I have been at the point, for some time now, that the potential for improvement is only there because someone continuously suggests that it exists. Otherwise, I would not pursue it.
Speakers have gotten better than my sense of hearing and judgement. I feel fortunate to have come to that conclusion, finally.
The best recordings are already coming across flawless with the uncomplicated speakers I have, IMO. My next upgrade will come when they standardize a more universally higher recording quality/rating. Some of it is getting ridiculously good as we move forward so, for 'my' use, the idea of a superior type of system is a little late to the game.
ETA: Cool stuff, though.
