Hi, thanks a lot. No I'm not an audiophile really, I just listen to music.
I understand treble and bass, but I still don't get what roll off means. Does bass roll off mean that the bass doesn't extend as low or isn't as loud as the rest of the spectrum? I know "attenuation" means reduction in X. Does that mean bass roll off is a reduction in the bass spectrum?
The word "lean" and "leaner" sounded like a positive connotation but from your description I imagine a leaner sound signature is not as good as a lush sound signature. Sort of like a (lean)lawnchair vs (lush)sofa. Is that somewhat similar?
To both questions, I say yep and yep.
