"A fixed bias circuit is something much more than a negative DC source to your tube grid, it's a combination of elements and each element has its own sound signature. The wire, the resistors, the capacitors, the choke, the rectifier, the transformer and the power cord. The combinations of these elements + the well engineered schematic + the tube operating point will give you a certain sound that you may have to tweak further."
I can see how some of those elements might make their presence audibly noticeable if the bias supply were poorly designed, but it is really not that complicated to make a supply that lives up to its name of "fixed bias." Namely, it should simply produce a voltage that is fixed, i.e. constant in time.
