Hello to all, I am quite surprised that it is so hard to find a piece of information about this question: When a TT has pre amp or phono stage built in then it can be connected to an amp with phono inputs etc. But what if both , a TT and an AMP have built in phono stage ? Do one need to connect a TT just to other line in like AUX ? Or connect TT with buil in phono amp to phono input ( with built in pre amp ) on amp ? But that seems to double DB and sensivity ? Or simply the phono pre amp on TT can be then switched off ? Thanks.
