Arnie... I fully agree, I was just trying to be funny...

I have tried A/B comparisons several times and I have not ever heard
any difference between an original and a 256K MP3.

At 128K they can get swishy...

Listen for stereo imaging changes. If you have a good speaker system that
actually images properly, it is very interesting to hear what the encoder
does to the stereo field. Stuff starts moving around.
