All parts have technical life times, usually 3000-5000 hours for decent quality caps. Unless the amp was used THAT long, it's not a concern and if it becomes one, just replace the caps. 
but for the HeadRoom products,the cap can replace by yourself?not so tiny chip inside?
You'll just have to take a look inside and find out for yourself.
