I'd keep it simple... When you add the preamp to the 91XG you expect the signal metering to indicate either improved signal quality or perhaps no change... You don't expect to see severely degraded performance. (It's possible that the metering may show a small bit of signal quality reduction if you add an amplifier and no additional cable or splitter loss... This is because amplifiers add a small amount of noise.)
If you want to try the preamp on the C2V, the same is true, either improvement or change is acceptable, but not degradation of signal quality.
Rather than adding attenuators at that stage, use the the loss of real cable and a splitter. Remember, the job of the amplifier is to overcome loss due to cables and splitters... So, a good signal from the antenna, though an amplifier will be able to travel through more cable and splitter loss than the unamplified signal.
Save the experimentation with attenuators on the AC7 for when you have proof that the AC7 is reacting poorly to the cable impedance... You may find there is no call for any attenuators at all.
