I am running a 7.0.2 speaker setup in the moment, with BL50 wired as front speaker, left/right back (BL3) and left/right surround high (BL4) with WISA. the left and right sourround (BL3) wired with a B&O RJ45 splitter with one Cat7 cable from the Harmony. So how is the best way to connect the back speaker with cables? Cable lentgth is quite long, unfortunately no short cut to take, roughly 15m for one side, 20m for the other. The Harmony has four PL sockets, one is for the BL50, one for the back hight (BL4), one for back (BL3), one for the upcoming front high (BL4). the left/right surround need to run WISA. So I need to use a splitter as all socket are taken First idea is to use two Cat7 cable to , than the B&o RJ45 splitter, than RJ45 to DIN Powerlink cable. Or as alternative, go for the long distance with a Rj45 to Powerlink DIN, use a Y cable with DIN Powerlink. What is the better option as a heard mixed views on the RJ45 splitter?
