For the short question skip to the bold part below.
I have an almost new Beosystem 5500 en I have a set of mint Beovox Penta connected to them. I also bought a set of Beolab Penta III just because I needed to have them (The brochures I had under my pillow as a youngster). They were in a less that perfect condition (optically 100%, technically 70%). I stored them upstairs until the guy at B&O told me these speakers were superior to the passive Penta's. So I repaired them to be like new and connected them to my Beosystem 9300 upstairs. Think the guy at B&O was correct. The amps make the speakers superior.
BLong story short: can i connect my active Penta;s to my 5500 amp? I cannot connect them through Powerlink (5500 amp hasn't got the connections) and i fear that the Speakerlink connection won't fully use the built in active amp's of the Penta's. Would a Neosound core solve the problems? Or do I need to look for a fully functioning Beosystem 7000?
