Thanks Alan, I knew that the sound of the 100's is supposed to be similar, but the main reason I really would like to "upgrade" to the paradigm's if i can get them cheap is because of their cabinet's, my only gripe about the 80's is the cabinet's tendency to have some vibrations which, im no expert on sound but when i stand next to them it seems like i can hear quite a bit of coloration coming off the cabinets. Hence wanting to get the 100's with their higher weight, and more bracing.
Plus, the logo on the tweeters that says Axiom Hometheaters is totally wrong in a 2 channel system.
But either way, I'll either end up an axiomite once again with a shiney set of HG cherry's or the use of my parent's 7.1 kickass system
