Why is there so much separation between the professional audio and audiophile worlds?

So here’s the thing.  5 years ago I had what most would call a pretty decent audio system.  McIntosh tube amplifiers, Willson speakers, great cables and connectors, a $10,000 turntable excellent CD player etc. When we moved to South America, I sold all of it.  When I returned to Canada, I purchased Paradigm 3F speakers, NAD 300 watt power amp and the NAD M10 Streamer AMP.  The total cost, $20,000 Canadian.  $80,000 lass than my previous system.  The difference in audio quality was less, but not by much.  Pro Audio is highly overrated.  I think quality streaming is the future of audio.
