sadly it isnt mine, its a group rip. can always buy the cd when its released and FLAC yourself. i have never messed with FLAC is there a difference in quality?
Well, that's really a touchy subject. The file you posted is a V2 lame mp3 rip, and a lot of people would say they can tell the difference in quality between that and a V0 mp3 or FLAC rip. So in this case, yeah it might make a difference.
As far as V0 mp3 vs. FLAC rips, most people would not be able to distinguish between them. Some people claim to be able to, but most of them are audiophiles who spend insane amounts of money on equipment that allows them to hear the difference.
Also, if you're interested in making remixes or using portions of the audio in other places, having a FLAC is absolutelly necessary. Tanscoding from a lossly format (such as an mp3, regardless of the quality setting) to any other format will always give you lower quality sound than if you sampled from a lossless source in the beginning.
So like going from a FLAC file to a V2 mp3 is higher quality than going from V0 mp3 file to V2 mp3 file even though the end results are technically V2 in both cases.
Anyway, most people don't have the equipment or the need for FLAC files, and I'd say sticking to V0 is a safe bet. I only asked because I was going to make a V0 rip of the FLAC and upload both of the versions to a private tracker so I'd get a nice boost to my status there :D
