nordost red dawn: problem, please help

all you smart guys:

i have been running an arcam A80 integrated amp biamped with an arcam P80 amp using nordost blue heaven version 1, 4 metres set up for biamping. i have had no problems running the volume up to very high levels. i just installed a set of red dawn version 2, 3 metres terminated exactly the same.
with the red dawn, at about 75% power, the amp driving the bass will shut down. it will come back, but the volume must be lowered.
the speakers are aerial 6's. they are not too efficient at 86db and are power hungry.
i can't live with it this way. if i can't find an answer, i won't be able to keep this and i think it sounds better from what i can tell.
help please.
thanks in advance.

Maybe you are playing at louder levels to compensate for the Red Dawn lean bass...this could trigger the amp's protection circuit as Stringreen pointed out.
OR the Red dawn cables are picking up RFI (they are unshielded and your amp is struggling to amplify the radio frequency.
Good luck
