Dac upgrade

Thinking of upgrading my ayre qx-5 twenty dac to a T+A dac .
going to audition it next week.
the mp 3100 hv and the hdv 3100 hv.
my system is ayre Mx-r twenty, kx-r twenty , kef blades, Jl audio f113 sub ( a pair) , cardas clear interconnects , speaker cables and power cords , lumin u1, ayre c-5xe 
appreciate any input on the t+a , read awesome reviews about them but can’t imagine how they can sound better than my ayre qx-5 twenty .
thanks in advance
