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 ?

Al is correct. I thought the preamp was a balanced design, however it is single ended. Reverse the polarity at the speaker end.

P.S. to my previous post:  In advocating a swap of + and - at the speaker terminals I'm assuming that the speakers are entirely passive, i.e., that they do not contain an amplifier themselves.  Let us know if that is not the case.

Having the system in reverse Polarity can be a blessing if you play CDs since at least half of all CDs are in reverse Polarity, at least according to the Polarity Pundit, maybe a lot more than 50%. There are no standards for Polarity.
