Indeed it was. And in fact, i urge everyone to form their own opinion. Find a way to do your own test like in the video, and see what your ears tell you. Mine tell me the same as in the video, but yours might not be the same
As someone who owned a Bifrost Delta-Sigma that I upgraded to a Multibit, I do have a bit more insight than some here! I did not have them side by side to compare so I can only go by memory, which is clearly not in any way a scientific comparison. I believe there is a small, but noticeable difference between the two (but concede it could be confirmation bias). There is always the law of diminishing returns as you move up the audio food chain where you pay a lot of money for small improvements in sound. There are also a lot of "voodoo" type claims for some things (not sure anyone can really tell in a blind listening test that a $2k power cord is "blacker" than a quality $20 cable).
