Bell Canto C5i Integrated Amp with B&W Nautilus 803 Speakers. A Question

The B&W speakers are rated at 90db....8 OHMs .

The manual states Power requirement is 50-250 watts.

My question is :

The Bell Canto is 60 watts at 8 OHM's. High voltage

When doing my research, I have been told that more power is needed

for the B & W 's.

 Opinions ...will this amp be sufficient for the B&W 's?

Thank you
