Given that your dealer has proven useless, I suggest contacting the distributor, which looks like Focal Naim America, in writing. If the best they can offer is that you return the product to the country of origin, I’d ask my dealer for a refund.
If the dealer refuses, I’d take him and Focal Naim America to small claims court and argue that the product hasn’t met its implied warranty of suitability.
This all assumes that your dealer is an actual authorized dealer.
