Yes, double post, no IDGAF! Finally got a chance to use this bad boy in a mobile environment last night. It's an awesome piece of machinery, well built, has a real crisp and clear sound (no crackle or heavy bass). My only "complaint" is that I prefer the filter on my Pioneer DMJ250 as it doesn't cut the music as much, but other then that, I'm looking forward to learning much more about the S4! There are two different filter options you can chose from. Try the other one.
