@2007audioman - all of the IC's were good quality - Van den Hul DL102 mkIII with Furutech RCA's
and wired in a floating shield configuration.

I replaced the Surround IC's with DH Labs Silver Sonic with the same Furutech RCA's and found there was no discernible difference
Perhaps the IC's were not of the same caliber as the Audioquest models you listed, but I could not hear any downside by using the DH Labs
Hope that helps
