My advise is give the Musical Fidelity X10v3 with attendant power supply a try. It may well do the trick and not at any great expense.
I use one in my system & it brings warmth, much better dynamics; Increases fluidity as well as add a little bloom to the sound. I use the MF Trivista 21 DAC which is a pretty good DAC and even then, the addition of the X10v3 brought gains.
No real downside that I can hear. I thought it might affect timing/PRAT but it does not.
Hope this helps.
