Hello Beolovers, It's been a long time since I visited the forum. Hope you can help and give me some hints. I have a beovision Avant 55, a pair of beolab 17 and a Beosound Core to play a beogram 7000. When I connect the beolab 17 on the beovision, and want to listen to music (Deezer or Beogram) through the Core using only the beolabs 17 (I created a speaker group on the beovision), I have a really degraded sound quality if I compare to the solution when the beolabs are connected to the Core directly (hope it is clear :-)). It is just problematic since I cannot use the beolabs as front left and right fort the beovision if I want a good sound quality with music. Do you have any ideas to fix the problem or do you encounter the same situation ? It seems the sound treatment of the Beovision affect the sound quality. Thanks for your help, have a nice listening evening on yours systems Eric
