I recently bought a refurbished Marantz 8200 that arrived DOA. Now that I have my system apart and the backs of all my components are accessible, I have considered doing a comparison of the speaker wires in my house using my old Yamaha. I have a radio shack 12 gage wire($30), Monster Cable ($95), and Mapleshade Helix speaker cables ($85, on the way as I type this). Because of the time involved to take both wires off and put new ones on I figure that it could be difficult to pick up differences in the wires/cables. It will take more time because only the Monster wires have banana clips. What I was thinking of doing was connecting two wires at a time. One wire would go to the left channel on speaker set "A" and the other would go to the left channel on speaker set "B". I would then put the receivers output to the "left" speaker only and switch between "A" and "B". This would not be a stereo comparison, but I think it may be a fair comparison because both wires and speakers will be playing the same information. I would think that it would be easier to pick up a sound difference between 2 different speaker cables playing the same channel than comparing the left vs. the right channel when the information/sound would be different. Does anyone agree or disagree with this method. I plan to do it regardless, but would like to hear input.
