You should be able to get the total capacitance in these cables from the mfrs specs. Too high a capacitance might be affecting the ability of your preamp to drive these ICs? (You should be able to get a 'recommended maximum' from Tempest ... some other coax cable may have lower capacitance?)Secondly, if the Zout of your SS Tempest preamp is a lot less than 1/10th of the Zin of your Kraft 250 monoblocks ... then you probably don't have a problem with capacitance-induced HF rolloff. :-)) If it is less than 1/10th, you certainly will. :-((
Just FYI, due to the layout of my listening room I run 35' ICs between my preamp and active XOs ... and, to my knowledge, do not experience any HF rolloff.

Andy
