I want you to try to rip them using the FLAC format. I did it just now and after listening to the music ripped from a CD in FLAC format, I noticed how accurate and sharp the acoustic is. After listening to several music in FLAC, go back to listening any music but this time with your causal MP3 format. You will notice the difference between the 2 formats; almost 0% loss on FLAC.
For my case, I used dBpoweramp with a FLAC codec I downloaded from their site (somewhere). Unfortunately, dBpoweramp isn't free, so that's an issue. But the good news is that any Foobar2000 users out there can do this. Just follow the link here and you'll receive your FLAC! I haven't done this method so feel free to try it out.
