There’s a reason why you pretty much never see measured documentation of wire "burn in" (or see it demonstrated as audible).
For one thing, it’s a rather convenient idea for sellers to promote "Don’t like what you hear? It’s not our gear, it’s a lack of ’burn in.’ Give it hundreds of hours !"
It gives you a chance to get used to the sound and voila...often enough it miraculously "improves," where what is most likely happening is you are just adjusting to the sound of new speakers. You may not adjust enough in the end and want to send them back, but this "foot in the door" technique is a time-honored one in sales: if you can get a product in to a customer’s home part of the battle is won, hence lots of ’try at home’ policies. And the longer you can put off a return, get the customer to keep the item in question, the more likely they won’t end up returning it. Suggesting a customer live with the item for hundreds of hours instead of making a flash decision to send it back is a helpful sales strategy.
I’d just be very cautious about depending on audiophile lore to fix your problems.
