Suggestions for phono preamp for LOMC's

Check out the Parasound Halo JC3+ 
I think its performance is very good for the money spent and has tremendous build quality.

"I have about $10k invested in my table/arm"

That suggests you might use a cart around $5K or so?

$2500 retail may not show such a cart in it's best light?

That amount + a few more bucks in a USED $5k +retail unit could do so.

I use the PL. Competitive with the any tube/SS in the $5K+ range

@lewm You are correct. When I used the term “specifically designed for moving coil cartridges” it is because the Modwright phono stages have no problems with LOMC cartridges with outputs of 0.2 and 0.3 mV, not just the 0.5 mV cartridges. Plenty of gain and very low noise levels. 

But does the Modwright use a built in SUT in order to achieve adequate gain for an LOMC, or not?

@lewm No SUT. Just the tubes, including a rectifier tube. You can check the Modwright web site for info about the models currently in production and get a sense of the design approach taken.
