[QUOTE="Ampdog, post: 77201, member: 144"] All this is really very interesting to me. Simphiwes, I was hoping I might ask you to do a little experiment - will be a bit of a bother, but you seem to be in a position to do so. That is to listen for some time (say 15 minutes) to all four the possibilities. As you have them now I presume it is in phase. If you could then (2) change the phasing of loudspeaker A only and give it a listen. Next, if you could now (3) change the phase of the other loudspeaker B only. That means that they will now be in phase again, but of opposite absolute phase. If (3) you then could change the phase of loudspeaker A only, yet again (that will mean loudspeaker A is now back to where you started). Finally, if you could change the phase of loudspeaker B again - both will then be in phase and as in the beginning. (Does it sound the same as in the beginning?) Note down your experiences and kindly tell us. Meanwhile I will hunt for the circuit diagram and see how the pre/main amps are connected. I do hope you have time for this exercise. Incidentally, you know not to do loudspeaker 're-wiring' while the amplifier is on - some do not like that. Thanks [/QUOTE]
