DJ Gaffle>>Sure, if most of your patrons are sloppy drunk, they're not caring about music sound quality... they're most likely trying to look at tail in the club. I've come behind other DJ's in sets who had questionable Limewire sourced music. Most of my music collection is ripped from CDs at 320K or from quality record pools. I've seen the crowd's energy increase with my better sounding, harder hitting music files compared to theirs. If you're the type of person that cares about your sound, you'd do your best to insure you're getting the best quality music files along with quality equipment. If you're the type that is playing on cheap Nady speakers, you probably won't notice or care about the difference.
So would you buy cheap shoes for your kids feet? ...They're just kids, it doesn't matter, they grow like weeds anyway.
Cheap tires for your wife's car? ...Nobody'll notice, they're on the dirty concrete anyways... it doesn't rain here very often either... she'll just need to go extra slow in the rain.
Cheap dog food for your dog? ...It's just a dog, he'll eat anything.
Now that was very well said, the fact that you've noticed the energy levels of the crowd increase because of your better sounding files says it all!I have found exactly the same thing thats why i'm constantly searching & upgrading my files with better sourced ones.
