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

Many solidstate amps will need to have their transistors replaced.This was a problem on some of the early Krell amps,their transistors would "leak" although they tested fine.Same with the NRG Control amps,though that problem was due to under-heat-sinking the driver transistors.
Hpoefully the devices you need are still in-stock.

As you purchase better & better ancilary components, a point is reached where the ancilary components become superior & the older components faults become evident. Nothing is actually wrong, but maybe that point has been reached.

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.
