Bi Wiring for speakers question

+1 Hifiman. 
Keep it simple Will. The AQ GO 4 is a reasonably priced cable and should not cost a fortune to do a true biwire. Just try to keep the lengths equal and as short as practically possible. And, add a little wiggle room for minor adjustments. Nothing is more frustrating than having to move a whole cabinet of equipment just to get to some cables.

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.  

@will62 ,
You do know you can get some Banana to spade convertors?
I use these when I have to.

Yep different brand cables work beautifully for me.
