It takes an open mind to talk about distortion not mattering in the way we would assume. Sort of like people assuming a simpler signal path is always better....
One should never assume but all things being equal (which is a qualifier not an assumption) the simpler signal path is always better. How could it possibly be otherwise?
The above is a perfect analogy. The first statement points out the oft-held assumption and the second confirms that people make this assumption.
Many of us think the way millercarbon does. It makes perfect sense on paper. I have been "disabused" of this notion. My ARC Ref 6 preamp has circuit boards and not PtP wiring and it has a BAT-like maze of capacitors and signal paths from input to output. It sounds amazing. And yes, it has a sound. A preamp on paper should not have a sound, right? (Sam Tellig evil laugh here). Well, not so fast. Those who love their passive or buffered attenuators say yes to that, those of us who have active preamps of the likes of my ARC say otherwise. The debate goes on. This whole concept of all distortion being bad is just another form of the same argument. I think audio enlightenment lies in embracing the reality that there is always distortion.
