In my limited experience, I tend to agree with balanced cables for balanced electronics. Krell states that both components you have are balanced. Nothing to get excited or impatient about. Mortgage or rent, food, beer, and some good CD's come first.
XLR or single ended cables and why?
Few audio equipments reviewers swear by their reputation if there is any that XLR connections improve quality of the sound sonically. Some stated there is none. Can someone scientifically help me to make a wise decision to choose between XLR and singled-ended cables?
