Can the sound of SS amp deteriorate over time??


Would like to know if the quality of the sound of a "high- end" solid state amp can deteriorate over a period of 10-15 years. That is, the the bass sounds less tight and controlled, the sound is less clean and clear and imaging is less focused and precise. I realize that a tube pre-amp or power amp are subject to this deterioration in sound depending on the quality and condition of the tubes.... Need some technical advice

Some companies recommend re-capping them after 10-15 years. As electrolytics age the amp will become "thin" they say.
I'm not sure why this isn't a consistent practice though, unless it's design related.
Companies such as Naim Audio recommend that capacitors be replaced every 8-10 years. It is a regimen adhered to by legions of Naimophiles.
Bdgregory and Soulbrass are correct. Electrolytic Capacitors do dry out eventually, reducing their effectivness. I would imagine decrease in sound quality would be the first to go, followed by eventual failure. Electrolytics have a conducting liquid inside, sort of like a so-called 'dry' cell battery, but the capacitor liquid is less viscous than a battery.
