addition of 2nd pair of speakers


I own a Linn Magik component system. I'd like to add a 2nd pr of speakers which my amp can't accomodate. Can anyone recommend a good, quality speaker selector box I can purchase to accomplish this, as I am concerned about having it provide the proper power protection especially when playing both prs. simultaneously.

I bought an Acoustic Research AR1108 at a pawn shop to switch between two sets of tower speakers. It worked perfectly. It has built in protection circuitry. I ran it off my B&K 200w amp. I did not hear any audio degradation at all.

Adcom also makes a speaker selector switch. Does anyone know how it compares to the Bryston?
