Back to HiFi, I can say without any shadow of a doubt that classic HiFi was, and is, infinitely more reliable than the SMD/PbFree low cost stuff that has been churned out for the last few decades from developing countries.
I know through hole is dead for much of electronics manufacture, but the irony is, it will outlast everything that comes after it.
Where everything these days uses a micro to run everything, gear of the past used dedicated circuit elements for protection. Not passing the buck to the micro to monitor via a series of A/D lines and code.
I look at a 2 channel failed stereo integrated amplifier and it needs repair, then factory firmware, console/control software and a dedicated interface. Ridiculous, and offers no performance advantages whatsoever.
Bulletproof physical input switches and relays were replaced by a one-size fits all, AVR input controller IC which is fragile in terms of surges/spikes.
I have zero interest in owning (other than buying a few thing for curiosity's sake- not actual use) inexpensive Chinese audio. I don't call it high fidelity, because the term also encompasses long term reliabiliy, build quality, pride of ownership, ease of use, ergonomics in design and of course high technical performance.
I've also got enough real HiFi to last many lifetimes. For people who are starting out, with modest budgets, they may get into the game, but sooner or later they will do what our member further back in the thread did, and just get rid of the cheap stuff and buy what he really wanted in the first place: the Benchmark gear.
