To answer your earlier question, there's no point in making a Flac from an mp3. Flac is a lossless file format, you basically get a big file that contains all the information the file has on CD (redbook format) or greater resolution if you have a higher resolution original.
Track down the original on vinyl, record it at 96/24 and convert it to Flac. I've got a ton of 90's house and techno on vinyl, what are you looking for?
It wasn't a very well written post in fairness :)
