Seandtaylor99, I don't want to come across as an objectivist here, because I'm anything but. However, if audio gear overemphasizes attack, I wouldn't call that "fast" , I'd call that distortion. Truly fast gear will track complex waveforms precisely, neither lagging behind rising edges or overshooting trailing edges. Anything else is distortion, and while it might sound exciting, as you note it wears thin pretty fast.
So, while I agree with you about those edges (it's like oversharpening in Photoshop for those familiar with digital photo editing) it's not fast in the sense that I think our original poster was inquiring about. That kind of fast you just shouldn't notice once you've gotten over the initial "Holy cow that's good!" reaction. After that, it's just the recorded signal.
