The title pretty much says my question. I currently have a stuffed Sony SA-WM40 and am looking at possibly upgrading. When I got the sub, i assured my wife that it would satisfy me, but recently I got a complete surround sound setup (upgraded from 2 Vega towers) and the bass is definatley the weak point of the system. I have looked at the graphs that people have posted and what not, but I have never heard a Shiva so it is hard for me to justify spending all that money when I haven't experienced "good bass" myself. I know this prob. isn't a real clear post, but I would appreciate some input. Thanks.
