If you're really into music, this is actually a bit outdated... it was, after all, written more than three years ago.
If you're serious about good quality, use lossless. Hard drives are large and cheap; a 250gig hard drive, which you can find for like a hundred bucks these days, will hold 4 to 5 hundred albums, losslessly compressed.
FLAC is a good format choice, because it has good tag support, and you can use it fairly easily from within EAC. There are others. They're all pretty similar in terms of performance, and FLAC will give you the broadest support. If you want to use iTunes, Apple Lossless is fine too.
I use CUE/FLAC files, myself.... a CUE/WAV is an image file (I use EAC to create mine), which I then compress with FLAC. I use this in conjunction with a couple of Squeezeboxes, which are well-built, have great displays, and really excellent sound. They use good DACs, and have a very low-jitter digital transport, if you're one who worries about jitter. (personally, I'm not sure it really matters.) They speak WAV, FLAC, WMA, and MP3 in hardware, and the server can transcode on-the-fly from other formats to one of these.
This gives you easy access to your entire music library using just a remote, so you don't have to be on the computer to start or stop music, unlike iTunes.
Slimserver's biggest drawback is probably that its playlist management isn't that great... it's a bit painful. Functional, but not drag-and-drop... this is iTunes' greatest strength, IMO.
Fortunately, Slimserver has the ability to integrate playlists and playback with iTunes, so you can, if you wish, use iTunes for management, and then use the remote on the Squeezeboxes to play your iTunes library.... as long as it's not DRMed.
Once you've ripped losslessly, you'll never again need to re-rip your library, assuming you keep good backups. if a new format comes out, you can just convert to that instead. You can put your CDs in a box in the attic and forget them.

So, to clear all this up,
EAC is a windows program that rips music off audio CD without compressing it.
FLAC is the best lossless audio codec,
LAME is the best MP3 encoder,
OGG is the highest-quality lossy audio codec,
Alternatively, you can just download iTunes and rip music without having to learn what any of those preceding acronyms mean.
Also, this post sucks.

I love those chaps who insist that concert recordings probably recorded on a cheap condenser mic onto cassette tape need to be losslessly compressed or they're worthless.
I love people who insist on lossless compression for their music library so they can listen to that glorious, perfect hi-fi sound in bud earphones.
They're nearly as funny as the people who insist that anologue vinyl is the only way to listen to music...music that was probably recorded in a digital studio in the first place.
It's music for christ sakes. Rock and roll. People with this kind of anal retentiveness prove that they've never known the joy of finding a dusty C-90 tape, warped by sun and spilt soda, on the backseat of their car and jamming it in the stereo for serious summer vibes.

I've found the best file size/loss balance comes from encoding with LAME VBR style: minimum bitrate 256kpbs, and maximum bitrate 320kpbs. if you can tell the difference between that and a lossless codec, then you can probably afford to buy the real CDs.

Actually, I'd like lower quality and much smaller files. I'm pretty much satisfied with listening to the radio (though FM is better than AM for quality obviously), and would survive quite well if my mp3s were that good. But I'd love to be able to fit a larger number in my music-alloted spaces.

Kickstart70: this is just anecdotal, but in the low fi range I've noticed that WMA can take quite a beating on file size and still sound decent (i.e., a 200k wma file sounds much better than a 200k mp3 file for 3mins of audio).

When you start out with a bad quality recording the damage done by compression is very noticable. You can lose half of what certain instruments are doing in the process, ie the drummer is suddenly only hitting the downbeat.

I spent a lot of time worrying about audio quality, compression, and headphones until recently, when I had the opportunity to compare a friend's Etymotic ER4's to my $10 Sony earbuds. What small difference I could discern I chalked up to the isolating effect of the earphones. At this point, listening to anything encoded at higher than 192k on headphones that cost me more than $30 is a waste of drive space and money.

monju, if the source isn't that good, then the ER-4s wouldn't show you that much difference. You should first compare the headphones with a lossless source and get comfortable with how they sound. Once you choose the one you prefer, then experiment with the lossy compression.
By way of comparison, I was checking to see what difference a headphone amp would make on my Senns. With 128k MP3, I couldn't hear anything different. Starting with LAME-encoded tracks at --preset-standard or extreme, I could hear a definite difference, and a bit more still with lossless. (I ended up settling on --preset-extreme for travel... it sounds great, and the filesizes are still manageable. )
If the source is crap, it doesn't matter how good your speakers or headphones are. Test first with a good source. Don't use a PC to choose headphones... PC sound, in general, is terrible. A standalone CD player, even a cheapie, will be a much better test. And remember that some models of ER-4 require a headphone amp to sound their best.... this is also true of the best of the Sennheisers. (580s/600s/650s). So you might verify that the headphone is being driven properly before judging it.
You may well find you're perfectly happy with 128K on regular earbuds, but to be really sure, you have to test the variables independently.

Malor, I was comparing the two with a lossless source on good stereo equipment. I, however, am a special case. I've had ear surgery 7 times, including a mastoidectomy and a reconstruction of my right ear drum. My ears are simply no longer capable of discerning the difference in quality above a certain point.

What Malor said... I ripped (and am ripping :) all my CDs into FLAC via cdparanoia. The upsides so far are the ability to recreate the CD more or less as was, and also that when I got a nano I was able to easily encode it all at a lower bitrate to fit more into the 4Gb (since the nano is mostly for commuting, where quality isn't so important).
monju, I have a pair of ER-4P's... the difference between these and the earphones that came with the iPod is truly outstanding. It's true that the isolation gives you a huge improvement before you even consider the transducers themselves, but the sound you get... it's just incredible. Orchestral recordings are so much more detailed with these than anything else I've ever heard that the cost (considering how much music I listen to) is well worth it.

Argyle, what if a new MP3 encoder comes out that gives you 10% or 20% better compression with better quality? Or even a different codec (say, if you're an OGG lover)? I agree that high bitrate MP3s are virtually identical to CDs, but transcoding MP3s will put an audible dent in the quality. The usefulness of lossless encoding is it only takes X hours of CPU time and (almost) zero hours of human time to change your mind about how you carry your music around.

If you use compressed music at all, lossless encoding is a good idea. I ripped my CD collection losslessly (EAC to Monkey's Audio) for two reasons: (1) to re-encode it later (without re-ripping) to MP4, MP5, MP6 and so on as standards change and technology improves, and (2) four sons and the tendency of my CDs to migrate away from my bookshelf, so now I can reconstitute the original CD. I don't listen to the losslessly encoded files. I play MP3s on my iPod, CDs on my stereo.
I like the Squeezebox concept, thanks Malor! Can you browse your music collection from one of these? How is the UI? (It's hard to tell from the product info on the site, and the remote control has no display.) This looks like a better execution than Sonos, and just as good eye candy.

Potentially lame questions for the audiophiles from a decidedly non-anal (but not totally indiscriminate) music-lover: Anybody have a rule of thumb about when it pays to burn in higher bitrates, and when not to bother?
I'd like to balance decent quality with a reasonable mp3 file size (I normally upload DDD CDs with VBR 192, and am happy with that) but I am wondering: Is it true that if you are ripping from an AAD or ADD source (say, a CD of a 1970's recording) it is okay (or even better) to rip at a lower rate, like 128? If the quality of the mp3 is ultimately dependant on the quality of the original source recording, wouldn't a muddy-sounding jazz CD originally recorded in the 1950's just sound WORSE on a very high bitrate mp3? Are you just magnifying the flaws of the original by making denser files from a flawed original?
Some people in the above thread laud the ease of iTunes to preempt all this techy confusions, and I can see why they'd want to. But to the techies here, how good (or bad) do you really think those iTunes 128 bitrate AAC files are?

Well, that's why you want to use an intelligent VBR algorithm like LAME's--the old crackly jazz recordings will still come out to ~128, but any parts of the track that need it will still retain fidelity. There's no really good reason to use CBR in this day and age, at least for the purposes of a personal music collection.
But you can't "magnify the flaws" by using a too-high bitrate. You can certainly make it sound worse by using one that's too low.

I should elaborate. Think of lossy audio like tracing a picture. You can't produce something that looks better than the original picture, you can just achieve closer and closer approximations to the original.
Using high bitrate CBR exclusively is like making Da Vinci trace Peanuts comics, a huge waste of talent and time.
Using low bitrate CBR exclusively is like asking a 5-year-old to trace the Mona Lisa--there's no chance in hell it's going to work.
Using VBR (as in the LAME presets) lets Da Vinci do his thing and the kid do hers, when it's appropriate.

ny_scotsman, I don't expect to ever need to re-encode my audio. And you shouldn't either.
New codec? Why use it? Maybe for new content I get... But is hard drive space getting more expensive? I've got over 500 CDs ripped to mp3 at 224kbps and it only takes 45GB.
My point is that in 99.999% of the listening cases, all of this futzing around with bitrates is useless. If you aren't listen to music in a quiet audio room with high end audio gear, you CANNOT tell a difference between any of the silly high end formats discussed here.
What's next oxygen-free silver cabling for your headphones? Vacuum tubes in your iPod?

Thanks darukaru... I really appreciate it. And a great analogy, too.

No, but is the drive on your iPod getting any bigger? I fully expect that (1) compression technology is going to improve, allowing for more music files in the same space at any given level of quality, and (2) I'll always be carrying around some size- or weight- or cost-limited storage device(s). Right now that includes an iPod, a cell phone and flash drive on my keychain, and I expect such portable devices with storage to become even more common. And more songs is better, I like choices.
applemeat, to answer the other half of your question, to my ear both AAC and WMA do a better job at bitrates 128 and below, so they are useful for some limited applications like streaming music over the web, but if you use VBR and a reasonably high bitrate, MP3 stomps them. There's just more music there.
