Help with inverted phase Newbie Question


Hello,
I have a cary slp 30, which I have been using for about two years. I recently have heard that this preamp has an inverted phase. what does this mean and what does it require me to do to get the full sonic capabilities?

If your preamp inverts phase on all inputs (some invert just phono, some invert just the line stage and some invert both), the easy fix is to swap the speaker leads (instead of red to + and black to -, connect red to - and black to + on BOTH speakers. Voila, your system no longer inverts phase. You should note improved soundstaging and bass, except on recordings which are phase-inverted.
Edesilva's response was right on the money, so the answer is no. But, where did you get the idea that inverting phase reduces hum?
Jshaw,

This thread is about absolute polarity, AKA The Wood Effect. You are talking about reversing line and neutral on your power connections. It is generally recommended that, on equipment with 2-prong AC plugs, you should use the direction that sounds better, or if you can't hear a difference, use the direction that results in the lowest AC voltage reading from the equipment chassis to ground. With 3-prong plugs, the only way to do this is with a "cheater" (an adapter that plugs into a 2-prong outlet, with or without a ground lead). I am strongly against using these to lift the ground because of the safety issue, not to mention that your after-market power cords will not do their job properly without a good earth ground.
