How does MIT vary the impedance of their cables?


Hi,
I have a pair of MIT 330's that are "medium" (47~100ohms) and I need "low" (10~47ohms).
I was wondering how MIT alters the impedance in their different versions? I'm guessing that it's with the use of a resistor in the network box? I thought that if I could open the box and jumper the resistor... Any opinions?
Thanks,
Paul.

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.

Pops,
I would drop MIT a line and ask them about the problem. I have corresponded with them on several occasions and have always gotten very informative replies. Good luck.
