Doug Schroeder Method, Double ic

Keep in mind that an RCA connector does not have a characteristic impendance of 75-ohms. Use a BNC connector if you want a connector with a true 75-ohm characteristic impedance. Problem is that most home audio transport and DAC separates have RCA connectors as their S/PDIF coaxial connection. The Canare RCA connectors are quite good for use in 75-ohm coax cables, but they are not true 75-ohm connectors (see the Bluejeans Cable article).

   My two Teo Ultra's run with the Schroeder Method using Audioquest RCA splitters ($12.95 ea × 4) yielded noticeably better sound than my single RCA Teo Ultra. I loved the Ultra big step up over previous Game Changer. Trying to Remember exactly, but I would say difference in step up similar from 2 Ultra's using Schroeder Method on par with performance gained moving from Game Changer to Ultra RCA IC. 

Tuffy, I am certain the Teo Audio folks have evaluated their current lineup of IC’s in all permutations. It would be insightful to hear their impressions. 

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....
