Took one of the Polks in and substituted it for one of the Pi's on the NAD. Did a little left-right comparison having to quickly adjust the volume to account for sensitivity issues and the Pi's definitely put out more, lower bass. So we're OK there. Whew! Throw on the Kenwood and it put more bass out through both speakers (remember, this is what I've been used to for a longgggg time) but doesn't quite image as good as the NAD. So it's the amp! Could be that the 30 year old Kenwood is not actually putting out a flat signal with all the controls leveled out (and I usually bump up the bass and treble some), where the NAD actually is. I know with the Kenwwod I have to bump the treble up to 3/4 on the Polks for it to sound good to me. On the NAD I'm having to reduce it a bit so it's not so harsh on the Pi's and I noticed I had to do that with the Polks also. I think at this point I'll build some new IC's and see if that makes a difference. Otherwise I'm going to chalk it up to years of playing loud guitar without earplugs and my lack of exposure to decent equipment. When I think back, like I said before when I heard them at Wayne's, I checked them both with Norah this time and it sounded fantastic and Pantera was very bass shy until you cranked it up on the Pi's, but these differences were less noticable on the Polks. The Pi's are defintiely more revealing and think I like that better.

So never mind guys, it's an equipment issue and a brain damage issue evidently.

Thanks for all the help....Shane
