The el84 and el34 are my two favorite sounding tubes.
What you really need to look at is how their characteristics are going to integrate with your speakers. The speakers are a much larger piece of the puzzle- feeding them properly is critical.
I would choose the speaker first and then consider how to drive it.
One other thing to note is that I don't think it is neccessary to spend the kind of money you are talking about. If you look at what goes into a push pull tube amp, even one that is point to point hand wired it just cant justify $5k in my opinion. These are simple circuits with relatively few critical parts. $.02
