This is definitely a must buy. As stated above, I have a Hsu STF-2 and an Axiom EP175, and I have never felt my couch shake. Maybe the occasional rumble, but nothing on the order of what was going on in my living room last night. I'll be buying my copy tonight when I'm out picking up the Thanksgiving steaks.
