MIT network box switch position does matter

Some MIT cables have a network box with a 3 position switch, low, medium, and high, to match the cable with the input impedance of the gear. In another thread, someone mentioned that the center position gave them the best sound with Shotgun 3 cables.
For at least two years now I have been using Shotgun S1.3 balanced ICs between DAC to pre, SACD to pre, and pre to amp. My documentation states the input impedance for the amp is 38K balanced. The pre-amp documentation does not state the value. However, since both are by the same manufacturer, and were released as a pair, I assumed the pre is the same as the amp.
Anyway, 38K corresponds to the low position on the cable box, and that is where it has been set for at least two years, or whenever I bought these cables.
Tonight, I thought I would try the center position based on the previous post.
Big mistake. The highs and detail dropped off, and so did the volume. I had to go to -41db versus -45db, and even then it still did not sound right. After about 30 minutes I switched back to the low position, and it was good again. The highs were not rolled off, and there is much more detail to the music.
Apparently, the correct setting on the network boxes does have an effect on the sound.

The position of those switches can also have a dramatic effect on soundstage dimensions."He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche
