Slappy, I wouldn't say that I cannot appreciate the film on a system like yours, but I enjoy it much more on a system like mine.
My best friend has the BP3000TL and CLR3000. Keeping up with his bass is why I upgraded from my Infinity Kappa 9/kappa 8 combo to the IRS line. I think that my system sounds a lot better than his.
If you want to see something you can get for $30,000 that is a lot more than a small improvement, check this out:

I have one. It is so impressive that when people come over, they are blown away by my speakers (Infinity IRS Betas for surrounds, IRS V for mains) yet once they sit on the Odyssee and see some movie clips, they are MORE impressed with the Odyssee. It is not a small upgrade and there is no cheap version of the Odyssee (buttkickers are no more a scaled down motion simulator than a horse is a scaled down airplane).
As for a $50K HT, I passed that long ago and still find MAJOR improvements that I want to make.
