  Im looking at hifimann he-400 with one of these cable options.  I love bass but with these being a warmer headphone, and bass heavy amp, would silver be a better option here to maybe balance the sound out.

Probably.
Why not try both?

You want to spend $200 on a cable for $400 headphones?  I'd suggest getting better headphones
