I am not sure why everyone on this thread is obsessed with your set-up. I will assume that you have a cart that is properly set up and that any new cart will be set up properly by you or a dealer. Yes, this is very important.
Like many audio components, some carts and phono stages are warmer than others. Not knowing your phono stage or cart, I can't comment on the relative benefit of replacing one or the other. Though it is usually said that the transducers, which convert physical movement to electricity (carts) or electricity to physical movement (speakers) are the most important parts of the audio chain, and these may also exhibit the greatest variability.
You may get some good warm cart and phono stage recs in this thread, but there should also be a number of other threads with recs that offer suggestions.
