Rip CD to Mac - basic question


I have started to rip some of my CDs to disk using a mac. I notice a lot of people using software to do this. When I look at a CD in the finder it appears as a set of aiff files for each song, for which I have been doing a drag and drop onto my hard drive, just like copying any other file. I would rather not use iTunes.

My question is: is this a bit for bit perfect copy? If so, why use other software? If not, why not? Computer files are always bit perfect when copied. There must be some software intervention on the part of the OS anyway, as a CD doesn't contain aiff files.

Any help would be appreciated. I don't want to copy a lot of CDs like this and then find I have to do it call over again.

Is there a way to convert stored iTunes AIFF files to XLD files?
Or is this just at the ripping stage for using XLD?
XLD is just a ripping application, like iTunes. Rip to AIFF or ALAC format with XLD.

If you are using a Mac then XLD or MAX would be the tools of choice for ripping CDs. In preferences you can determine the location of the files and they do not need to be used with iTunes. Some of the playback softwares used on Mac (Audivrana +, Pure Music, Amarra, Decibel, Bit Perfect etc) work in conjunction with iTunes (as the database manager) and some can also work without iTunes. I choose to use iTunes because I like the ability to manage my library that it affords.

Many people who use or prefer Windows OS will use ripping tools such as db poweramp. I think the most popular library and manager for Windows is JRMC (JRiver Media Center). Late this year JRMC will release a Mac version that should prove to be a very interesting tool especially for those who have Macs but may be averse to iTunes.

Well, I was talking about file comparisons. Of course, at the end of the day the whole point is to listen to the files, not analyze them, but now we are in the same situation as listening to amps or cables: some people claim to hear differences and some don't. It's all anecdotal. See my experience below.
So, I installed XLD at the weekend (thanks to those who suggested it) and experimented with ripping a CD to different formats (aiff, wav, flac, alac). I like the way it gives a log for the rip, that in my case showed no errors. I also like the way you can do a check on an already ripped file, which showed that the files I dragged and dropped also have no errors (though with an offset that I don't quite understand).

I would wager that these are all exactly the same, bit for bit, so it comes down to which format is most convenient and future proof. The lossless compression on a couple of them (flac, alac) is a nice disk space saver, and flac is most platform neutral, though not supported by iTunes.

However, to be frank, I'll be damned if I can hear any difference between the several file formats and the 2 apps I'm using (Amarra and Decibel) in my system, which I think is fairly decent (Mac -> Halide DAC HD -> Theta Casablanca -> Sunfire amp -> Von Schweikert VR-33 speakers).
