Happy New Year! Thanks for all of your replies. To clarify my concern, I am unsure if the HK AVR 630 accepted bare wire speaker connections. I have always run my Klipsch on a standard 2 channel receiver using bare wire for the speaker connections. I did not know if this connection method is obsolete. The connection post on my Klipsch KG 3.5 has a hole for the speaker wire. There is a hollow cap that tightens over the threaded posts. Thanks for any suggestions or recommendations.
