Speaker Cable Suggestions

My stereo system is Oppo-105D/Emotiva XPA-2/B&W 803s.  I could spend 1000% more and MAYBE achieve a subjective 5% improvement in overall SQ

That pretty much says it all. No bias there what so ever. Congratulations on reaching the top of the mountain. I used to think you had no credibility, now I am sure of it. Nothing wrong with those components per se, but to believe it cannot be improved upon by more than 5 percent by wisely spending a thousand percent more.....what a hoot. IMO they could be bested by spending the same amount, YMMV.

 My opinions are not biased because I have researched the science and believe it.

I hate to break it to you, but your statement is biased. It makes the assumption that science knows all there is to know about the human hearing mechanism. It also assumes that the only measurements that matter are the ones that we have the capability to make now. History is full of examples where this kind of thinking is proven absolutely wrong. The person that thinks they, or science, know everything there is to know about any subject is a fool. 

Do you know other members well enough to call them foolish, delusional, ignorant and all of the other things that you repeatedly call people? Have you personally experienced what they have with their systems in their rooms? When does the shoe you prescribe for others fit on your foot? It doesn't matter if it is directed at one person, or is a general comment thrown out at everyone. Me thinks that you need to develop thicker skin if you are going to go on insulting others. Personally, I take no offense to what you said for the reason you objected to in my last post. I could see where someone as sensitive as you could be offended by your postings. Look in the mirror.

To the OP, if 6 feet is long enough, there is a pair of Audioquest Oak in your price range that would work well. The Silnote cables are nice, but resale is not good if you decide to move on. Another really good cable is the Cerious Technologies Graphene Extreme and are highly recommended. Good luck. 

What you say and how you post is classic trolling. Posting something provocative for the sole purpose of obtaining a reaction. Pretty much the definition to a T. I am sure your tender feeling will require that this post be deleted, but at least you will have seen it. Obviously, self awareness is not a strong suit for you. Buh-bye!

I served almost 10 years in the Navy so there is no need for you to lecture me. You took the thread off target by claiming to be offended. You made it about you by commenting on my post.  If any comment, such as those you routinely make, is directed to the forum in general, (i.e. is nameless), it is somehow not offensive? Really? I gave my opinion. If you don't like it, tough. Move on. Why should I care about your feelings when that same courtesy is not extended to anyone else here by you?  Apparently you did not notice that I did make a couple of recommendations based on the OPs question. Right on target. As long as you keep putting the target on your back, the torpedoes will continue coming. 

Now back to regular programming, I still recommend Oak and the Graphene Extreme speaker cables to the OP. Either would work well for you. 

Cables cannot "change" (for better) the audio program

At least you are right about one thing. However, they can, and all do, take away from the signal that is being sent. That is without exception. The best cables take away the least or inject their own voice the least. The I know science kool aid is so strong that some can’t accept that we don’t know everything or that it is entirely possible that we don’t yet know how to measure everything that matters in respect to human hearing. That kool aid is very strong.
