Suggestions for phono preamp for LOMC's

Another Allnic recommendation here. Their new step up transformer uses silver windings, which is an audible enhancement.

I am using the Sun Valley Phono EQ which is a kit (though you can pay to have them assembled) with a Lundahl SUT and it sounds absolutely incredible. I also have a Hagerman Trumpet (with an upgraded power supply), Bottlehead Eros and a Pete Millett LR Phono stage I built and the Sun Valley blows them all away. 

Tavish Adagio is nice, but there's a (long) wait list.  Compared favorably with my Modwright PH9.0 and I heard the tube rectifier upgrade takes it to the next level.

Zesto all day long.

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
