The ecoustics article is okay, but two things stand out to me. The first is that it's written by the man who runs a company that rips CDs. So, of course your home system will never measure up... Read that info with a grain of salt.
Second. He mentions the different lossy formats, and the difference in sound quality that you get at different bitrates, but he never mentions the difference in sound between the lossy formats. For the same bitrate (using up the same amount of space on your computer) formats such as AAC and WMA will sound better than MP3. MP3 was the first, and it hasn't improved much. AAC and WMA use newer psychoacoustic models that sound better -- audible at 128kbps.
