I made some interconnects and speaker cables from high quality but affordable stuff. Good quality microphone cable and good ends for interconnects and industrial 4 conductor 10awg cable with fine stranded copper for speaker cable. I put spade and pin connectors on the speaker cable.
Even though bi-wiring doesnt make any difference - at least to me in theory shouldnt. I did it because so many were telling me to try it.
Not sure whats changed but basically everything sounds 'bigger'. Just sounds like all the walls in the room got pushed back like 10 feet. I was shocked actually. I was sure I should get no change in sound. I mean wire is wire right... or at least to a point.
Update*** In the past couple months, after doing some cable testing and blind listening tests involving swapping of cabling, I can pretty much say that I had a very hard time telling anything apart. After wondering, why I initially heard huge differences, I did some research and came up with a really good article from a famous speaker manufacturer.
...check out something called "cable Nonsense" which should come up if you google it. Its by Dunlavy Audio. Very interesting read. Also a great video called "audio myths workshop"
Basically ends up that most audible differences in cabling and such are in the mind because one expects to hear a difference and therefore does. Blind listening is the only way to tell if there is a difference or even better, a good ABX test. As long as the cabling is good enough to meet certain criteria, then audible differences should be pretty much nil. Well at least I didnt spend a lot doing the cables :)
