Phono pre "Break-In" process? Necessary?

The flagship Duelund capacitors that everyone is raving about are notorious for long break-in times, as much as 500 or 600 hours, so they say. Of course it’s always possible that some sort of group hypnosis is going on. ;-)

One High Fidelity Cables reviewer noted that the CT-1 ICs were 90% broken in after 10 hours. Well, I happen to be rather disenchanted with the whole idea of 90% of anything so it begs the question is break-in like recharging a cell phone for which the last 5% of charging takes the longest time? Aren’t we just trying to get the last 5% to get to the Promised Land?

wolf_garcia, are you merely fooling around and adding distortions to the soundtrack or are you searching to understand? I'd suggest, let your ears and your experience be the true test of whether something exists in the audio hobby/world. Trading ideas and experience can be helpful yet, to rely (or worse, depend) on measurements or someone else's convincing tale, is to miss the entire point. 

r_f…I do welcome the humorless as, after all, they are people too. I am astonished when an obviously ridiculous comment meant to break up the tedium around here results in officious "suggestions." My experience as an audio geek goes back to the 60s, I've been a successful musician for 5 decades or so, and mix live jazz concerts (and other stuff) regularly. Even based on what I've posted here you're response makes even less sense than my posts which often purposely contain nonesense designed to poke at the tedious gasbags who populate this place…welcome! 

Sometimes hard to separate those being intentionally ridiculous, from those who just are...

It's great to have both the musical background and audio experience you speak of. I don't know you, so I would not make too rash a judgement to whether that means anything or not. Hopefully, it has more to offer here than sheer levity. While old and young "gasbags" as you call them, create intolerable levels of THD throughout these discussions, there are those who actually don't understand and deeply want to. Ironically, I believe you and I ultimately want the same outcome here.

And thank you for welcoming me to an audio website that I've been on now for nearly two decades.

Still find me too sobering? :)

pbn - None of the articles seem to examine small changes over time nor do they remotely hint anything related to resonances.  And who's talking about electrolytics, specifically?  Definitely NOTHING related to actually hearing differences.

I stand on my earlier opinions.
