Doug Schroeder Method, Double ic

Douglas, you mention owners of NOS DACs needing to take caution when employing the SM, why? Are you referring specifically to those DACs which take the output directly from the chip with no buffer?

k4rstar, yes, you will want to speak with the manufacturer in order to see if they are comfortable with the implementation of Schroeder Method. When I was conducting the Border Patrol DAC review Gary Dews was not comfortable with implementing the Schroeder Method with that DAC. Other manufacturers might differ. Someday it may be found that the method is universally benign to other gear, but I'm not at the point of stating it yet. 

@douglas_schroeder Thanks for the reply. Do you know if the popular R2R DACs from Denafrips (Terminator, Venus) are compatible with this method?

My Theta DSPro Basic 3A R2R DAC has no issues with SM IC’s. 

Doug thank you for the clarification, I misread it, thank you for the welcome invitation as well, I know if ever I will visit you and listen to your system , I will learn a lot,
