How important is Amplifier Continuous Power matching with Speakers nowadays?

Hi Guys,

I am looking at upgrading to a high end amplifier to get some better sound quality along with a new DAC etc. I currently own the JBL L830's which have been amazing speakers. I will look at an upgrade there too. However my concern with getting a high end amp, for example if you take the NAD Masters series, M22 or M32 or even the upcoming M33. These all have continuous power ratings of between 150W, 200W and 300W. 

My concern is if I go for a high end amp that is over 150W will this be a bad match up with my current JBL L830's, at least until I upgrade to some new speakers with a higher continuous power rating?

Or would a better approach be to get new speakers first with a higher continuous power rating (assuming I go down the NAD Masters series path for the amplifier in this scenario)

Any feedback appreciated. Many thanks!
