Herman,

The most probable reason is that AQ is Cat-7 and you have been using Cat-5e. In Cat7, each twisted pair is individually shielded, whereas, I believe, Cat5e is not shielded (see a picture of Cat7 in Wikipedia)

It all depends on how long the cable is and which path it is taking. Which brings the point of MS200 - you might hear the difference if you move MS200 to where MS600 is. It might very well be that there is much less RF around MS200 as it is now located - thus less (or no) improvement.

Lastly, if you can, I would recommend that you purchase a regular Cat7 cable and re-try your tests. Even though AQ seems to have better metallurgy & connectors, the SQ difference might be negligible. A typical 3ft (~1m) Cat7 is about $3.50 here in US. Not sure how much AQ costs.

In the end, your ears should decide smile
