Grover Huffman Speaker Cables

here's an email I recently received regarding my speaker cables

" Floored by these speaker cables. I had no idea that speaker cables would have such a strong influence on the sound. I assumed the SUT to pre would be the biggest change, but I’m not sure.
Maybe old speaker cables (audioquest Aspen) just sucked?!
Anyway, you are a talent. And I’m grateful.

Come on b4icu let's compete what are your cables? Let's listen to them. 

Ask Grover that dude is very smart.

“”””Groverh, please share your answer to the original question if possible. Thanks””””
I just bought a pair of 6ft SX cables to and compared them to what I previously had in the system 1.5ft CARDAS Cross/SPK Bi-Wire. 
In my system the SE sound better than the Cardas. The build quality is great and the price is very accessible for a high end cable. 

As I respect b4icu opinion on the calculation I do not respect the comment on the builder not knowing what he is doing. I just find it ignorant. 

I just ordered a full loom of Grover's cables.  He feels pretty strongly that he makes a good product since he'll take them back with no questions asked for a full refund.  In that case the only opinion that matters is mine.

BTW I believe power cables are snake oil.  Grover shipped me a Pharaoh version of his and I plugged it into my Don Sachs preamp.  The impact was immediate and completely recognizable.  I was prepared to ship it right back to him but I think it's a keeper.
