No not really

The argument against your comment is that this excuse of breakin is BS. The excuse is being used to sell someone on speakers that they may not necessarily like the sound of. They take them home don’t like what they hear and go back to the person/store that they purchased them from maybe to return them, in most cases they would if given the opportunity take another model. In most cases a better/higher end model, but instead they are given some BS about the speakers breaking in or even better that the electronics have to breaking in, (in the case of your new receiver, Marc, remind me to never send some unsuspecting person to your store). The person goes home and get accustomed to the sound then suddenly they are OK and why? Well see because just like we told you they had to break in! Give me break!
