Advantages of bi-wire?

Cool. My speakers are AR9's (vintage--they might be older than some of you so that you don't know the speaker. Came out in about 1978 and ran until '81 when I bought mine). I have them biamped now and have never bi-wired anything. I'm thinking about getting the hk990 integrated. I am surprised that that there is not agreement on the superiority of bi-wiring. I thought it was a given. So I've learned soemthing already. Lynne

Depends on the speaker. I have done both single and biwire. In the biwire runs I usually use a smaller gauge wire for the HF. It also depends on the speaker cable and its ability to accurately portray the HF range. If this is the case, I use jumpers.

Boring.

My Maggies come factory ready for bi-wiring/amping.
But, since I'm a poor skeptic, I simply changed out the AWFUL Chrome Plated Steel jumpers for some hand-whittled 6ga copper and feel so much better that is sounds better! The wire was 0.40$/foot.

Like the Home Depot has. There is some critic who swears by speaker cable home made from house wiring that he gets from Home Depot. Can't remember if he uses 8awg or 10awg.
