Hi All, this is my first post in the forum and im glad to join the Klipsch community. Currently, i am using 2 sets of floor standing (RF-82 ii's and Synergy F-30's) as my front speakers. powered with Emotiva XPA2 and XPA3 and the processor is Marantz SR7010. i have tow questions and i need your suggestion. 1) do you suggest to have 2 sets of front speakers ? 2) i am thinking to upgrade my F-30 with RP-280F components? do you think it is good idea ? please advise.
