Sherwood receiver

the cheap consumer electronics these days it is hard saying , it sounds like this unit has had a easy life . more importantly than playing easy or loud is what is connected to it , small bookshelf speakers don't pull a lot of power but bigger speakers or highly efficient speakers would tend to pull more current . any how heat and being contaminated with dust and debris are probably the biggest enemy of electronics . i might add , if you were to need warranty service you might find the limits of the warranty require you to send this to sherwood for repair and they may reqire you to pay shipping back to you. that being said it may cost you as much as you paid to purchase to get service under the warranty . my advice to you is buy from abetter place next time , play the piss out of this one if you are still able to return it to radioshack and do so if it fails . otherwise you may find that a manufactures warranty isn't really worth anything to people in the real world.
