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

point taken

i guess one needs to balance being nice and telling the truth

Works for me!

Bass? Hmmm, I thought sure it would be either McIntosh products or cables. 

Cables.
Standmounts v. Floorstanders
Connections
Integrated v separates
Tube v ss v d
Room correction
To sub or not to sub
To sub a lot or just a bit
Headphones
Speaker design
Isolation
Wood v metal stands
Surge, power condioners
Tweeter design
Marketing approach
To test or not 
Test but how
To tweak or not
Tweak but how
Digital sound
Media preference

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

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.
