RE: ALT. 1.

"which sounds better, one with 270 Ohms series resistances or 19 Ohms, a 14 fold difference"

But you are presenting an incomplete picture here, by only including the DC resistances of the chokes. If you want to add up the DC resistances in that circuit, then you certainly need to add in the DC resistance of the secondary winding of the power transformer. And the rectifier is in the circuit too.

In your preferred PS, for example, any current that flows through L1 must necessarily also flow through the power transformer secondary and also through the rectifier. So just adding together the DC resistances of the two chokes is simply wrong.
