FrankHarveyHiFi:I'd look at the PMC DB1i's, which are quite a lively performer with plenty of detail. Although I'd also look at Neat's offerings, which are also similar, and would recommend the Motive 2se's in particular - a little more, but well worth it. KEF's new Q series are also worth a look - this is an extremely strong range of speakers which are great all rounders, and again, relatively easy to drive. The imposing Q900's are going to be giving higher priced speakers a good run for their money.
Agree 100%. The PMCs sound fantastic at the end of Naims, much larger and with plenty of bass than their small size suggests. And Neat speakers are said to work very well with Naim, (as are Harbeths).
Yet another brand to try is ProAc - maybe something from the Studio range would fit your budget.
