Kore Player isn't bad (well, it's free) and in a similar vein there's UVI Workstation
UVI Sound Source - High quality sound downloads for all of your needs It's still at the PB stage so 'may' be a bit buggy for some, but they've been very responsive so far in ironing out most of the bugs users have reported. It's free, only the extra soundsets need buying, tho' be warned, it installs pace, seemingly needed for the extra soundsets as and when they become available.
