If your Accuphase runs pin 3 as hot, which many pieces from Japan do, then yes, you need to either rewire the connector or flip the phase.
XLR connection between Accuphase and Denafrips
I am connecting my Denafrips Venus II to an Accuphase integrated amplifier E-380 via XLR connection. Denafrips spec states XLR pin 2 is hot (+) whilst Accuphase XLR pin 2 is Inv (-). Does this mean i need to select the phase button in either the Denafrips/Accuphase to align the +/- directionality between the two? I already tried combination of phase on/off amongst the two, and hardly could hear any difference. Do i need to care about aligning the +/- for the XLR connection between both or whichever alignment would do just fine and will not damage any equipment in my system for long term use?
