Wow I can sympathize. Sounds like you're discerning a S/N ratio problem that would have disqualified the designs from 'high fidelity' in the late 70s and through the 80s. And you have to wonder if in your TV/Apple the hiss is there but is being noise gated. I too believe there has been regression. All it takes is one generation to 'interrupt' consumer expectations of ever increasing quality. https://news.ycombinator.com/item?id=18569013 https://news.ycombinator.com/item?id=18569013

Not so long ago widely used audio codecs (the actual ADC/DAC part in the PC) had big problems with idle tones at low signal levels (which were simply gated off at silence, otherwise you would have gotten constant, looping artifacts). I managed to reproduce over 100 % THD+N with my old Thinkpad X200, i.e. more, very clearly audible, noise and artifacts than signal. This is a separate issue though from the usually high output noise floor and poor isolation from other components, e.g. many complaints about many makes and models where CPU/GPU or even disk activity will induce audible pulse noises in the heaphone outputs or speakers.
