Best "Giant Killer" Value Cables For...


I realize there may be other threads on this topic, which I haven't located yet - but, if someone can direct me to them, I would appreciate any help you can offer.

Or... in the alternative... please let me know your thoughts / experiences with the Best "Giant Killer" Value Cables to connect to a Class D Audio amp, and class d powered sub.

Looking for RCA interconnects, Speaker cables and power cable. I'm one who believes you reach "diminishing returns" very quickly with cables - so, I'm unwilling to spend a King's Ransom on cables.

That's why I'm considering Blue Jeans Cable, Better Cables, Signal Cable, maybe some others in that context.

Thanks for any help you can offer.

I'm not sure how they do with Class D, but in my system Level 2 Performance Series Bi-Wire Anti-Cables performed equally* to Audioquest Sky. $2,500 a meter or $46 a meter? You choose.

*Caveat: the Anti-Cables need to be reenergized for 30-45 minutes after any week long vacation. The Sky doesn't.
This is somewhat of a "late entry". Almost didn't bother. WHY??? Because you can talk to 50 different people and get 50 different opinions, the majority of which may not even be relevant.

I did notice (above), two or three entries pertaining to REALITY CABLES.
I have known Greg Straley for a number of years now, since he started his boutique cable business. At that time, he was either President or Vice President of the "CHICAGO AUDIO ENGINEERING SOCIETY".
Resultantly, he had an entire panel of "extreme" audio enthusiasts and engineers at his disposal, that provided significant assistance in his product R and D. 
The first time he got me to try them I thought, "are you kidding". These things look like red rattlesnakes, which I have fondly called them ever since.
At that time, he left a set of IC's and speaker cables with me to evaluate for many months. During that period, I went through a number of pieces of tech Including PRIMA LUNA, and AYON. Also, MUSICAL FIDELITY, plus a couple of other custom pieces. At that point in time I had already accumulated about 30 different brands of cables, including ANTICABLES, MORROW, and HARMONIC TECHNOLOGY, to name a few.
So, what's my point here; - - - With all of my component swapping during that period, I have to state that in every case, and components combinations I put together, it was always the  REALITY CABLES that shone the most brightly in the audio reproduction path.
To this day, and many pieces of tech later, I am still an avid fan of REALITY CABLES. GRES STRALEY has made several upgrades to his designs since the time I bought mine. One of these days I intend to try his latest offerings, though truthfully I don't know how they could be improved significantly over my old and current ones. 
Well, perhaps making them more flexible, but that just doesn't fit the design equation unfortunately.
