Doug Schroeder Method, Double ic


I think this topic deserves its own thread , where use double ic through y adapters , from source to preamp, Can’t connect it from Preamp to Amp...For me the result is huge, I can’t go back to single ic....

Digital coax connections use 75-ohm cable; digital AES/EBU connections use 110-ohm cable.

In principle, the both of these paralleled assemblies should have lower than optimal characteristic impedance. (To answer your specific question, the dual assemblies should have one-half the characteristic impedance of their single run counterparts.)

In practice, however, both provided better
SQ than a digital cable having the “true” characteristic impedance. I don’t pretend to understand the underlying theory for this result. 
Celander my impression to your response , no risk right, if I will try the rca like you have now, it’s my responsibility to take the risk, like Doug said try it at your own risk.....thank you 
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.
