I don't understand why everybody is always bitching/hating about the iMac speakers, because they do a good job! 😡
Most people still listen to 128-192 kbps MP3s, so what's the point in having cutting-edge and expensive speakers, if the output sucks badly!
Switch to a lossless format, if you want better sound quality! 😀
You'll hear a big difference, even with the built-in iMac speakers.
