Do Audiophile Cables Matter? Here's PROOF!

Grover Huffman turned exclusively to cable manufacturing after a career in photography.  He found manufacturing electronics and speakers too time consuming/expensive relatively speaking to cable manufacturing.  He's been cable manufacturing since 2000.

My experience back in the early 80s was upgrading from zip cord to AudioSource speaker cable with braided flat small multi-conductor wiring.  It was revelatory. 
Steakster -  MasterBuilt Ultra is based on exotic formulation and assembly techniques developed for information transmission systems by aerospace engineers. Numerous high profile organizations, both government and private, utilize this design for mission critical applications.  MasterBuilt Audio is the only company licensed to utilize this technology for commercial audio use.   
I have been a cable beta tester for a boutique manufacturer for over 2 decades.   His speaker wire has only undergone about 4 or 5 changes in that time while his IC cables required at least 200 designs to get to his Empress and Pharoah line.   I don't know if they would pass noise or filter highs.  I just know that music is unaffected by the cable.  They are patented air core insulated design without braiding and without individual conductor shielding.   The design blocks noise though.  See http://www.groverhuffman.com/   I haven't compared them to MasterBuilt, but the price difference is about 50X less expensive.   We have compared them to many high end cables costing 3X to 20X more expensive.   His Pharoahs are neutral sounding, without compression, without attenuation of any frequencies and extremely open sounding.
