Knowledge and experience, and a willingness to be wrong, are the only cures for ignorance.
When the Duron 800 was new and shiny (in a greased aluminum kinda way), and the closest any PC around had to hi-fi was a generic Yahama GX soundcard, Xing had the answer. Audiograbber and a fast encoder.
Then my dad got a Hercules Game Theater XP (6.1). Then I got an odd motherboard with nice onboard sound (by onboard sound standards, that is

). I knew I needed better, but no $. Also, it was at this time I stopped any p2p dealings, as I dislike the typical quality as much as I dislike paying $15 for a CD. Yay for people giving their used CDs up for me to buy cheap

.
Then I finally got the $, and researched for a few weeks, coming up with the Philips Aurilium as my best bet, and about the lowest headphones recommended anywhere, the KSC50.
All was well, and I'd been lurking here for awhile. I had troubles encoding EL&P's Brain Salad Surgery (remastered). A few places in Karn Evil 9 - 2nd Impression, and 8 seconds into Jerusalem, sounded terrible. Thanks to testing methods partly learned here, I did my own personal AB testing, and it came out that in Ogg, the quality needed to be very high, else it sounded muddy, while in MP3, anything less than APE had a scratchy sound to it, not unlike the CD normally playing in a cheap setup (the synthetic organ bits can sound pretty strange on cheap speakers). With hardware compatibility, LAME 3.90.3 w/ APE it was.
Transparent lossy sound is just impossible, though. I don't care if you have golden ears or not, with a nice setup, you can hear the difference. This is quite possibly the hardest thing to convince anyone of without proof. Once I move out, I'll be using this site and others even more, as I must replicate, or improve upon, what my father got quite a few years ago. And maybe use some other sites to find the money for it

. Nothing but the real thing sounds quite right...but it also cost a pretty penny way back when.
Recently, I began to re-encode the entire combination of my dad's and my own collection of CDs (I haven't counted recently, but it was over 300 the last time I did count, around '94, so probably near 450 now).
After hearing some of the results, I figured I could stop lurking. I also have a weapon in converting anyone still using low quality xing encodes: Cosmik Debris. No song I have yet ripped has had such a difference made to it (nor has any album been as big--with APE, Apostrophe averages 290kbps). If you have the chance, encode it. Xing 128k vs. LAME APS or APE. It will put an immediate end to the misbelief of those things being CD quality--or even general listening quality--and won't require a long explanation of testing procedures

.
Though I do wonder...how can anyone believe that today? Have they never encoded something with the Xing encoder and experienced pops or chirps? 128k is one things...Xing 128k is another beast entirely, and much worse at grooming.
