Speaker selection help requested.

looking for suggestions for a match with 50 wpc tube integrated(pacific creek 901 separo). currently using a 4.5" fostex small horn loaded bookshelf. love the detail of these guys, but limited dynamic range leaves me wanting more. i love the single driver sound, but it's limitations are well known. considering the new cardersound smaller speaker being promoted here, but no chance to hear it. also has the smaller driver. am considering the omega line with the hemp driver, the druids are a little more than i want to spend for a second system. In the tampa area, ther is little in the way of opportunity to audition single drivers from anyone.

Any help will be appreciated.
