I take it you want more bass infusion on those. Try one of them CU4s. Another one I can recommend is a bit cheaper than the CU4 and that 198 cable.
This one is excellent and will help retain treble presence, wider deeper stage and not smooth it out like copper does. Most of all since it is 68% copper it is great at bass too, just as good if not better than the ISN CU4 actually.
I did a review for this cable and it is most definitely bang for buck one of my faves. These will go toe to toe with any SPC cable in the market and only cost $120ish. on Penon web site
https://www.head-fi.org/showcase/penon-os849-premium-iem-cables.24408/ I know this cable is above what most cables we chat about here but these are right there in the $100-$130 range. One of my absolute favorite cables to upgrade your sonics including bass. Why stop at bass when you can upgrade all of the sonics
