Do you like these speakers? If not sure then either as J-Bailey says single driver but I don't know which would be quality and about $500.
An alternative are high efficiancy Horn speakers like Klipsch Heresys which you can pick up used for about $400. They are not really a small bookshelf speaker but are rated at 98db/W/M. You will hear a lot of arguements about the coloration of horns versus the "purity " of single drivers.
On the other hand there are plenty of Chinese PP EL 34 amps yielding 35-40 wpc that may be more realistic for you. Many of them go for a song used in good shape.
