"electrolytic capacitors go downhill in such a way that you don’t realize it until the quality of audio is really bad."
Very true o10. But that condition applies to several parts of an audio system; vacuum tubes weaken as they age (and sometimes get noisy), styli (needles) wear and lose detail, speaker cone surrounds can disintegrate (particularly foam types), and electrolytic caps (in particular) and other electronic parts can drift out of their specified values. So does this mean we all need to buy new systems every 10 years or so? Absolutely not. But we must be aware of the limitations of each part in our audio systems. Even CD players can fail if the laser burns out. But then it won't play so you know it's time to change. ;^)
In fact there are many older components which can still offer very good performance, and not just the expensive ones like McIntosh or Audio Research. But the owner must expect to perform, or have a tech perform, certain parts upgrades to renew performance. In some cases, like certain capacitors, resistors, or transistors, performance can be improved over what was available when the component was new 10, 20, 30 years ago.
It is no different than our cars, or other appliance. Some maintenance must be expected. The real question is are we better off having the older component restored, or recycling it and buying something new?
