Hi, I run 2 cartridges a Lyra Atlas and a Jan Allaerts MC2 Finish. The Lyra is very easy to amplify...and works well with my Nagra VPS and it's MC card with Nagra transformers.
The Allaert's I've tried a few external SUT's with good results (most recently a EAR MC 4) However had issues with the interconnects from the SUT to phono stage being a bit microphonic...
I am very curious to mount custom transformers right on the MM card and eliminating the interconnects altogether. Plus gets rid of 2 more connections and a piece of wire which seems like can only help.
I'll attach a pic of the phono stage. The card on the right is the Nagra MC card with their transformers. The card just to the left, is a MM card with room for transformers soldered onto the card.
Will take any advice you have here. The Allaerts is about .2mv, 32ohm coil impedance. When I used the EAR MC4, I used the 40 ohm tap..giving about 10x gain into my Nagra MM card. I'd take a little more gain...but not less...
Hope all this makes sense...
