Re: Line level IsolationYou can test for distortion with SMAART - just send in a sine wave and look at the RTA display. A year or two ago I got curious and went through most of the transformer boxes we had lying around. The only thing that was fairly clean at line level and 40Hz was a big box with big old Jensen iron that the owner had built back in the 70's. Even that Radial Twin-ISO didn't do much better than the Whirlwind mic splitters.
