What do you all think of Infinity setups? Right now I have 5.25" fronts and 6x9" rears - reference series. I'm going to be buying an Infinity Kappa 255a 5ch amp and a Kappa 10" sub. I'm just wondering what the rest of you think of the Infinity systems compared to other brands. I've only had the opportunity to really hear a few other brands like Blaupunkt, Pioneer, Jensen...... just wondering how it stands up, even with the new big boys like the RF Punch series.
