Balanced/Unbalanced --- Whats the difference?

Ok I found the search, sorry for that guys.

Papi, as for your last question and using your example. If the integrated has balanced inputs only and the CDP only has single ended (RCA) you can use adapters to make the connections. This works, however there is a slight degredation in the sound. It is always better if you can avoid adapters. Also, not all components that have balanced connectors have the balanced circuitry inside. Just something else to watch for. Look for statements in the ads like "fully balanced" and such. If you don't find it in the literature, ask. As for BAT, I know their equipment is fully balanced and there are many other brands that are as well.

I know I will pay dearly for this but when I hook-up the Krell 280 CDP to my 400XI with Hero RCA ICs, tremendous amount of bass and warm sounding. As opposite, with Hero XLR I get more details and less "big bass", very balanced sounding. This is just my own experience with my own gears. I understand others will think otherwise.

Why will you pay dearly? It sounds better to your ears right? Don't over analyze and GAS what others think; accept it and enjoy the music.
