Hi Mike-
i have owned the signal power cord and no longer use it.If you like the VHAudio cords and can afford it at this time you owe it to yourself to take a listen to the Flavor 4 with gold wattgates.I currently am running four of them with my system and it isn't even close for me in my system what they have done sonicly.He has the 60 day return policy so you have nothing to lose.Truly a remarkable discovery for me as i am rather new to this hobby.I will try the Airsine probably at some time but that is more then double the price of the Flavor 4.I know the Flavor 4 is alot more then the Signal magic but it was well worth it to me and i concider them components in my system and well worth the price i have paid.Hey they are always sought after used as well if you keep them after the 60 days.Definitey make sure you get the gold connectors as i have the one without the gold and was not nearly as good in my main system and is now delegated to my computer studio.Sounds great there by the way : )
good luck,
Craig
