DYI system that simply was never heard off


I am wondering if any members here have found the Holy Grail of their audiophile lives by doing something DYI. Be it cables or components, is there a company that convincingly produces kits or pre assembled audio gear that would make any BIG BRAND audio company the shame? Any feedback would be appreciated!

Clueless is clued in. Didja sell off all your stock in 2000 and retire, devoting time to your hobby? Wow, I'm impressed with the effort and quality of his post!

I think that most systems, diy or not, were never heard when they were off.
