Aurender Music Server and CD Transport comparison

I am in the market for a CD transport and I want it to sound as good as my Aurender N100C. How far up the chain do I have to go to get sound that is equal or better than my Aurender? My choice so far is a Jay's Audio CDT2 Mk3 but could I go to an Audiolab transport like the 9000CDT? Should I go as high as the Jay's Audio CDT3-Mk3 I don't want to spend anymore money than I have to since the more I spend the more I get diminishing returns.

The system is Aurender, NAD M2 Digital amp, B & W 805 D4 standmounts.
