Attenuator & Transformer for Moving Coil cartridge


my analog front end is as follows:
- Lyra Delos
-Clearaudio Performance turntable
_ Musical Fidelity XLPS-V3

I am delighted with the sound of this system. Obviously The turntable is connected to the MC connectors of the XLPS.
However, the other night I discovered that I had a SignetMK10T Transformer for Moving Coil cartridges from years ago unused in a box.
I wanted to start playing with transformers feeding into the MM input of my phono stage but then noticed that with the step up ratio of 1-15 of the Signet, given that Delos produces 0.6 mV this will present 9mV to the phono stage which is clearly way too high.

so my basic question is could placing HIFI quality attenuators between the transformer and the phono stage bring the voltage down to an acceptable 5mV level?

Would this have an adverse effect on the sound quality gains of using a transformer ? if not what value of attenuation should be used?

Thanks in advance for all your replies and advice.

I should have said it myself; try it (the 1:15 SUT with no attenuation of its output).  You can't break anything.  I concur with the others that it might work OK.  Except I don't necessarily agree that a good MC phono stage is never as good as MM + SUT.  But that's not the question here.


No no no. If you’re serious about a high quality result, I would not advise placing any sort of attenuator in line between the tonearm and your phono stage. Unfortunately, the best choice here would be to try to find an SUT with a 1:10 or lower step-up ratio or a phono stage with more gain.
