Cords are funny like that, they are very dependent of the equipment they are attached to. As much as I like the Elrod cords, I have found that they never worked well on anything designed by Dennis Had (Cary/Inspire). Of course someone else may disagree, that is the nature of the beast. Like you said, you have had success with the HiDiamond cords, just not on your amplifier. I am totally unfamiliar with your amplifier, so I cannot even say how the Elrods would perform with it.
Another cord that I would recommend looking for, though it may cost a bit more than $500, is a PAD Dominus w/ Ferox. I actually preferred the older Dominus cords to the newer 20th Anniversary/ Canorus cords.
