I'm studying MIT cables

If you're still interested in MIT models better than your Magnum M3, I can share what i've learned thus far after similarly trying and enjoying the various additional musical nuances revealed by that same interconnect. in my system the sound of the M3 is clearly in the Maximum Articulation (MA) group of MIT cables, and not the 2C3D group. The immediate next higher model is the Magnum M2, and then M1. A big upgrade in the same sound style is the Shotgun MA models, and better yet at a higher price point are the Magnum MA's. When I asked my local dealer about a more affordable option for a speaker cable that combines well with the Magnum M3, he suggested the Matrix 18 Speaker Interface. It performed very well and is affordable. For those who don't know the Magnum M3 offers a huge bang-for-your-buck sound but even after break-in it won't open-up and sound impressive until after it is left unmoved for at least 5 hours, and even better after 12 hours. Good luck with your upgrading!

Hello Acompman, what's 2C3D group?

Oops! Forgot to clarify that my enthusiasm for MIT Magnum M3 being a good value is for the price used, and only if MIT's unique auditory advantages fit your system's synergy and your preferences.

MIT Cable's explanation of MA vs. 2C3D can be found on their website under "publications" and then "articles." My take is that since home audio can't yet fulfill the entire "absolute sound," we choose amongst compromises. MIT offers two contrasting designs to meet market needs/preferences. 2C3D seemed to provide an audio perspective that is highly organized and placed the music sound field in a space between the speaker's outside edges and backward in a wide rounded rectangle. Music was expressed with great precision and it was easy to hear and appreciate the totality of a song's composition. At times it created the tipping point whereby I could hear and better understand the artistic merits of some complex music (some symphonies and jazz). It seemed to enhance the ability to hear more clearly the individual parts and the whole of a musical performance, simultaneously. If I was an analytical music reviewer, I would want this style of system as a tool for my work. This style of sound could help audiophiles who need to accommodate others in their home. The sound is detailed and active at lower volumes, isn't harsh or edgy, but rather has a sophisticated tidy character.
In my system "MA" cables create a bigger and more dynamically lively sound, much more presence, images are large and have body, and instrument timbre sounds more organic and naturally diverse. Of course "Your Milage May Vary!" I hope this helps.

I'm weighing in late here because I just picked up a set of MIT Shotgun S3's from Joe. I have to say that the whole "poles of articulation" sounds like complete BS to me, but then, I'm no engineer, just a lawyer, :). What I can't argue with, and what matters most, is that to ME, for whatever reason and because of whatever mumbo-jumbo, the MIT Shotguns have hit a sweet spot in my system, replacing my Cardas Golden Cross cables. So with my Focal Diablo Utopias and Plinius SA103 amp and a Naim NDX (all my music is on my server), there is some sort of synergy that just "sounds right" with the Shotguns. Don't know why . . . Just that it does! :)
