apples to oranges
@Gazny but both are dynamic driver with 300 ohm and ZMF are known to work well with OTL. ZMF VC works well out of DSHA-3F but don't have that amp with me right now.
Sometimes gear just don’t gel? Have you tried a different upstream source?
@joch My belief is the source should be neutral and be able to handle everything well. And it's the amp that works or doesn't work because horses for courses. I use one good source and too many amps for different sorts of transducers.
@joch not recently as only have limited things with me for music atm
