EAR534 wouldn't be enough to drive those 87db speakers.
There's a pair of VTL MB-125s listed here for $4K, that would be a much better fit. Manley and Rogue both also have many models >100w that would pair better with your speakers.
Output tubes each have their own characteristics. If you can't listen to a number of amps of varying design, at a minimum try reading up on comparisons of EL34s, 6650s, KT150s, etc.
Cheers,
Spencer
