I have an AudioSource Amp One/A, which i received for a gift so i could power my passive Subwoofer. Sentimental value aside, i have found no use or value for this. I see on places like Amazon and other online stores when doing a google search, that it's worth like $199+ Since i now have a powered Subwoofer, and i dont use my old one, it has just been sitting with no use. I was looking through the Home Theaters people have set up on this site, and seeing how they have an Amp themselves, but they dont explain what they do with it. My question is: What can i use this for? In the back of it, is 2 speaker wire inputs, one for the left and one for the right channels. In the front you can control the left and the right. Also in the back are RCA inputs for Line In and Line Out. How would i use this for driving extra power to my floor standing speakers? Is there a way i can hook it up to my Sony STR-DE895 receiver to give power to that? Ive been contemplating on whether or not i should keep it or try to sell it, but im not sure if i can get what its value is in return. Thanks for any input.
