Thanks guys. You pretty much just summed up my problem. I'm attracted to the relative simplicity of a Mac Mini system and I'm sure it will sound very good and that I'd be happy with it, but how much better can the sound get with a PC-based system and how much extra time and potential frustration will it take for a somewhat brain dead -- at least when it comes to computers -- audiophile to get there (I'm particulary interested in JPlay)? I'm willing to put in the work if the sound can be substantially better than a well-implemented Mac Mini system, but I haven't read or heard anyone with experience with both say that's the case. Anyone?
