I read this thread with some interest as I am upgrading my DAC and am interested in the question posed.  It sure seems to me the question was answered in a durect and helpful way, and the original poster is somewhat belaboring the point after receiving the answers, maybe not hearing what he wanted to hear.  We who use the internet and internet forums to get assistance for our own uses should have some basic research and searching skills to get more information to satisfy their curiosities.  Especially since we all know that there is a great deal of misinformation on the net, and who knows who has what stake in giving their answer.
further inquiries to the manufacturer of my DAC, (Benchmark DAC 3B), I have this response....

From engineering and designer of the DACs:

 

 

Yes, the DAC1, DAC2 and DAC3 converter have the UtraLock, UltraLock2, and UltraLock3 jitter attenuation systems that remove incoming jitter. There is never any jitter-induced distortion no matter what cable length is used.

we can chose to believe what we wish, and/or trust our ears....thank you

Facepalm is right, geeezzzzus.  Your response was totally neutral in asking for additional info out of curiosity.  Nothing more.  You weren't asking to be spoon fed, cripes.  This read like some road rage.  Just keep scrolling.

Anyway, as others have mentioned its really always about implementation.  Way too many variables to say interface X is the best, its impossible.  Inquiring to the manufacture is probably the best place to ask as well as providing them you workflow/signal chain => if you do a lot of hi rate up-sampling for example, USB/i2s is usually the interface of choice.
