Full E.A.R. + Spendor SP100R: cabling ?

I use Spendor S 100s internally rewired with Cardas [ except for tweeter , which is silver] driven by a CJ Primer 350. I have Cardas Golden Reference speaker cables [bought used]. I have been using VDH The First since the early 90s, now using the latest version. I was a dealer back then and became one again a year ago. I used then in the 14 years when I was out of audio retailing. While there are marginally better ICs like the top Cardas and Transparent they are FAR higher in cost. I saw a pair of First Ultimate on here for $220, you could try a pair and resell it at little if any loss if it didn't suit you.
