With a transfo you will hear a C, a resistor and an transformator sound since a transformator consist paracitic resistor and parasitic condenser.

Subject: RE: interstage transformers
The question is not regarding a special amplifier but is an universal question why more and more amplifiers are constructed with transformer as interstage coupling. According to my knowledge there is no any advantage compared to the usual C coupling. It even has a lot of disadvantages.
