Yes, Art. You hit it on the head perfectly.
For what it's worth, I was trying to be careful not to use the words "metallic" or "bright" when describing the LS50s, as I can't say definitely those adjectives are necessarily quite right when describing the overall character of the speaker. I don't think they are "bright", necessarily, as the treble region is actually quite soft. It's something right in the 5k-7k Hz range- a certain tonal quality that gives everything great clarity, but also sounds maybe a bit inorganic/limited in my system to my ears. Could very well be the limitations of my components and/or cables.
It`s not your system your just hearing what is there which others choose to ignore or cannot hear or reference. You are not alone with what your hearing with the LS50 i can hear it along with every audiophile that i know. It`s a blessing and a curse, it would be so simple if one were immune to certain flaws, but then certain joys would be missed also. Good Luck.
