Does a brand new electrical circuit for audio gear benefit from burn in/break in time?

Without breaking the bank $300 each for Furutech not necessary 

pangea  makes very robust outlets with excellent grip gold over Copper 

$50 to $100 each whatever you can afford . Very easy to instal even has a video

Thanks for relating your experience. Sounds like you had a good test situation. When I recently put in a new direct line, I noticed a substantial increase in sound quality, but not change after that. But I wasn’t paying close attention, but I tend to notice changes in sound quality.

Nope: no "burn in" effects.

I'll wager not one of the respondents fully disconnected their system and re-connected prior to the miraculous improvements...

@ghdprentice 

my experience too …. A new 20A line over a 15A line ( both dedicated ) provided a higher degree of slam right off the bat  …this was kinda expected somewhat with more amp headroom maybe, I guess ?

but nada further improvement after that .
