I'm probably a bit more skeptical than you on his cable and parts claims, but I am open minded enough to look at an independent technical review of his work.

@Pandaman617 had his SVS Ultra Center "upgraded by Danny. He said in an earlier post" I’ve got the REW graphs and pics of the SVS before and after somewhere and if I can find them I’ll upload them." Hopefully he'll do it soon, but you can see the Danny's video on it starting at 6:05 here:
SVS Ultra Center YouTube
He posts his graphs (before and after) at about 9:11.
Gene, I have an idea, if Pandaman617 would send you his modified SVS Ultra Center for review, would you do it and post the results here? Of course it would be great to compare the new results to the data sent (before and after) that Danny sent to Pandaman617. I don't remember it Audioholics already did a review on SVS Ultra Center, but I'm thinking it has been done.
Sounds like great content for the Site, and perhaps a monster YouTube video too!
