What uncontroversial audible differences cannot be measured?

It is, I think, a touch of arrogance to assume "live" sounds better. It really often doesn't, by just about any measure.  

I do not really care about arguments of whether live is "better" or not.  Better is too subjective and inclusive to be useful as a global parameter.  It is also too vulnerable to transient changes in mood and consciousness as well as program content.  

 

Live is what I want to hear and, therefore, my goal is getting my home experience as close to it as possible which, imho, is not achievable with only 2 channels.
