You know when you are dealing with a BS company....

Too funny! 15% of what? :-)

I have Morrow speaker and interconnects and have used same for years. I find them to be well made and they perform superb in my system. I recommended them to a friend who just got new B&W speakers and a McIntosh amp. He has always been a cable doubter and he was really surprised at the difference. He bought the middle of the line speaker cables.

What I can say is that I switched out my FMS Black speaker cable for Morrow SP6 and my Kimber PBJ and Mogami interconnects for Morrow MA4s and three seasoned audiophiles heard a significant positive difference. We also did comparisons between older mid-range MIT interconnects, Morrows MA5s, and PBJ. The Morrow interconnects were on par with MIT and both were better than the PBJ.

I did also talk to research scientist who has oversight on building satellites for the DoD and while I can't begin to recount his explanation, he did infer that there is research that dates back about 2 decades ago that supports the Morrow design philosophy.

Are there better cables? Sure, but I'm satisfied with the improvements I heard when I switched to Morrow.

OP 👀 da fool. 

It is apparent from the comments on this thread that Morrow is considered to be legitimate and offers products that are embraced by many in this group. The challenge from their perspective is how best to communicate the value of something subjective in exchange for something tangible -- your money. The long term proposition is to send you product and you send them money. Then, if their products meet or exceed your expectations you’ll buy more of it, and give positive referrals to those you know. Delivering the "right message" is not an easy task, especially in a crowded arena or introducing an immature product segment. We’re terribly deficient at attaching objectivity to product performance via measurements. We also know that superlatives can set off alarm bells when claims cannot be substantiated: "The only way the sound could be improved is to have a digital bitstream plugged directly into your brain". So, Morrow attempts to connect some metric to their assending product price points via some "reasonable" number that represents a degree of performance improvement. So, you spend xx% more and you’ll get back xx+1% more in audio performance. With return privileges, if their numeric assessment of improvement did not align with yours.

Marketing geniuses they’re not. But, with some success and a little luck, they may tweak their messaging to be more in tune with your reality. And, allow the product to do most of the talking.
