But even then, I still run them in mono for a tower setup. The Syn-4/DX4, SD-4 and SD-6 can be setup to run a pair of tower speakers in stereo, but again, I prefer to run them mono. Not many The SD-6 will also allow for bridged mono or stereo. Not many amps out there that will let you do with a pair of tower setups like these high end amp. Theres WAY more to it than just wattage.
At best, an amp like the PPi900.4, polk 4000.4, exile xm15.4 and xm30.2, Wet Sounds HT4, kicker KXM400.4 and KXM400.2 will let you run stereo, and thats if you bridge and configure the RCAs properly on the 4 chnls.
Theres nothing wrong with stereo on a tower setup, but as been noted, when off axis, like surfing, you are getting most of your music from that one speaker thats closest to you. In a stereo setup, you are missing some content. Mono lets you get it all. A high end that runs mono properly, can make a tower setup just that much better sounding.
