Need some Amp help - a little new to properly powering speakers


Hello. 

 I have some polk LSIM707s that I thorough enjoy.

However, at the moment I'm powering them using a Yamaha aventage 3070 receiver which at 150 watts at 8ohms sounds pretty darn good. 

However, since these are rated at 300 watts at 8 Ohms, I assume I will need some more power. I notice at lower volumes a lot of the imaging and clarity disappears. 

I am looking at buying a 300 watt emotiva Amplifier, or a 500 watt emotiva amplifier.

I'm assuming it would be better to purchase the 500 watt per channel emotiva so the speakers won't suck it dry or stress it. 

Am i wrong in this assumption?

Don't worry about the 300 watt rating on the speakers. That is a max level and no indication of what is needed to drive them in a particular sized room. If you can attain the volume levels desired and are happy with your amp/speaker combo then enjoy.
Moskaudio, am I to understand that you are now considering replacing both the speakers and the amp and going to a 2 channel system? If so I would suggest that you search out the desired speaker first, pair them to your Rotel stereo amp, which seems as no surprise to me to be superior to the Yamaha AVR, while your explore the market for an upgrade in amplification. Finding speakers that are at least moderately easy to drive maximizes ones budget towards amplification.
