If over 60% of participants said the much cheaper set up sounded better or could not conclude which set up sounded better to them, it should raise uncomfortable questions in the entire HiFi industry and all those associated with it (including us).
In terms of audio quality alone the difference between cheap/easily affordable equipment and expensive ones may be far lesser than we believe. It may be worth revisiting concepts of “diminishing returns” prejudice, bias, and placebo effects etc.
At the very least it should prompt more investigation on the findings with better methodology to find out if this is replicable, reliable and why.

I also believe a lot of us in the “audio community” are invested partly because of the perceived “resale value” of our audio gear and at least a partial return of investment as we “upgrade”. This belief is comforting and Findings of such ABX tests can cause small economic tremors in our core.
Yes, I would call it a bit disturbing. (Or discombobulated?). The OPs header “Stumped” is simple, Crickety and describes the feeling best!
