I expect good quality and expensive hi fi equipment to last for more like 50+ years to indefinitely with sensible servicing as required. Gear like the stuff being discussed above will be skip fodder in 10 years ish. Hi tech digital parts etc have a short production life, are generally nowhere near as reliable as "old skool" analogue and in many cases there are things such as PIC's which have the manufacturers source code embedded in them so even if you could get the part it would be a blank, without much prospect of getting the code for it.
As GT pointed out, such tech can be very electrically noisy and is often a compromise on sound quality in comparison with best practice, honed over many decades.
