Does removing "interface jitter" help, if my source has jitter?

I'm thinking of getting a Benchmark 3 DAC, and one of the selling features is its UltraLock3™ jitter attenuation system, which Benchmark says "fully isolates the inputs from INTERFACE jitter" (emphasis mine).   If my upstream source has jitter, will this system isolate that from the DAC?  My usual source is a Blusound Vault, and I suspect its jitter control is not as good as the Benchmark's.

Benchmark DACs and a lot of others as well, "truly lives up to that claim", since the measured distortion and noise is well beyond what humans would hear. So if I use the word "immune" that's what I mean and if it is jitter a USB cable isn't going to fix it.

Wish I knew *exactly* what jitter sounded like. My system might be so full of jitter that it sounds like a garbage disposal to everyone but me, but how would I know? 
Best (and first) answer I found when researching “what does jitter sound like” came from John - 2009: 

“Like the sound of one hand clapping”.

Jitter creates sidebands to each frequency at very low level.  With a lot of frequencies (music) it is basically noise added to signal (inaudible without signal).  When I switched from CDP to Benchmark DAC1 I had impression of great clarity, that it took me a while to get used to.

The fact that sound changes with different cables might not have anything to do with jitter suppression since every connected cable injects electrical noise - some more, some less.
