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

I am not surprised a bit that bass is often discussed. According to dr Floyd Toole, getting the bass right is 30% of your system success. With the works of dr Earl Geddes, this 30% became totally attainable by the common audiophiles. With the effort of Duke and the Swarm, it’s even relatively cheap.  But, it still requires some work. Just dropping four subs in your listing room will get you about 60% there. So that’s 60% of 30% or about 18% success. A little DSP, a dash of acoustic and some elbow grease should push through the finish line. 

Not in any order, but I agree that cables generate the most heat, or do they?

Pretty sure that hi power tube and class A amps generate a lot more heat........

Hot Topics? Hot Topics? 
I love Hot Pockets!
Oh, uh...uh, oh, never mind.

     Anyhoo, isn't it about time someone chimed in on this thread and extolled, at excruciatingly excessive length, about the virtues of multiple subs?
     As you cats are well aware, I can do this in your choice of formats: backwards, forwards, metaphysically or in my sleep. 
     Please let me know when you get the overwhelming urge for another dose.

I love you all,

     Sorry Erik and all, I didn’t think my last post would stop this fine thread in its tracks. My intent was purely to inject a bit of humor, but apparently, this bit was considerably smaller than I thought.
     C'mon guys, I was even making fun of myself.
Please carry on,
Tim

Sorry to discredit your power to stop a thread dead in its tracks Tim ( which I am not doubting for an instant...lol) but this time it was Agon itself not you taking a huge dive.
