Almost if you could visualize them as lasers rather than beams, but in a really engaging way... Tough to explain. Is this what people are talking about when they're talking about grain? Was I hearing grain in the HD600 but not in the Mad Dog?
You are the first person to echo what I have been talking about. The Mad Dog has very little "ringing" or "smearing", meaning sound that is added right after the note. It actually makes it sound dull at first listen, because we are so used to hearing that ringing.
It is similar to the "sharpness" control on TVs, that add extra high frequency content to images, which looks like buzzing that makes edges stand out more, which makes the edges look "sharper".
But in both cases, the extra ringing and buzzing is not part of the original, it is a distortion.
