Speaker cable suggestions for B&W 800 Diamond

I did a lot of consulting. I visit a lot of people with expensive sets. But I never had a client with the need of 20m of cable. Wenn you spend this kind of money on speakers you need to spend a lot of money on amps and cables to get a good level in quality from your 800D. I had clients who got about 30% (quality) out of there expensive speakers. Because they did not have amps and cables which match the capability of there speakers. I could not blame them, because they did not know it.

A set of ordinary 12 gauge paired up in a quad twist is going to give you as good a sound as spending $50,000 on speaker cables...
At 20 meters it would be folly to buy $100+ a foot speaker cable.
Naturally folks who think cables are really really important, and who own stock in cable companies will say i am wrong.

Upper level AudioQuest or Transparent.

@ Elizabeth, Hi, I am dumbfounded as to why you would make a claim such as the one you posted on 6-4-13, I know every one has an opinion, The realality is that in my experience I have never heard a speaker cable better than the Taralabs omega gold speaker cable!,$24,000.00 8ft retail, you may research this cable and find that it hardly ever see it for sell on the used market!,I have talked to alot of users of this cable, they may sell most of their Taralabs i/cs, however, they always keep the omega speaker cables for many reasons!, Then when you go into the audiogon circles of the threads, you will find that this cable is also in the conversation as Best available!, At the end of the day, I agree with the reviewers, users,The absolute sound 2012 editors choice of the year 1st place, etc...,such over whelming proof here, I bought my own pair!, I have no regrets and enjoy a realism that no 12 gauge paired up in a quad twist of speaker cables will ever give toward my enjoyment!, Happy listening!

Yeah I am certain a $24,000 speaker cable can fix up the sound a bit.
But maybe spending the $24,000 on the equipmnet would have doneway more, And then using that cheap pair of quad twist 12 gauge speaker wire would have still left the ssetup sounding better than skipping $24,000 on the equipment and blowing it on a stupid cable.
Just MY two cents on the topic.
Your opinion may vary.
