Input output cable question

Any hints of what I should get for a cable?  Favorites?

I see pricing from $200 to $6000.

I love to buy used expensive cables for more than 1/2off. 

Just a personal preference, but I like and use:

@bill_peloquin Ever wonder why the better than 1/2 price off market exists in such an abundance. 

No, there is no objective difference in sound with cables.
