It seems that much modern portable and PC audio gear -- iPads, iPhone -- etc. don't incorporate "traditional" output protection (e.g., muting trans. or DC blocking caps).
I've heard that modern opamps and other ICs have built-in short-circuit protection, so no longer a need to stick to tradition.
Of course, discrete ckts and legacy opamps (5532) are a different story.
But frankly, even with older ckts -- and with protection bypassed (shudder!!!) -- I never had a DC accident. Of course, I can't speak for others.
All that said, and IAC, I prefer the sound of newer (self-protected or not) opamps.

How much could it possibly hurt the "speaker" in modern portable audio gear if the full battery voltage were impressed across it? How dangerous would that voltage be for humans?
"Real" amplifiers can hurt you or burn out speakers or themselves - that's why they need protection.
