Stockpiling Car Audio Equipment - who does it?

I'll admit it. I've got all kinds of new and used equipment carefully and neatly stored away at home. From what I hear it's a common symptom of the car audio addiction.

So I'm wondering what all of you have stocked away, whether you're just holding onto equipment or buying in stages for your "ultimate" system (pretty much what I'm doing).

I'll lead off:

Alpine CDA-7949 CD Tuner
Eclipse CD8051 CD Tuner
Alpine ERA-G320 EQ/DSP
Monitor 1 2.120 Amp
Xtant 3300x
Diamond Audio S650.25 3-way components
MB Quart QM160.03 Coaxials
Diamond Audio MacDaddy 10.8 Sub

And mind you, I've sold quite a bit away already. I'm sure this pales in comparison to the troves that others of you have, but I just wanted to prove to my wife that I wasn't crazy and that there are indeed others who do the same thing...
