as most here already know polk SDA speakers require a "common ground" amp. They say that MOST are common ground amps but some how I just seem to know how to pick them. Seems to me this site needs a data base of common ground and non common ground amps and receivers to make this a bit less painfull for those with newly aquired SDA speakers...
please cut copy and paste the running list and add to it. please don't post until you are sure.
non - common ground amps - don't use with your SDA's
