I haven't been able to find the answer to this: With the preamp-out/amp-in slide switches set to "connected," are the RCA preamp outs still active? I want to run an separate headphone amp while using the B135 volume control. Any downside to this setup (for instance, voltage-drop with two sets of outputs connected)?
Assuming the outputs stay active, would there be any difference (electrically / sound quality) between this B135 setup and using a set of the RCA preamp outs on a BP17?
I assume that all three preamp outs on the BP17 stay active all the time? I didn't see anything in the manual about switching outputs.
In my proposed setup, the amp for the speakers would be switched off during headphone listening.
