That video is funny because they clearly know that the problem with "High End" is that it is confusing and complicated for the general public so those people avoid it and buy a single thing they can plug in and be done with it. And yet the audio places make no effort to simplify the process or remove the crap that makes normal people's heads spin.
That's not much different than any other technical hobby though. If NewEgg had a retail store you could do the same thing with some random person coming in and saying their Sims run too slow.
OTOH, it's not a perfect analogy because you can at least buy preassembled TOTL gaming PC or laptop if you don't mind a ~100%+ premium.
On the gripping hand, with PCs the products at least come in the same form factor, which I think is the real problem. Most people don't even want separate speakers these days.
