What speakers would match well to my tube system?

I'm looking to get the right speakers for my new tube system. I purchased a Space-tech VP-105 amp, 4/8 ohm selectable, and power output 100Wrms class AB (optional 50Wrms class A). I have heard that Soliloquy has the 5.3 model and that is a fine speaker for tube amps. What are your thoughts on this? The room size is 25' x 15'.

Any suggestions fitting into the price range of $2,000 - $4,000 would be great, and thank you.
