Hi everyone. I have given my B&W 601 s2 speakers to my brother. I had them biwired but he has to use them single wired. I dont have the brass plates they came with. He has just used bare wire QED silver anniversary cable and put a big length of wire right through the binding posts to connect the lf and hf terminals. Is this an ok way to connect them? He says they sound good. Thanks in advance for any help on this.
