Upgrading interconnects?

Spaz, another cable you might give a shot is Harmonic Tech magic link II - they are more dynamic than MIT and Kimber, but retain the holography and imaging you like - might be what your looking for. I find they work best as a link between preamp and amp in my system.

Tpsonic,
("You might be amazed at what getting rid of passive components in the signal path can do.Akin to preamps and amplifiers.These components all contribute something.Correcting phase relationships after-the-fact doesn't make sense to me").

I thought that the network boxes act as filters.I didnt think they did any thing to phase..

Capacitors and inductors effect phase,as any electrical course will teach the student.Thus many of the equations have to do with phase angles/relationships.

Tpsonic,
When I think of "out of phase "like your saying,The imaging should be not focused and it sounds really goofy.I never got this from MiT nor any system that's wired by MIT.I'm Not following you on you statement..

I am not speaking of 0/180 degrees,as a subwwoofer filter/crossover.I have heard MIT and the filtering/Band Pass filters do effect the frequency spectrum/sound.Changing out to a piece of wire which does not try to do such sophisticated spectrum/frequency shaping may or may not be an eye opener.
The passive filtering may give a smoother top-end or fuller midrange/midbass,but I can't see how its' attack/sustain/decay characteristics would be better than a straight wire configuration,as a passive component in-line will contribute its' own signature.If the source component,pre or power amplification can't provide what is needed,then fixing it with a filtering network after-the-fact is much like a bandaid.You would need to know what you are trying to correct and not issue a "blanket" filter.As the filter for one system would not be applicable to another.
I don't know that I can explain this differently.It is something that must be experienced.Every system has its' own contribution to the perceived sound.Whether that is to the listeners' preference is another issue and its' adherence to the source yet another.
My two-cents:try it or ignore it.
