knghifi, MAD.... you bet! ;-)
8 of the MC-0.5s sound so much better than 4 that I am considering 12.
Better how you my ask!
Well... everything is much better... extended both top and bottom, but not only extended but smoother more natural highs and lower, tighter, crisper faster Bass.
More natural overall with much better defined soundstage, more depth and width and solid image, quieter more fine detail, more involving, more
musical, more effortless. The Magic abounds! No words do it justice.
I've been told by audio elite that my systems sound is rare and one seldom experienced in life, so to make it this much better is a real thrill.
YMMV depending on how MAD your system is.
Enjoy the Music! D
