@Dieago I am sympathetic to you but while I agree Danny at GR does seem to really know about Speakers and Cross Overs (although I'm not 100% sold on what he builds until I see some independent testing and reviews), he's definitely drank the wrong Kool-Aid on Cables. (I'm also not sold on Tube Connectors either.)
I have a very wealthy friend who spent over $10,000 on MIT Cables with Boxes on them (see
AR Mono Block Amplifiers...and Speaker wires ) for his stereo system - not a Home Theater (His two Wilson X-1/Grand SLAMM speakers were over $100,000 - all prices in CAN $). He was sold on the MIT Cables by his dealer, but eventually after multiple unexplained failures of his AR Monoblock Amplifiers (costing thousands, and months of time to ship them back to & from the Factory to repair each time), I convinced him the Boxes on his MIT speaker cables and interconnects could have failed causing his problems. I changed the interconnects out for World's Best Cables (OMG I hate that name!) which are very well built for less than $500, but technically Monoprice, or Blue Jean, cables would have been fine. It's been over 2 months and so far, no issues.
I really hope you enjoy what you bought, and the memories of visiting GR. Some here would really have to swallow hard (like a 40 pounder of Crown Royal) to believe everything Danny says. Sorry.
