I had a similar experience with MIT interconnects..... I had a bad one and swapped it out with a pair of Nordost Blue Heaven. Night and day, it was like I pulled a blanket off my speakers. Crack one of those "Terminator" boxes open and you will find a 20 cent resistor and a 50 cent cap.
I swapped out my tuner , preamp to amp , and DAC with cables that do not have a "network" and I am hearing tons of high frequency information that was robbed with the MIT. FWIW I had a Transparent Link II that I cracked open the box and it was pretty pathetic what's inside. I took the other Link and put it between my sub DSP and sub and it attenuated the output.... so it seems they are not a pure conduit for the music.
