Meanwhile, I've ordered the IR Eye. Can anbody now help me getting the right cable to connect it with the Core? Or can I just take one of my many unused RJ45 cables and somehow follow this diagram? Never cut one yet. Thanks!

Hi Giorgione, nice! You can cut the end of a normal RJ45 patch cable, see also the note to 'extend' the cable. You only need to puzzle the correct wire colors. Good luck, let us know! Regards, Johan

Thanks, Johan. Will keep you updated. I wonder whether I'll be able to hear any difference between the analogue and the analogue-digital setup. Maybe I'll give my hibernated BL9s another chance although I don't think they'll match the BV 120 resp. 150. Digital and processed stuff comes in nice and handy but - as a nearly digital-native and early enthousiast - I've come to the  conclusion that digital vs. analogue is like fast food vs. home cooking. Rather a matter of time/situation than of taste.
