M60-$800
VP150- $350
QS8's- $470
HSU STF-2- $399

Total: $2019

The difference between the quality in the speakers (M60 vs M50, VP150, vs VP100, QS8 vs. QS4) shown is more impressive than the difference between going to 6.1 vs 5.1. Remember, there is no tax and free shipping with Axiom's speakers, I do not know about HSU's policy.

I have heard the M50s and own the M22's. The M22's are a much cleaner speaker according to the listening tests I did. And the M60 is supposed to sound just like the M22 only with more bass.
