When I read the heading I thought you might go down the route of how much time preamps are actually acting as amps rather than attenuators (given line level DAC inputs). Seems like most of it IMO, except perhaps in those low power tube systems.
In theory, digital attenuators on DACs could be problematic, if the DAC isn’t oversampling first. And it seems to me of the output impedance is ill-matched to the amp, we have a design or execution flaw at one end or the other. No?
It was explained to me that impedance matching was more of an issue where analog attenuators were involved. Not really an issue with modern sources having digital attenuators. So I was told.
