I sold my ATI AT3005 amp about 2 weeks ago for $2K cash.
The guy who bought the AT3005 grabbed one of my SX-T1/R speakers and lifted it up a little.
I thought to myself, "Okay, he's buying my amp so I'll let this slide, but sure wish people would refrain from moving my speakers!

"
Back when I had Salon2, 802D2, Orion, and Phil3, some people would try to move them back/forth also.
