I'd let that be your guide. If nothing's wrong, don't fix it until it breaks! If it's for a customer, either they'll accept the engineering advice that nothing needs doing to it; or if they insist then you'd have to charge a convincingly gigantic price for the great labour of doing so.
Besides, there's a lot of nonsense written about 'capacitors in the audio path' which I think comes from America, in the same vein as stevehertz's post. When one stops listening to the music, some imagined niggle of dissatisfaction means money must be spent on changing hardware, or taking tiny measured differences in radio frequencies and believing there's an audible result.
If that comes on strong, it's because I've made the mistake of fixing something tiny until it breaks. Shipwright's disease is debilitating!
