I'm studying MIT cables

I'll admit to being a speaker cable skeptic, but at most the "box" is applying some type of filter to "color" the sound in a particular way (i.e. think Flowmaster mufflers where they all have a characteristic sound).

In theory, no cable is the best cable so I'm not sure what science they could possibly use to suggest that a powered "box" could result in an unaltered signal.

Open up a box and see what's really inside.

Sometimes moving up in a line does not get you the results you expect....for whatever reason. That was the case for me, I used many varieties of MIT and found the most enjoyable in my system was the 330 and 750 series.

As I moved up I found the sound either too detailed, or lacking coherency (which is the marketing mantra for MIT). I still use the terminator series in one HT system and 750's in another. But I have stopped chasing them in my 2 channel system.

As for the poles and input impedance and settings and the several dozen innovations over the years I can't explain and really don't have the appetite to try and figure out. I was using MIT before they had networks but after listening to other lines that sound better to me I have moved on. Not to mention they are über expensive! However, that's just me...YMMV.

I pried out the boxes in both designs and the switchable impedance type seems to have some type of circuitry secured down by liquid gel/glue. I took some images I can share. Pm me.
MiT revealed on their w/s what reallly inside the box of Oracle cables and it's truly amazing. Yall check it out.
MIT def have technology and r&d in their cables but, in the end, I still think they are way over priced.

I opened a the boxes on some 750 cvt speaker cables, and I found what looked like a tiny resistance glued on the stripped wires. The craftmanship was very sloppy to say the least, and there was really no need for that big box. Back then, 2004, these cables retailed for a lot of cash ($700-$1300). The cables ended up in the trash, and since then, I have used Canare for better conductivity at less than $1 a foot.
MIT, like others, are laughing their way to the bank(s) selling their gimmicks.
