Speakers for YBA passion 100 Amp

I recently purchased a YBA passion 100 integrated amplifier (5o wpc)to replace a dying old linn majic integrated. I now want to upgrade my speaker (5 to 6K used market), actually a pair of Meadowlark swift, for something with much more presence and definition that will fill a 24'x24' room with cathedral ceiling.

The rest of the system:
Arcam cd73t
Slim device +Benchmark DAC1
MacIntosch XLS112 sub
MIT interconnects

I mostly listen to small jazz ensembles, world music and classic.

I will upgrade the cdp after purchasing the speakers (I know, I know... the source is the most important piece of equipment but I have the feeling that the Swifts are now the most limiting part of my system).

Since the relatively low output of the amp, will I be able to fill that big of a room.
And I am very curious of your sugestions.

Thanks
