Ok, incoming stupid question...what IS a preamp?? I have a turntable 
attached to a stereo system...is the stereo system like a preamp? In 
otherwords, you wouldn't want to attach this to JUST a phonograph - 
using it like speakers, you would want to connect it to the setup 
with speakers, etc.? Or am I not understanding?

Thanks for clarifying...I appreciate it as I am going to be doing this soon!
