I'm very new to the world of MC cartridges so please bear with me here.

I'm currently using a Goldring Eroica L MC cartridge with an output 0.25mV running into my Dynavector 100P Phono Stage which has 63db of gain & 100 ohm loading.

As the output is still very quiet, I've bough a used 1:15 SUT (Klaus Hurler with BD transformers) which is really for a Denon 103r but thought I'd give it a whirl but I haven't noticed any volume output difference at all (in fact if anything it appears quieter than when using the DV MC stage on it's own).

Have I done something wrong here is it just the SUT I've got isn't compatible with my cartridge or Phono Stage?

Thanks.
