Long IC pre to amp

Hi all

Looking for recommendations for a 15ft interconnect to run from an Audiopax Model 5 to Audiopax monoblocks.

I have read a number of threads and it seems I need a well shielded low capacitance IC. Balanced is not an option.

I currently use Tara Labs and ASI Liveline cables.

Prepared to pay so that sound is not degraded - some have talked of rolled of highs with longer ICs.

Thanks
