do i need a new DAC


i have a NAD D1050 which is now 5 years old but still sounds fantastic.  just upgraded my amp to the new Rega Brio 3.  was considering a Chord, Rega, or the new Audiolab MDAC+.  but i can't imagine it making much of a difference. for a DAC that is 5 years old the little NAD is holding up well?  what has happen in the last 5 years?  have their really been such great strides in digital playback made? i think SS is evolving faster.  any suggestions?
thanks,

Did the OP change out the power cord at least 3 times? How about the USB or SPDIF cable? Or the interconnects? 
If not, you have some work to do before you learn any DAC's limits.
A DAC not optimized is a shame.
