Furutech is a good start in my opinion. Check out VH Audio for cables and connectors. Another good resource is Sonic Craft for Neotech power cables and connectors.
I’ve gotten good results with Furutech Rhodium connectors on two Furutech power cords I just put together. Very solid connection on both ends.
The break in was brutal but other than that nothing to complain about.
My First DIY Power Cable
Thinking of trying my first DIY power cable. Would like to keep it under couple hundred $$. Looks like it could be done with products from the Furutech site. Any other resource recommendations?
