I'm in the process of househunting to include a very large listening room, which will be equipped with a pair of Infinity RS1b's. There's a lot of info and recommendations with regard to suitable amplification. What I have available to me is a pair of NAD 218's for the bass towers, and a pair of Threshold T100 class A power amps for the mid/high arrays. The NAD should have good control of the bass, and I'm thinking the Thresholds may be quite a good match for the mid/highs. I'm planning on running all four bridged, but I can't find any info on bridging the Thresholds nor their output in mono, just that they are 60w/ch in stereo mode. Anyone know anything about this particular amp/speaker combo?
