I have limited experience with cathode follower mics and transformers. Historically, aside of AKG's late-period tube mics, and a Sony here and there, these were the exception to the rule of at least 6:1, often higher ratios in plate pick-up circuits.
And I could never tell much of a difference in sound when I experimented with different transformers in mics with cathode-follower circuits.
My question: do 4:1 or similar low-ratio mic level transformers show less of a sonic difference than the higher ratio ones typically used in classic mics? And is that because of the lower ratio between primary and secondary windings, and the relatively uncomplicated processing of such transformers?
