I was using the WinZip as an example of lossless compression. I was not impling that we could use it on WAV files to save space!
As you have said, usng the proper encoder can save 50% without any loss of the digital signal ie APE, FLAC, WMA, etc
Anyone who wants to transfer their CD collection to MP3 (or whatever) should take one or 2 titles, rip them using various bit rates and sit down and decide which is the best for them. I did that and settled on the 320 VBR using the lame decoder. I think "most" people would be happy with that.
