Hello there, I am new here and I apologize if this is the incorrect place to post this question. I currently have a Sony STR-DH 750 AV Receiver with Polk Blackstone TL250 speakers on a 5.1 setup. (My very first system) I would like to upgrade my system completely and I am debating between upgrading my speakers first or upgrading my AV Receiver. I’d like to purchase Klipsch RP 260F speakers with a 440 Center. Will my AV Receiver be able to power these speakers along with my current 2 surrounds or will I damage the speakers? Should I buy the AV Receiver first? The AV Receiver I have in mind is the Denon X4400h.
