Best "Giant Killer" Value Cables For...

Cullen Cable PCs and Clear Day ICs and speaker cables. Cullen's Gold Series PC's in my system replaced Shunyata Diamondbacks and made them sound like cheap stock cords. And I replaced Morrow sp4 speaker cables with Clear Day Double Shotguns and it was a TKO. And Clear Day ICs bested Audioquest King Cobras in my system by a wide margin. Both of these companies offer money back refunds, and are fabulous to work with. Heck, Paul at Clear Day will probably send you some for trial. Contact him. You will not regret it!

My go-to lower price cable seller is Audio Art. I have one pair of ICs and just bought a power chord from Rob Fritz of Audio Art. Very easy fellow to work with, good sounding cables - very smooth and detailed - well made and they have a good return policy.

I have a lower powered Class D amp and the power cords I've used with them with good results were DH Labs Power Plus power cords and Pangea AC9. For ICs I liked using Morrow Audio 1.1. Speaker wire was real budget. I used White Lighting Moonshine cords (14AWG Patio Cord extension cable from China) Locking Banana plugs on the amp side and bare wire on the speaker side.

Cullen Power Cords are on the wish list (sorry Patrick, I am going to buy your p.c.'s at some point, I promise)
Paul at clear day makes some great cables and is a true gentleman!!
Frank at signal cables makes great cables and is a great guy to work with also! I run silver res. xlr's and speaker cables and love them. They bring out details that were just not there with blue jeans. Blue jeans is better than monster cable (of course) and way better than the audioquest rocket 44's, just not of the same caliber as clear day or signal cable :-)
Also have tried tara labs rsc prime 500. Good creamy mids, but lacked high end sparkle and bass articulation. Almost kept the tara's though. Go figure.

Well, I am happy with my Cabledyne power cords. FWIW.
