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.

Bi-wiring is absolutely not necessary. Whether it's beneficial or not is a separate question. You'll likely get differing opinions on that, so you'll have to decide for yourself.

I ran Response 2.5's both ways, and didn't notice any real difference.  Just be sure to replace the metal jumper bars with some quality jumper leads.  The same brand/model as the speaker wire is of course ideal.

All other things being equal, I think it's more cost-effective to put the $$ you would spend on two runs of wire towards a better grade of single run.

Of course, there are speakers that more or less demand bi-wiring; this isn't one of them.

I have had a number of Proac speakers and found that I was better off with a higher quality single run and high quality jumpers.

My system is posted here if you want to look at it.

Completely with you on this! ProAcs need some good quality wires and jumpers.

Reach out to a good dealer and/or cable maker and see if they can make a nice pair of jumpers for you.

This is a well-travelled off-repeating question dissected in AGON and just about every other audio forum.

Here is one on AGON worthy of prior research that is readily available in your journey

https://forum.audiogon.com/discussions/bi-wire-or-not-to-bi-wire

In brief:

(1) It is always system dependent as best evidence ,

(2) Without prejudice of the above, an increasing number of major manufacturers are advocating a best-of-breed single run and jumpers array.

CHORD even stopped making dedicated bi-wires.

Bi Wire: another urban joke. If you would use a single wire of x guage, instead of a bi-wire that has the same guage (each has half) the single would do better.
It can be analyzed on "Spice" as well explained in simple words. 
Bi wire was a trend of the 90's. No more.

Thanks to all for your insights...appreciate the community spirit.  

As an quick exercise, I checked out Kimber Kable 8TC single run with 8TC jumpers v. 8TC bi-wire.  An 8 ft run of the single 8TC was $493 (pair) and the jumpers $160 for a total of $653.  The 8TC bi-wire was $558.  Go figure.

Some makes/models just use the same number of wires/strands inside the cable, and wire them differently.  So with those, on the bi-wire model, half the number of strands is being used to transmit treble and half for the bass.  I don't know whether this is the case with the Kimber, but the similarity in price certainly suggests it.

I bi-wire my Klipsch Heresy IIIs with AQ Rockets as I was using them for my previous speakers and am too lazy to put my single wire cables back in. I suppose I can stick the jumpers on to replicate the single wire experience, but the sound is currently so good I just don't wanna.
