My Threshold service manual suggests reconfiguring the interconnect between preamp and power amp in such a situation: "important: any associated equipment that is to be connected to the balanced input of an E-line amplifier (i.e. preamp, crossover, etc.) must be connected with an appropriately configured cable assembly in order to maintain proper system phase characteristics." In other words, keep hot to hot and cold to cold. Then wire the speakers normally. Why live in doubt if you don't have to? Good luck.
Doubts on XLR config
I have a full XLR system. The pins for DAC and preamp are 1gound 2hot 3cold. I'm considering getting a poweramp with 1ground 2cold 3hot. I was told I have to reverse the red/black speaker cable to connect to the speaker. But would it be the same if I keep the red-red and black-black on the speakers end and instead have red-back on the poweramp side? My wild guess is there is difference. Reversing red-black at the speaker end is reversing the current flow on the speakers crossover. Whereas reversing the red-black connection at the poweramp is reversing the current flow in the speaker cables while preserving the original direction of flow at the speakers crossover. Anyone know what I'm talking about? I doubt myself. Thanks
