I use two different PC's connected to WHS 2011 server. My media collection is roughly 35,000 songs. I currently have the LES speakers connected to only one of my PC's with the optical cable. (sounds great BTW) My question is, could I connect my other PC via the 3.5mm jack to the LES speakers without causing any problems? There are times when both PC's are on, but I would never be streaming music on both systems at the same time. What would happen if I did connect to a web site that for instance suddenly started streaming a commercial on the non streaming PC? I want to protect not only the speakers but my PC's too.
