I posted earlier about the Gallo's and I actually went from them to Dali Helicon 800's, and though I barely had time to get used to the Gallo's, I think I can speak for both.
The Dali's are incredible speakers, but are more sensitve to the upstream equipment, and thrive on transparent components. They are another great option but you will likely be happier with the Gallo's if you do not plan on upgrading electronics, just my opinion.
The Gallo's don't seem to need as much power, and are less revealing in the highs making it less fussy about the components, especially CD players. They throw a huge soundstage and have excellent bass extension for such a small speaker.
FYI I am using Bel Canto components through the whole chain and running a bridged Evo 6 to the Helicons at 380 wpc and they really open up with lots of power.
