I read in the sticky that the 3575 will amplify the incoming signal if it's first in the COAX line, i.e., cable-in > 3575 > STB. I currently have the STB first in line, with a composite-in to the 3575, and component-out to the TV. When the 3575 is turned on, and selected as the source (E1), my SD picture quality is better than it is directly from the STB. My question is this: Am I experiencing the same "amplification" phenomenon as if the 3575 were first in line? If so, I'm wondering whether it's worth re-wiring my system, or rather just watching SD channels through the 3575 (turned on, of course)?
In other words, is the only advantage to the "first-in-line" approach that the 3575 doesn't need to be "on"?
