Choose your speakers first, and then buy an appropriate amp, rather than trying to match speakers to the Bel Canto integrated amp. Since you mentioned "something like the Bel Canto S300iu", I'm assuming you haven't yet purchased an amplifier.
High sensitivity (90+ dB)/8 ohm nominal impedance/flat impedance curve (low impedance not dipping below 6 ohms) speakers will provide you the greatest latitude when selecting your amplifier.
Can you do better than the Druids in a high sensitivity, high impedance, full range loudspeaker for $2500 used? I'm not sure...maybe a Proac model? Lots of people loved the Druids for a long time until a newer, fresher rabbit showed up in the field. Buy them used for around $1500, and you'll be in good shape to try them and resell them with little loss if you don't care for them.
Having said all that, if you already own the Bel Canto S300iu, then as Shadorne said, you have a large selection of speakers from which to choose that will perform well with the amplifier. Near the top of my list would be used Vandersteen 3A Reference.
