A circuit is designed either balanced or unbalanced but most can accomodate the other. A circuit will always sound the best running it the way it was designed...that is a balanced design will work best balanced, and a single ended design will work best single ended. It is best also to use the same configuration throughout - that is balanced turntable (xlr connections)and/or cd player to balanced preamp, to balanced amp.
Balanced Cables
Been in this hobby for approx. 3 years now and have always used RCA interconnects. However, I just purchased an ARC LS15 preamp which also has balanced input/output connectors. I am probably wrong but I don't recall seeing balanced cables for sale on the Gon. I need some education on these cables...and where is the best place to purchase these cables ? Thx
