Who knew if you moved speakers around it changed the sound? 
Did you see the speaker wire used? Looks like cheap came with my $50 speaker wire. Also how he stacked them, had them side by side, reflecting off a table.
Did he break in any of the speakers or amp? I know horn speakers (klipsch) can sound like poo when brand new, they need time to mellow.
I have no idea how he can not tell a difference between the lowest cost and highest cost speaker. No use of any SPL device to make sure you are matching volumes. Typically people will pick the loudest speaker, regardless of sound quality.
Really weird he found no value with the highly praised Kef's.
