Burn in period

Burn in is largely bull. Purely preached  by marketers to leverage your unconscious bias.

@ghasley, while speakers (because of a moving part) might be considered to have a burn in period- it is generally known to be short - like minutes - and usually accomplished in the factory during QA. I agree that tubes also have a 'burn' in period - but they are a continuous burn down period till failure. As for solid state, cables, et al - I think it's marking bull - and designed generally to invoke what is known as the Ikea Effect (look it up). 

Show me some measurements with REW or similar to back up your claims otherwise.

@ghasley , but in the end it doesn't really matter - does it... if you have gained additional joy/pleasure through your investment in cables, subjective or objective, you did gain said joy. 

@ghasley, you could take objective measurements using REW or similar and post them here. Before and after. That would then be more like a science instead of subjective bias. 

What do you mean what would I measure? I would measure the frequency response from a logarithmic sweep signal from 20hz to 20khz from each cable and compare to see, if in fact, there is a difference.

I’ll get right on that.
