This sounds like it used to be me talking to myself:
I probably have all the resolution anyone on this planet would ever want. I would like something rich sounding, excellent bass performance is a must as well
Use a Zoethecus Z-Slab shelf - these are available at relatively low cost from Stewart at SOS, & will bring out that rich warm bass performance that you're seeking, while not degrading the HF resolution which you've achieved. Click on my username & scroll down under the bio to learn more about how this shelf is setup in my system's digital stack.
