Doug Schroeder Method, Double ic

divertitit, it worked extremely well for me when using a DAC with the Redgum Audio Articulata Integrated Amplifier (reviewed for Dagogo.com). Please note that at this time it is still considered a "do at your own risk activity, and if you have concerns you should discuss with your component makers. 

jayctoy, I do not wish to be rude, but I must clarify; I was not opening up my shootout to the public. I was soliciting interested manufacturers who may want to participate in such a comparison. However, I do know you personally, and you are welcome to visit at some time in the future.  :)

Indeed! I referenced “we” in the editorial sense as meaning “YOU, DS.”  Lol

DS: I pm’ed you. 

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.
