out of the sweet spot and i am constantly looking around and listening with a smile on my face now.VERY NICE!! : )
Still looking for advice from you guys or help with my system to take it even further from here.Just how far can this thing go without getting crazy with the cash is the question i am asking myself now after just this fine tube replacement?
HAPPY NEW YEAR GANG!!!
