"The electrolytic cap that sits from the plate of that cathode follower to ground will also be in the signal path, and my guess is that you were planning to use at least 100uF."
The degree of "disturbance" created by the power supply cap can be quantified. Measuring the AC present at the B+ side of the cap and applying the PSRR of the stage is sufficient to determine whether the signal is likely to be affected. I am unable to do that easily with a series cap, so I find it preferable to use a small .01u rather than 4.7u for this purpose.
