“Like anything in life, value diminishes as you go up the ladder.”
You must not have heard any good speakers. I can list numerous speakers in the $3k-$10k range that would blow away the double impacts.
I suggest that you attend a few good audio shows that have good systems starting with a few grand and work your way up to the $250-$500k systems and then tell me if there isn’t a huge difference in sound quality. I have speakers in the high 5 digit range and there are some very good speakers in the low 6 digit range that are better.
