You need 2 thing's. First, you need to buy components from established brands that have a good reputations when it comes to service. I've seen many times repairs done out of warranty were still covered anyway.
Second is a good dealer. Always let them know you're having a problem, and let them handle it. You paid for that type of service when you bought the piece. You won't be bothering them. Any good store wants to do this for the customer. Most will even give you a loaner so you can still listen to music.
