There are a lot of variables and the only way to find out how it will play out in your system is to try for yourself. Some of these DDC units are excellent for a pretty reasonable price, so there's low risk involved. Either buy from someplace with a good return policy or else pick up a second hand unit, and flip it if you don't end up hearing an improvement.
I like the Denafrips units and their Musician Audio counterparts, all very well built, great connectivity, and of course superb sound.
