Is There any Consensus at all amongst Audiophiles?

I remember once reading somewhere that theories in science don't necessarily disprove and succeed each other - merely that when proponents of less popular theories die they often take their theory with them.

So even in science there is no absolute right or wrong, merely an accepted consensus which can change from day to day. Much like the butter or margarine debate which has seen both sides on top at one time or another. Sometimes even old forgotten theories eg Flat Earth, can attempt a comeback!

However this lack of consensus only applies to cutting edge science. It does not mean that the vast amount of accumulated scientific knowledge is held in contention. Indeed there have been no major upheavals in scientific thought for almost one hundred years. 

And that despite the rise of the internet age.

Anyway, it would be interesting to see whether there is any consensus at all in the world of domestic audio playback. Very little, if the past few years of this forum are anything to go by. Professional audio on the other hand doesn't seem to have the time or stomach for this kind of endless navel gazing. 

But still, there must be some consensus in domestic aydio - there must be. Otherwise we're all doomed to die endlessly disagreeing with each other. Perhaps it might be easier to get the ball rolling if we can all state what we actually believe in. Perhaps.

I'd like to start by saying that err... this isn't easy. Hmm.. how about me saying that increased bandwidth (20Hz-20kHz) is a good thing?

Surely we can all agree with that, can't we?

What else is there?

Loudspeakers have a greater performance impact on the delivered sound than other components. Even more than other transducers like headphones and cartridges.

How about adding that this is because loudspeakers exhibit over a thousand times more distortion than the rest of the audio chain added up together?

Instead of constantly bickering, which we also enjoy, it might be of some interest to see what we actually believe in.

This might be more difficult than knocking other opinions (and less fun) but who knows, it might even make us consider different opinions, if not quite abandon our own.
