You will be disappointed with my answer because even if you bought HFC's Ultimate Reference Helix Power Conditioner at $24,900 and connected it to the wall with the Pro version of their mains cable at $20,900, you will still notice further improvement by plugging in one MC-6 into the wall. At AXPONA in Chicago and again at THE Show in Newport, Rick Schultz had this exact setup and as he plugged in more and more MC-0.5s, it was clear to everyone in the room that there was improvement each time. At one point, he had more than 40 of these MC-0.5s plugged in and there was improvement with each one. Others here have suggested there must be some gimmick at play, that this is all marketing hype but in my own setup, I have indeed found this to be true, that the more magnets the better. Where is the saturation point where no further magnets make a difference? I'm not sure but I have not yet gotten to the point where I am finding the law of diminishing returns come into play. With each piece that I have added, I am just surprised by the advancement that it brings and my decision to finally slow down has more to do with economic reasons than anything else. As I have suggested in several posts, I would probably run out of money well before finding the point of saturation. Is this stuff for everyone? I don't know. It can get outrageously expensive and so many will dismiss it based on cost alone but whatever this magnetic conduction technology is doing, I have not heard anything else do what it does and it speaks to my sensibilities in exactly the same way that the DAVE does. I have been in this hobby long enough that very few things impress me all that much anymore. As fellow DAVE owners, I suspect this applies to many of you as well and yet the stark realism that I now experience from my system every time I turn it on never fails to impress. I believe there are others here who are beginning to experience some of the things I am experiencing and so I will leave it at that.
