Hi, I'm a fledgeling sound enthusiast just getting into getting better sound hardware for my computer and so far, Klipsch seems to be IT in terms of speakers. So, I was wondering whether it was worth it to get the 4.2's or the 4.1's with the monster cable upgrade? As well, is there some place that describe's optimal speaker setups and any windows tweaks I can make to make sure they sound good?? I have an SB Audigy with ACS-54 speakers right now. The speakers are good, but I need some real "OOMF" and my current speakers just don't do that for me. Suggestions would be appreciated thanks a lot Anirudh
