I'm not on either side of the JBL or Heresy. I was interested in both before buying Forte 3's... I'm sure both rock and they get great reviews but like anything audio, gotta try it in your room with your gear to see if delivers the goods.
Regarding Robinson's JBL peeling veneer and rust complaint, that sounds like a humidity issue. Maybe he inadvertently exposed them to excess moisture or humidity? Unless he lives at the beach and has the windows open there's no reason why they would rust if kept indoors. He probably bought them second hand or he would have sent them back to the dealer he bought them (or JBL directly) for replacement.
Also, his reviews are crap. Thick with so much schmaltz and fluff and no real substance. Seems like he's targeting lower priced mass market stuff to maximize youtube views and page hits. Slick website, video editing and... dogs! (lol)
ugh barf.
