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.

Yes it will. It buffers the signal and uses it's own clock if there is any jitter it's not perceptible.

The Benchmark DAC 3 distortion and noise level  is -140db no need to worry about jitter induced distortion.  This is true of competently engineered modern DACs. There are even a few R2R DACs that manage to keep distortion and noise below human audibly but I wouldn't waste money on them they're overpriced. The RME ADI 2 FS is very good DAC that's cheaper than the Benchmark.
