Even with a high-quality audio system? Nice reply!
Adjustments might need to be made. When I originally did this in my truck (put a majority of my music on an Ipod), I definately noticed how bad the Ipod sounded when compared to a CD. My first rips were done using Windows Media Player. One of the fastest encoders I've ever seen, but at even 320 bit rate it sounded bad.
I started using different rippers and encoders and finally settled on the combination that I currently use. The way I would test the sound quality was to put the CD in the player and switch between the source and the Ipod. When I could no longer hear the difference I was there. My quality setting is VBR 2. I have begun re ripping all my music using even one setting higher or VBR 1.
Also Lame can be used as an
external encoder for even more control, The following commands
-V2 --vbr-new or,
-V1 --vbr-new or
-V0 --vbr-new will produce great results. Other commands may be entered to adjust for personal taste.
Now MP3's are only as good as the source they come from. Only rip real store bought CD's. We don't know how a burned CD was made. Was it compressed first, then uncompressed and burned. Thats bad, depending on the compression format. In most cases lost info cannot be recovered. Making an MP3 from such a CD will result in a poor quality MP3 regardless of the settings.
Now if we are ripping for the purpose of archiving our music, then I would never recommend MP3. Lossless formats like WavPack or FLAC should be the way to go.
