I just got rid of some very old BOSE SE-5's picked up a set of POLK R30's and was so impressed with the diffrence in sound quality decided to upgrade again to the ATHENA line based on reviews and price. Am I likely to notice a dramatic diffrence in the new system? I will be replacing a BOSE Center, POLK S-10 and the POLK R30's. Still thinking about picking up the ATHENA rears. BTW, I'm running a JVC 8010 Reciever.
