My system is a little higher end than yours and all the components have been chosen after careful A/B comparisons. It is generally revealing of all the various audiophile tweaks etc.. Earlier this year I did a shootout with 6 DACs, 5 owned and one borrowed. All of them were different but the differences were generally less than I think you would hear between other major components. And I am in complete agreement with
@LL21 post in this thread that extends this argument to the ultra high end.

Having heard the dCS Varese there is no question in my mind that you would hear a significant difference if it were in either of our systems but it costs almost 2.5x the new value of my system and 4x the value of your system and I also have no question that the extra money would be better spent elsewhere.
Finally, if you haven't spent a lot of time and some money upgrading the power, cables, switches, clocks and sources that connect to your DAC you should do so. I found some of those changes to be as transformative as the difference between DACs and at a much lower cost.
