49 dB gain would be 1 Volt output with the VM95 ml so plenty loud enough (not as loud as digital sources though, but this is normal for phono). AT cartridges favor low capacitance, so try 100 pF or no capacitive loading at all. With higher capacitance they might sound bright.
Thanks! 🙏
And thanks Jim to make this even simpler.
I would suggest to add a note to the build doc for the fellows across the pond.
Have finally finished the third build of P3 -- was delayed because of a rebuild of my equipment racks.
Besides positionning and cosmetic changes, there was only one other alteration -- R27 was adjusted on the bench so that both channels had the same current: 4.9mA for the right and 4.87mA for the left (close enough for government work, right?). This required 560R and 600R parts.
Initial listening tests suggest two minor improvements in the soundstage. Soloists panned dead center are placed more accurately between the two speakers and orchestral instruments panned to the rear have a bit more sense of accurate depth. Of course, YMMV, and this is only the case for my equipment -- a VPI turntable with Hana ML (MC) cartridge feeding the P3 to a 2018 Colburn linestage, Aleph monoblocks, then to Tekton Double Impact speakers. The room is well tuned and this makes a great deal of improvement in the soundstage imaging.
Because of the good results (however minor) am going to redo the first two builds to achieve this same mA matching.
One fine piece of audio equipment and have now completed my PhonoStage needs for the forseeable future.

I listened vinyl few hours with XLR,
I want to listen more and more, enjoyed how it sounds.
tried muses01,muses05 X2,muses8920.
01 sounds softer,05 sounds more clear,8920 sound clear, a little thinner.
When XLR output,somehow I preferred muses8920 (3.5usd) for me.
Separate chaissis took time to build, glued iron plate on lid,eventually it was worth taking time and satisfied.
Thank you so much for wonderful project!
