The common misnomer that networked cables (MIT - Transparent) are filtered - is incorrect. The networks are paralleled across the conductors, not in series. Their purposes are (1) group delay compensation, as mentioned above and (2) to help absorb/attenuate reflected energy so as to prevent it reaching back to the amp, the amp's feedback then attempting to make erroneous corrections based upon those signal reflections. This also smooths out the detrimental effects of the inherent reactance charactaristics of cabling, ALL of which is reactive to some degree or another, making ALL cables equivelant to filters in some way, and thus interacting with the reactive characteristics of both the source & the load. This explains why synergy is so critical when trying to optimize your setup, and why a particular cable set works differently when placed into different electrical environments. This is an unavoidable fact of life for any cable. It is gratifying to see that at least *some* such as Dautch actually comprehend what is going on in that respect. Others who may install a component or cable into their existing rig (previously optimized for a different matchup) and then experience less than stellar results, are quick to blame the new device as a bad one, obviously an oversimplified & incorrect assumption.
In my particular case, my rig took to MIT cabling like a fish takes to water, realizing a lovely combination immediately, which only improved over a 30 day interval as the cables were further used (the breakin phenomenon). Bruce Brisson definitely knows what he's doing, just very misunderstood.
