It is a slippery slope - about what you can hear and what you think you can hear! I might grant you on CD transports, but once DACs come into the equation, well, I think I hear differences.
Your assessment of amplifiers probably applies in 95% of system situations, but likely not in real hi-end applications where speaker impedences (and sensitivity) and the ability to really generate low bass puts demands on the amplifier that cheap designs are unlikely to satisfy.
I recently replaced the 3-channel Adcom amp in my HT with a model from Krell, and while the differences are not enormous, I do get a quite noticable improvement in the bass.
As the famous philosopher once said (OK, maybe not so famous since I cannot remember who): 'just because you say there is a difference does not meant there is, and just becasue you say there is no difference does not mean there isn't'. Or something like that
