Ozzy, I have heard the Hidiamond in two systems...both that have previously had HFC CT-1E's. I find the HD's to be excellent cables. Very musical, open and detailed. I have not had the opportunity to hear the Ultimate's, but the Enhanced were also exceptional cables.
My personal experience has success with mixing the two. Nice body, prominent bass, good extension, and no lack of detail. With full HFC loom, the presentation was thin...my system, perhaps. Now, with HD speaker cable, P-4 powercords, D9 ic, and HFC CT-1E ic my system is pleasingly the closest ever to live. I would love to try the Ultimate ic's. Some attractive deals on the 'gon. I am tempted
