When I setup my JansZens my trial and error took about 5 minutes since it really didn't matter a huge amount. They are very easy to place and get great sound. Like many setups, observing the equilateral triangle is a great starting point. Mine are now about 22" off the wall giving a great soundstage but as was said, they can go right against the wall if necessary. This flexibility and smaller size created enough curiosity to look past my Maggie 1.7s, which I liked and still think highly of, and not even consider larger panels like Soundlabs. The sound from these sealed the deal. Buyers clearly don't need any help in setup. Requiring help and charging for it would be two red flags for me.
