Rega Brio Sufficient?

Howdy,
Before I get jumped on, yes I have found and read an old thread asking a very similar question to my own. I'm still a little worried, though:

I'm new to the whole hi-fi game. I picked up a used Rega Brio (the original one) for pretty cheap a while back and it has suited me wonderfully. Now I'm planning to upgrade my cheap, old Pioneer speakers to Monitor RS6s. I'm worried that the Brio won't be able to drive the speakers well enough, as I think it's only rated as 30W per channel.

I don't do a lot of loud listening, will I just have volume limitations with the Rega, or will it actually lack the oomph to drive the speakers appropriately and have an effect on the quality of the sound?

Thanks.
