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?

I can see that. I figured a fairly expensive flag receiver would produce decent quality power but I guess I should try hooking these up to a 100watt per channel rotel amp I have and see how it sounds.

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.

What Rob and others said. Although, I guess he was joking about the Quads. Your rig sounds pretty good at high volumes but giving it bigger amps will only make it a little louder. You need to get better quality gear to make it sound better at lower volumes.
