Let's be a little meta: What topics are most hotly debated?

Fuses? Power conditioners? Analog vs. Digital? Class D amplification?


Nope.


The most hotly debated subject is bass.  What to do if you don't have enough, how to make it better, subwoofers, crossovers, EQs, room treatment.  Nothing launches more audiophiles out of there listening chairs faster.  Of course I'm guilty of this too, I've just realized that this is a subject with no end in sight.
