The reciever in question, the kenwood vr-6070 (I know, kenwood isn't fantastic, but i've been very pleased with it) is rated at an 8 ohm impedance, would running a vp150 (6 ohm impedance) cause any sort of problems? Or should I just stick with the vp100. The fronts will be m22Ti's, with qs8 surrounds and a Hsu VTF-2 sub.
