Help Bi-amping question

My system consist of a Classe model 25 amp, DR5 Preamp, Rega Planet cd player and B&W matrix 802's series 2. I recentley bought a pair of Classe DR3's as Ive never ran pure class A before. I also have never bi-amped before. How do I set these amps up in my system. Ive been using Audioquest Crystle Hyperlintz bi-wire with the model 25. To Bi-amp the two DR3's do I need to purchase another run of bi-wire? Do I need any other interconnect. I'd like to get these amps up and running fast so I can make a comparison between the DR3's and the model 25. I'm very happy with my system but got the upgrade bug. Problem is I'm alot better at listening to music then I am a the technical aspect. Appreciate any advise that can be given. Cheers Gary

I have a pair of Classe 25 amps and Martin Logan Ascents, I too tried the amps in mono and all you need is one pair IC and two pairs speaker wire if you bi-wire the speakers, I also tried them bi-amped vertical and they sound better this way, you will need two pairs speaker wire, two pairs IC and if your preamp only has one set of outputs you will need some Y adapters or if you have a set of balance outs you can pick up come RCA/XLR adapters from cardas or audioparts.com for around $40 or Monster makes ok ones at $20. I found the bi-amp vertical to be much better than running the Classe in mono, when running in mono I got a slight hiss from my speakers and over all sound was not as musical as even using one stereo amp but when I bi-amped the system became much more musical over both mono and a single stereo amp. You may want to try the DR-3 on the panels and the 25 on the woofers and then swap them around, could be fun!
Happy istening!
