Very true about the ET LFT-8b, @tomic601. But for whatever reason, no matter how many times they are mentioned, people just like the OP continue to ignore them. I give up! ;-)
Plus, as he was mentioning $500 loudspeakers, I didn’t want to suggest a $2499/pr model. Another planar to consider, assuming you have at least 3’ minimum (5’ better) to sacrifice behind them, is the $650/pr (plus shipping) Magnepan LRS, with one to four subs.
I would take either of the above before a lot of far more expensive speakers, but I’m a planar enthusiasts. Not everyone is. Planars are like Country music or Opera: you either love ’em, or you don't.
