Bi-Wire Advice for ProAc Response D2

Greetings from a new Audiogoner.  Recently acquired a pair of ProAc Response D2 via an Audiogon member.  Am thinking about bi-wire for these and am interested in any recommendations the community may have.  I currently have a Cambridge Audio 651A integrated amp (until I upgrade of course).

I'm thinking that Kimber Kable 8TC might be a candidate but I wanted to tap into the experience of this forum, even to hear whether you think bi-wiring is necessary.

Thanks in advance for considering.
