Yes Bdp24 that goes for everything active or passive from the source output to the poweramp input.
If impedances matching is not correct (Ohms Laws) and the current is compromised (Kirchoffs' Laws).
No amount of voodoo speak will solve the problem. This is why I asked Phd to name preamps that can drive better than the output of the OP's PS Audio Dac.
BTW: I don't know how passive came into this conversation, maybe it was just a bit of baiting?? The OP question was just "Is no preamp really better that a good preamp?"
Rustler: Almarg and I have both told you have a great match to go direct, and adding an active pre is going to do nothing but colour the sound and put a hole in your pocket.
