The definition of "shilling" is of a hustler or con artist who tries to convince others to buy something that will benefit the shiller.
As a long-time (and current) Magnepan owner (first pair bought in 1973) that term does not fit me. I also own the Eminent Technology LFT-8b, which I thought the OP might like to become aware of. Everyone knows about the planar-magnetic loudspeakers offered by Magnepan, far fewer that Eminent Technology offers a somewhat similar (and imo superior) loudspeaker as well.
You got a problem with that? May I ask why?
