Brf is correct, however, in most cases you will be better off changing the polarity on the speaker cable leads, switch black with red. The reason for this is that you may be running other sources through your Joule Electra preamp that do NOT invert polarity, CDP, MS, Tuner, etc.
That said, you need to know how your gear is wired. For example, my preamp inverts polarity, however, my CDP also inverts polarity. So I just wired my cartridge out of phase as Brf describes, and now my preamp inverts both CDP and phono back to absolute phase, so I don't need to switch my speaker cable leads.
However, if my CDP was NON-iverting, as most are, I would not invert my cartridge wiring, I would invert the speaker cable leads.
Does this make sense, or just add to the confusion?
