How can the AD700 be decent for rock if it has a good soundstage and no bass at all? o.o"
XB500 is supposedly more bassy (as in quantity and impact) than the XB700 while the XB700
has better bass quality but less quantity and impact. I think.
For bass, sure, get the XB.
For soundstage and stuff, get the AD700.
But neither will give you what good rock (imo) gives you,
which is epic electric guitar presentation, vocals, and the right amount of bass
to not overpower everything else.
