Tuffy , Iam a Teo Cables fan , I do like their cables a lot, My system consist of Andra Eggleston , monoblock musical fidelity, art audio preamp, schiit Gumby Dac , marantz ah toeb transport, when I tried the GC and ultra combo, it took a while before I realise it was too slow, the speed and articulation wasn’t there. Until Davidten visited , He made a comment that my system is more alive when I switch to vynil, that confirmed my suspicion regarding speed, the moment I put the ultra alone. Music came alive Speed is back. Double IC doesn’t always work.i myself Wish the ultra And GC work....
