I need components to hang with my 13" w7 with a PPI PC class limited edition amp 4 channel, 400 watts. I'm looking to get the 6.5 components with a budget of $200 - $350 and rear fills to follow. I've been recommended diamond, focals, bostons and morels. What's the difference in these and which ones will give me the peace of mind I need. Thanks in advance.
