I double checked. Eventhought ARC's website describes the "preouts" to be a subsonic or multiroom output, I surmise it is a full range pre-out, thus the CA-50 can be used as a preamp as well. First of all, it makes no sense that the CA50 can be used to operate in multiroom situation if the output isn't full range. Second, I check Audioreview, for the 5th time, and one reviewer stated the CA50 is close to his LS15 when used as a preamp. Doesn't that give your shivers down your spine? Ok it's just me.
Nothing exceeds excess because excess already exceeds excess so excess can't logically exceed itself. = D
I am one person to choose my stereo over my girlfriend, so I don't place a nice system in my bedroom incase my girlfriend gets jealous. I hope you don't have the same problem = D
You take care too!
