Yes. Furutech gold-plated will be warm, with bass that is not as bight, but it does soften and roll-off the high frequencies.
Furutech rhodium will have deep tight powerful bass, but it will also have a lot of resolution and attack in the high frequencies. If you don't like high frequencies then this may not be for you.
You could try davidpritchard's idea of the Synergistic BLUE outlet. I have never tried this but it is possible that the BLUE could be smoother and more forgiving in the highs than the Furutech rhodium.
