IMO no, but everybody's different. In my experience if receivers are going to fail they will do it soon after you get them. Once they run a while with no problems they are usually ok and if they do fail after the manufacturers 2 year warranty runs out you usually can replace them with a used receiver of the same or equal model for about the same cost as the warranty would have cost and you don't have to fool with the repair facility which can be a pain and lengthy, or more often than not by that time some new technology has come out and you're ready for and upgrade anyway.
Speakers as long as you don't over drive them and they are getting a clean signal or aren't abused in some other way will be fine.
