seems to me the flaw in the op’s question is as much about how bad the prior dac was, compared to the new one
you go from the dull lifeless onboard dac in a bluesound node or a yamaha streaming dac to a decent (but hardly outstanding) high end dac like a denafrips ares or a topping d90, you may go ’wow’ ... maybe
but if we are dealing with 2 legit competent high end hifi dacs, there will be no ’wow’ - differences will be nuanced and subtle, if heard on a well conceived, properly assembled, sufficiently high resolution system
