how to get good sounding copies of CDs


I have just learnt how to copy CDs using itunes on my G4 Mac. But i am a bit disappointed with the sound of the copies.
I upload the original, using itunes AIFF lossless format, then burn to a (data) CD at slow speed(4X).The copies sound OK but lack space, air, dynamics amd sparkle compared to the original. They also sound a bit shelved down tonally.
Is there something I can do to make better copies or is this as good as it gets?
P.S.Playing on a rega apollo

I am not sure about Apple lossless, but what has been posted about FLAC is accurate, it is a truly lossless format.

However, major factors to consider:

First, the CD Drive you are ripping with and the mirror of the CD you are ripping from matter. In the PC world the program to use is EAC (exact audio copy) not sure if there is a MAC version of this, you can configure it to focus on quality copies and it logs the master volume level and how effective the rip was, IE what percentage of the bits were accurately captured. Some CD Drives cannot get to 100% so make sure you are using a quality drive to do your rips. Any scratches to the mirror, including small imperfections can affect the data transfer.

Second is media, what you are burning to is important, audio CDs buffer differently than data CDs and therefore what is good for one is not guaranteed to be good for the other.

Finally, to insure a true bit perfect copy you will need to make sure your ripped format preserves sample levels, DB adjustment levels and a CUE file to preserve gaps between tracks.
I have definitely noticed a loss in quality using itunes to make CD copies for my own use on a Mac G4 compared to making direct copies CD to CD using disk mastering software. Exactly as you describe, less sparkle and space in the playback of itunes generated disks compared to original factory burned copies of higher quality recordings. I have had significantly better luck using the program called "Toast" on the Apple to copy disks, and only use itunes to purchase and organize music as single songs versus full albums.

itunes does allow you to make a nice printed CD cover for your burned playlists to put in your jewel cases. Add the color album art if you purchased the music from Apple in the first place or don't mind Apple peaking through your songs lists to fetch the right art for the selected album.

In my experience "Lossless" does not equal no-loss. Better than standard MP3 though.
Rrm and Knownothing, out of curiosity, are you burning with a cd only drive or a cd/dvd superdrive? Are you using desktops or laptops?
Thanks to all for your responses.I feel like I should get an external CD burner(but which one?) and some better CD-Rs(again which ones: music.black,gold???)
Photon:My GE desktop mac has a CR-R/W DVD-ROM drive.BTW how do you burn your Cds on the Mac using WAV-I thought that was for windows?
Photon46,

I have a LaCie external CD-RW drive for burning. Does a great job, but sounds like a jet plane revving up on the runway when it is burning! I use my built in Panasonic Super Drive for the source - this arrangement seems to work very well, but I haven't carefully evaluated the reverse.

I use both PC laptop and Mac G4 desktop unit to burn disks from itunes playlists, desktop only for making disk to disk copies (I never loan out originals or take in the car!)

Question for all: Just downloaded several songs from Apple to my PC laptop and noticed that they are all 128kbps ACC files. I have read that Apple lossless is capable of 256kbps? Does this mean that I am not really using Apple lossless formatting? If not, how do I enable that within itunes on my machine(s)? Does format depend on the native format for the music file from the record label? Different capabilities running on Mac vs PC? Very difficult to get info from Apple on this.
