How does MIT vary the impedance of their cables?

peleon: you can get into the mit network box if you really care to. all it takes is a sawzall, a cold-forged chisel and an 8 pound hammer. 'course if you take this route, you should be prepared to discover that there's nothing to it but the epoxy resin. -cfb

Any guesses why a cable company would bury passive components in epoxy?

Sincerely, I remain

Clueless,

Unless I'm mistaken, most speaker crossovers are "buried" in epoxy to improve performance by reducing vibrations.

Just a different, non-cynical, view.

TRH

Cornfedboy: Such cynicism about those fine professionals who bring us high-end cables. Can you prove that the epoxy resin they use doesn't improve the sound?

Thanks for the info so far guys. I didn't know that the circuits would be potted, but it shouldn't surprise me as it's common practice for any cable mounted circuitry in other non audio applications. The reason that it's done is to protect the circuit from shock, vibration and humidity when components are used on cables. As you can imagine real cables get dropped and banged around a lot and don't enjoy the privileged and pampered life that our "audiophile" cables live. Velvet lined presentation boxes, give me a break...
Despite what others say, I personally like the sound of my MIT IC and speaker cables, especially considering the prices that I have paid for them used. I knew when I bought these used 330's that I needed "low", but I thought for the price I'd try these "mediums" anyway. I can tell that they are better than the T2's that they replace, but the top end is veiled and compressed. MIT says that it's an impedance issue and I though that if I could somehow lower the impedance... Would anyone sell a Zobel circuit pre made for this IC application? I also now think that despite being bought used, they may never have been burned in so I'm working on that...
Thanks again.
Paul.
