A/B test of interconnects - Will this work???

Actually it is all of the above; and also any other method posted later. I do more than one thing, to be sure of my results and final opinion.

I've always done it the way Hotrod recommends. I try to avoid any variable the something like a Y adapter might introduce. I also think I get a better feel for each cable when absorbing a long listening session with each component change as opposed to jumping back and forth. Not that I ignore the fine details, I'm just more interested in the overall experience each cable portrays.

Hey, what ever method you use ,I hope you post your results and conclusions. Thanks!!!

cables are very system dependant

I tend to want to listen to a cable exactly how it will go in my system and for at least several hours or more likely several days to get a truer flavor (tube warm up is always a factor).

I like to keep going back to tried and true recordings that I am very familiar with. I'll listen to pieces specifically and make mental notes.

Looking for great imaging,accurate tonal balance etc. Piano and acoustic guitar are great for getting a true sense of this.

Sometimes a stunning cables gives you a wow, "never heard that before" or gives such detail and seperation of instruments layering. Also musical decay and the the emotional musicality of music is important, if the cable is dynamic and full bodied, you'll be enraptured in the music.

happy hunting
