Is there a maximum length for tonearm wiring?

In other words, the wiring that leaves my rega rb700 tonearm and plugs into my pre-amp is about 1 meter long. I would like to move the turntable further away from the pre-amp which would require wiring about 2 meters long. Is this less than ideal to increase the length of the wires to 2 meters? Would I lose part of the signal by increasing the wire length? Thanks for the help. George.
