40 watt amp with 8 ohm speakers

Hi, I'm new to this and trying to put together a decent system with used components. Bought the NAD av711 which is a 40 watt amp, and some old 8 ohm Ohm speakers (Ohm Pro 32). Is this a bad match--do I need a more powerful amp for these speakers? Also looking for a cd player to go well with these, for under $500, and would love some advice. Thanks!
