[ProAudio] Western Electric 111C transformers

[Scott Dorsey]

You wouldn't -normally- want a series resistor when driving from a low-Z
source... the lower the source impedance, the lower the coloration.

But... if you find the coloration is too low, which you might, then this
is a thing worth trying.

In the past my experiences with the 111C have always been using it as a 
tool to reduce coloration rather than to increase it.
