However, you will find out that you don't have independant level control, so unless all the speaker pairs are the same the level will change as you go from one to the next. You will also find that the Niles devices present a different source impedance to the speaker depending on how many you have selected. This will change the low end response somewhat. But the Niles boxes have series resistances in them that get switched in and out of circuit to make sure your amplifier never has too low a load impedance on it. It's not very elegant but it works okay at reasonable power levels. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."
