I use WaveShop, but nah, not really... I just have it but almost never use it.
Also, ALL of those things will change how stuff sounds. Maybe it was just mastered weird, too, or there's channel shenanigans with 5.1 stuff going out on stereo or less. Or something else. If you're on Windows, don't throw rocks at me!, remember to adjust the "predetermined format" to the highest possible for every speaker too. That's it.
Also, I meant to say you should check them with AccurateRip or CDDB or some other online tools, probably already included in your ripping software. If they pass those checks, then you have nothing to worry about, just do it twice for some placebo if you're very paranoid. If the disks are not on those, then your ripping log is all you'll have anyways, and there's no 100% surefire way to know it did the job right for every bit. But buddy, if the log says 100% successful AND the file is not empty and has the actual sound and stated duration... There's almost no chance it failed. Can't explain more detailed cases because this would get too long, but those files are probably already fine.
To test the different sounds I just try two sets of speakers, same config, maybe the cellphone speaker too. If they sound too different, then the problem is not the files, those are fine already. Some places appreciate those succ
