Bi Wiring for speakers question


I've done some research on bi wiring speakers and have noted that some people are apparently using a speaker cable with 4 banana connectors on one end but only 2 on the other end.  I'm guessing that the side with 2 banana's is connected to the Amp or Receiver and the side with 4 to the speakers.

Anyone tried this and does it work as well as using 4 connectors on each side?  Seems to me that using all four speaker outputs on the amp is the right way to do it but if it will work with just one pair of speaker outputs then who am I to judge?

gdnrbob.  Yes, I've already bi wired them to my system when I had the Castle Conway 3's paired to the Denon 520 amp.  But since both ends of the wires are Banana's I have to get new cables to match up the Denon with the Mirage OM 10's which only take Pins since the Spades never fit.  And the Yamaha A500 which also takes Pins but not Banana's will be matched to the Castle's with a new pair with Pins and Banana's.

Just bought a single pair of the BJC Belden 5000 cable to see how that sounds.  Will buy a second set to Bi Wire if they sound good.  Will likely get AQ again for the next set for the other system.
hifiman.  Thanks.  Yeah, I don't understand that advice either.  Will stick with the tried and true method of using the same kind of cable.  
Well, my BJC Belden 5000 10 gauge just came out of the box.  Disappointed.  Have found a broken pin and worse, the connector on one cable for the speaker side, which is supported to have a Banana plug on it is something different.  Won't fit.  The other cable is fine but clearly this other cable didn't pass QC yet somehow managed to find its way to me.  Will have to send it back and hope the replacement is correct.
