So the question was - what is exactly different in $10K streamer as compared to $1K.
@mikhailark You’ve now been told by several experienced people here that things like parts quality, noise reduction, power cables, implementation, etc. matter in streamers. @ghdprentice who’s been in the IT industry for decades described many engineering types he’s worked with as having convinced themselves there’s no way in theory these things should make a difference and just hang their hat on that belief, and you seem to be in that camp. But he also gave you the best advice and that is, rather than just arguing why these things can’t or shouldn’t make a difference just listen — find a way to demo a better streamer and just listen in your own system and you’ll have your answer rather than continually raising this same point over and over based solely on theory.
