I have NOT heard these speakers, so I cannot comment on their sound. However, this reviewer took the time to write a lengthy and detailed review of the Polk Audio R-30 Reference Loudspeaker Monitor. It would SEEM to be a strong consideration for your amplifier power and budget considerations. The reviewer states:
Just an idea, and as I said, I have absolutely NO personal listening experience with this speaker--NO firsthand knowledge. So beware. But this review caught my eye in the bang for the buck category.
"With an MSRP of $400 per pair it must be considered a most worthy performer but at its actual street selling price of $78 to $200 per pair...you just ain't gonna find anything as good looking or sounding!"
And he also says:
"Power Handling is such that the R-30's are recommended for use with amplifiers rated at 20 - 100 watts per channel @ 8 ohms. Efficiency is rated at 89db @1w 1m."
