consider the output impedance of the preamp. if it is above say 600 ohms, you may affect treble frequency response if interconnects are of high capacitance.
there may also be a cost factor. long length speaker cable may cost more than long length interconnects.
i personally use a 6meter interconnect and a 5 or 6 foot speaker cable.
