Yes sledge I have and at 10 feet it is not worth spending more money on another 50" set. The marginal increase in PQ and I mean marginal at 10 feet plus viewing distances, is not worth the extra money for me. I have no interest in a lateral size move. I have gone from 34" to 42" and then to 50", all when the prices became acceptable to me and the wife. Now at 65" I am very interested but not at these price points. Perhaps in a year or two. Frankly, I also have an older Panny ED set in the bedroom, a 42PWD4UY and guess what, it still has a great pic all these years later and was well worth the money at the time.
Louder is NOT better!
