Query: Great sound, but not long lasting

First let me start by saying, I LOVE these speakers. They sound better than more expensive speakers from several manufactures in the $200 range, including bose.However, they have a ~2-3 year lifespan. Mine failed after 4 years (with hardly any use), and after looking around the internet, these speakers are notorious for their short lifespan, and most people have a failure by year 3. The amps just blow out. The new ones have a new cheaper amp design, I would not feel confident purchasing them.
