preamp inverts polarity


I have a DeHavilland Ultraverve 3 preamp that inverts polarity.
my problem is my speaker cables, the negative cable is designed for negative terminal connection as is the positive cable is designed for positive terminal connection, so reversing the speaker cables defeats the design of the speaker cables.

what am I to do ?

Just insert a dedicated stereo signal phase inverter between your preamp and power amp if switching the leads on your speaker cables fails to restore the polarity.
