Jeff,
There are definite advantages to ensure the lowest impedance possible in your secondaries. I like Power trannys with multiple secondary windings that enable you to parallel to reduce impedance. This assumes that you can parallel and still accommodate secondary voltage and current requirements. I like to spec my chokes out with at least twice the current capability required to ensure a low DCR power supply....
I have heard the sonic advantages of lowest possible PS impedance but I still accommodate critical inductance so I'm typically seeing around 50 to 60 DCR in my chokes.
I assume that when you use these low DCR chokes, you are not working with a choke input supply. How much capacitance you using? You are limited on the first cap by the rectifier requirements.
Keep building...have fun
