I named the MOBIE after one of my favorite bad movies, Maximum Overdrive....I called it the Maximum Overdrive Break In Engine or MOBIE and Tony used the name. I still have the prototype in the other room as I commissioned Tony to build it for me....Break-in seems to be much more voltage driven than current driven so not a good idea to stray too far from the load impedance it will see in use. This means that the 100 ohm load presented by the Cable Cooker is too low for interconnects, hence the propensity to "overcook" them and it is too high for speaker wire and it "undercooks" them...10,000 ohms is correct for interconnects and 8 ohms would be about right for speaker wire. I too have mentioned variable impedance to Alan, but it hasn't been incorporated into the design and not sure the unit will drive an 8 ohm load which would likely entail a complete redesign of the output stage....It would likely be easier to make two units, one for interconnects and the other for speaker wire, than try to make one that does everything......
