No interest in Foobar?!

Man, you are truly missing out on an excellent audio player!
(1) The original poster made it clear he had no interest in fb2k.
(2) The topic isn't a discussion of audio players, but rather it's about integrated or plugin ABX test tools.
I agree with rjamorim and amano on this matter.
I haven't heard of an ABX tool for Winamp, but I wonder if anyone's tried to create such a plugin. The one with foobar is, as far as I know, integrated into the application engine, so there wouldn't be a plugin that could be converted to WA.
It doesn't seem like it would be too difficult for a programmer to create such a thing, though. Send two tracks to their appropriate decoders, incorporate adjustable offsets for the output, and then have a simple ABX front-end. Two tracks going to the same decoder can be handled by allowing two seperate decoder sessions simultaneously.
With the general popularity of Winamp, seems like it would be a worthwhile venture (considering enough WA users also wanted an incorporated ABX tool). Benefits would include the ability to ABX various processing applied to music at the time of playback, and testing multiple output devices as well (if different output plugins could also be selected for each track).
