I am new to the Community and am excited because my new Klipsch speakers just arrived. It was hard to hide them from my wife. I have an Onkyo Tx-r2820 receiver. I tried to research what gauge speaker wires to purchase but I am now thorough confused. My plan was to use the new speakers in addition to the Bose Acoustimas 6 series which I already had. Can someone familiar with the receiver and speakers advise on what might be good options?
