I recently acquired a Beosound Overture 2300 unit, but it came without the Beolab speakers. The previous owner had intended to use it with headphones only (!), and my question is: Can the powerlink connector be used with any set of active loudspeakers? How to go about it? I have a number of out-of-date B&O amps and receivers, but this is my first system intended for active speakers, so I am a complete newbie in this situation. Any help?
